Stellar Phoenix Windows Data Recovery

Though Mac systems are quite advanced and reliable, sometimes, some operational or hardware/software errors left you blank and you realize that technology like Mac recovery always weights a prominent value.

Scenario:

As like every other day, when you started your Mac computer, the booting process halted and your hard disk became completely inaccessible thereof. Your head started drilling as from last 3 weeks you have not backed up your data. Now, everything lies on a trusted Mac Recovery software to get back your important data.

Error:

The Sad Mac icon appears during start up and booting process halts.

Probable cause:

Either the disk’s device driver software is damaged, or a more serious problem lies with your hard drive.
Resolution:

Use the System Installer CD and try to locate the hard disk.

If you are unable to locate the hard disk on the desktop, RAM parameters must be reset to its factory defaults, so that the computer can locate the Startup Disk.

Keep pressing the ‘P’ and ‘R’ keys during start up. Your Mac system must chime at least twice before you release the keys.

If the above measure fails, may be your device driver software is damaged. Try to rewrite/update the driver with the software that was used to format the hard disk.

Completely remove the security programs such as DiskLock, Empower, or FolderBolt before updating/installing a new driver.

If you have an Apple hard disk, use the Drive Setup program on the System Installer CD-ROM. Other than Apple disk, try the software that came with your hard disk or any third-party formatter.

If all the above fails, then only formatting and fresh installation will resolve the issues. In this case, to get back your lost data, you have to take the help of any effective Mac hard drive recovery software.

If no other option lies to resolve the issue, you have to do the formating of your drive and it will surely erase all your data in the hard disk. However, after formatting the drive or before doing so, it can be advisable to try an available Mac recovery software, that can recover back your inaccessible or lost data. These Mac hard drive recovery tools are easy to use and are cost effective with respect to the fact that these can recover back the valuable data.

Stellar Phoenix Macintosh Data Recovery is an efficient Mac recovery software that comes with high-end recovery techniques. The software is capable of retrieving your precious data from any troubled Mac hard drive. It can recover all most all types of deleted files or volumes including PTF, AAC, MXF, MUS, NSF, PMD, SHW, PS, VMX, EPS, ENC, fh3, fh5, fh7, fh8, fh9, fh10, fh11, and plist. It supports Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

Macs are famous for their robust functionality and reliability. However, the best machines can have serious problems. It may be a Mac OS X problem or any hardware failure, at the end of it, it is your valuable data that lies on stake. As backup is sometimes unavailable or fails to restore the data, right diagnosis, repair, and Mac Hard Drive recovery tools can make all the difference in recovering your data.

Scenario:

You tried to connect an external hard drive to your Mac computer. The drive is not recognized by the system and you receive the drive inaccessibility error message. The Error message reads like:

“Directory cannot be rebuilt, the file system is unsupported.
This disk is not a Macintosh disk.
This disk does not appear on the desktop.
This disk is <disk size> in size
Drive Format: FDisk Partition Scheme
File System: Windows/PC”

Explanation:

In this case, the drive does not show in the Disk Utility leaving the data in the external hard drive completely inaccessible.

Causes behind the issue:

Above unusual behavior by the Mac OS can be due to the corruption to the file system of the external hard drive. The corruption may have taken place due to virus attack, unexpected system shutdown, disconnecting hard drive without stopping current process or power outages.

Resolution:

• Try to repair the drive with disk utility.

While using disk utility, you might encounter the following error messages:

“Disk Utility stopped repairing drive1” because the following error was encountered:
The underlying task reported failure on exit”

Failure of the disk utility leaves you with no other other option rather than any good Mac HDD Recovery tool. These applications use powerful scanning mechanisms to scan the damaged hard drive and extract all most all the lost or inaccessible data. The good thing about these recovery softwares is that they do not require any prior knowledge or technical expertise.

Stellar Phoenix Macintosh Data Recovery is one of the leading products in the field of Mac Recovery. This is an excellent software that can successfully recover most of the file categories including application files, media files and library files. It supports recovery from HFS/HFS+/HFSX/HFS Wrapper/Fat file system volumes of Mac OS X10.5/10.4/10.3.9 and a really worthy choice in case of Mac Hard Drive Recovery.

Though it may be that much friendly for the user, but  LINUX is more secure and organized in terms of functionality. In LINUX, you don’t get everything preloaded and there is a command for every action in it. Here, there lies a big hierarchy of files and the ‘mount’ command tells the operating system that a file system is ready to use and associates it with a particular point in the system’s file system hierarchy.

Sometimes, the mount command does not work and thus the drive can not be accessed. The cause may be the corruption to the Linux file system and It results in critical data loss. To fix up these issues, power packed Linux hard drive recovery are the only answer.

‘fsck’ command is used to check the consistency of a file. Trying ‘fsck’ command after failing to mount, you may receive an error message.

The Error message may read like the following:

“[/dev/mapper]fsck -a /dev/mapper/mpath0p1
fsck 1.35 (28-Feb-2004)
ext2fs_check_if_mount: Input/output error while determining whether /dev/mapper/mpath0p1 is mounted.”

OR

“fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/mpath0p1
/dev/mapper/mpath0p1:
The superblock could not be read or does not describe a correct ext2
file system. If the device is valid and it really contains an ext2
file system (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>”

Explanation:

When you try to resolve a file system corruption problem and mount the hard drive while  using fsck command, you may get the error message indicating that the file system is inconsistent. Such circumstances lead to the failure of LINUX recovery using fsck command, and your data will remain inaccessible.

Resolution:

Boot the system in single user mode and Unmount the drives.

Check for the presence of file system, if not, apply fsck on raw drive.

If the above fails, only through LINUX hard drive recovery software, your data can be brought back. These applications incorporate high-end scanning techniques to ensure safe and successful recovery. With a friendly user interface, these tools are a boon to users who don’t have prior technical knowledge on the same.

Stellar Phoenix Linux Data Recovery is one of the robust as yet easy to use LINUX data recovery tools. This efficient software supports recovery from all Ext4, Ext3, Ext2 and ReiserFS file system volumes and is compatible with most of the popular flavors of LINUX available in the market.

Are you unable to change the ownership of your mountable Linux hard drive volumes to make them accessible on LAN? Does the process fail with both root user account and local account? Actually, this behavior occurs if you do not have appropriate permissions to change the ownership of the disk or some significant system files are damaged.

Since the system files are damaged, they can not even be accessed by the regular users. This causes grave data loss situation and calls for Linux recovery, if the backup is not updated.

As a practical example of this problem, you may encounter the below error message every time you try to change the ownership of mounted hard drive on Debian Linux operating system based computer:

“debian:/# chown -v ryan:ryan /mnt/hdc1
failed to change ownership of `/mnt/hdc1′ to ryan:ryan
chown: changing ownership of `/mnt/hdc1′: Operation not permitted
debian:/# chmod -v 777 /mnt/hdc1
mode of `/mnt/hdc1′ changed to 0777 (rwxrwxrwx)
debian:/# ls -l /mnt/
total 16
drwxr-xr-x 4 root root 16384 1969-12-31 17:00 hdc1
debian:/#”

The “Operation not permitted” error may also occur if you try to mount a Linux hard drive volume, access data from a volume, move data from a location to another, or change the active partition.

Root of the problem:

This behavior may occur due to any of the below reasons and put you in need of Linux hard drive recovery alternatives:

One or more attribute bits of the directory or file are set incorrectly. It prevents you from changing disk permissions using the chmod command.

The root directory, which is repository of all sub-directories and stored data, is damaged. Thus operating system is unable to read structure of the disk.

System data structures, like file system, superblock, and iNode are either missing or corrupt. These reasons are responsible for making your Linux hard drive unusable.

Resolution:

To fix this problem, you need to repair or replace the corrupted data structures with new ones. It is possible by formatting the hard drive and reinstalling the operating system. But, this process eventually removes all your data from hard drive and causes further data loss.

In such cases, Linux hdd recovery software come to your rescue. They are advanced commercial utilities, which thoroughly scan your hard drive using high-end scanning methods and retrieve all lost data. The Linux recovery tools are easy and safe to use.

Stellar Phoenix Linux Data Recovery software successfully recovers lost, missing, inaccessible, and deleted data from Linux hard drive. The software salvages data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes of all major Linux distributions like SUSE, Debian, Red Hat, and Mandriva.

A lot of us use the dual boot systems in which multiple operating systems, such as Windows and Linux, can be accommodated in an effort to get the best of all worlds. Using such systems can be very helpful when you have to test certain software on various platforms.

In these systems, you have the option to switch to the particular system at the startup. However, sometimes due to various reasons the system is unable to start. In such situations, you should resort to performing in-place methods to fix the problem. If you are not able to address the situation, then you should use a third-party Linux recovery software to resolve the issue.

Consider a scenario wherein you have converted your system in a dual-boot system with Windows XP and RedHat Linux distribution. While in the Windows system, you accidentally clicked the ‘Hibernate’ option instead of the ‘Shut Down’ option. Now, when you start your system you are unable to do so.

Cause:

The root cause of this problematic situation is that when you chose to hibernate rather than shut down, then the MBR may have got overwritten by the GRUB. Therefore, you are unable to start the Linux system.

Resolution:

To resolve this issue, you need to restore the GRUB. To do this, you need to perform the following steps:

• Boot the system with the Fedora (RedHat) distribution CD.
• At the boot prompt, enter the following command and press Enter.
• boot: linux rescue
• You will prompted for few questions. Answer them and the Fedora installer will mount the system in the /mnt/sysimage directory.
• Make the directory as your root directory by using the following command:

# chroot /mnt/sysimage

# _

• From here, use the following command to install GRUB loader on the MBR:

# grub-install /dev/hda

• Restart the system. It should be able to boot properly now.

However, if the problem is still not resolved then you should use reformat the hard disk and reinstall the operating system. But this method would remove all the valuable data, in all probability. So to restore the inaccessible data, you should use a third-party Linux hard drive recovery software. Such Linux recovery tools are read-only in nature that use fast yet sophisticated scanning algorithms.

Stellar Phoenix Linux Data Recovery is a Linux hard drive recovery software that recovers lost, deleted, or formatted data from inaccessible Linux hard drives. It is able to recover data from various file systems such as ext2, ext3, ext4, FAT32, FAT16, and FAT12.

Also, this Linux recovery software is supported by various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Are you getting “Inaccessible Boot Device” error while booting your Microsoft Windows computer? Is your Windows computer unbootable and your valuable data inaccessible? In such cases, you cannot log into Microsoft Windows computer and thus cannot access stored data from Windows hard drive.

It renders your system completely unusable and lead to serious data loss situations. In the event of data loss, hard drive recovery becomes need of hour, in case you do not regularly update your backup.

As a practical scenario of this problem, in Microsoft Windows computer, you may run across any of the below error message when you try to boot your Windows computer:

STOP: 0×0000007B (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE

Setup has encountered a fatal error that prevents it from continuing.
Contact your product support representative for assistance. The following status will assist them in diagnosing the problem.
(0×4, 0×1, 0, 0)
Setup cannot continue. Power down or reboot your computer now.”

You may also encounter the “Stop 0×0000007B” error during Setup process of Microsoft Windows XP. When it occurs, you cannot extract data from your system. To retrieve inaccessible data, you must identify the cause of this behavior and recover hard drive data by sorting it out.

Causes and fixes of the problem:

This problem may occur due to any of the following reasons:

Virus infected boot sector- The viruses have damaged the boot sector of your Windows computer. There are various boot sector viruses that make your system totally unbootable. If it is an intermittent problem, check your system for viruses.

Problems with device drivers- A corrupt boot controller or Windows registry information about the device driver can lead to this issue.

Corrupt boot volume- The Windows XP boot volume is damaged and it can not be initiated. In case file system is damaged and Windows is unable to initiate boot volume while booting, you can either try creating a parallel installation or running chkdsk on the drive by attaching to another Windows computer.

If you are unable to fix the problem using above fixes, hard drive data recovery becomes need of hour.

Recovery is best possible using powerful and advanced hard drive recovery software. The applications use advanced scanning techniques to ensure absolute recovery of all your lost data.

Stellar Phoenix Windows Data Recovery is the best data recovery software ever made to ensure absolute recovery in all data loss situations. It works well with Microsoft Windows 7, Vista, 2003, XP, and 2000. The software supports recovery from NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

Hard drive is the main storage device in any Linux computer. It stores all your significant data, applications, and Linux operating system. You can divide this non-volatile mass storage media into various volumes, for effective management of your significant data. Hard drive stores all the data on moving magnetic platters, which provides extremely fast data accessing.

It is considered as a reliable storage media, however you should create regular backup of your significant data to ensure absolute data safety. Backup is the identical copy of your precious data that helps you to prevent data loss and need of Linux hard drive recovery solutions.

Under some circumstances, your may not access your valuable data from Linux hard drive, can not boot up your system, and come across other similar situations. It can be caused due to logical damage to Linux hard drive. The most common reasons of hard drive failure and data loss from Linux hard drive are as given below:

File system corruption- File system is a significant component of your Linux hard drive. It is used by Linux operating system to organize files/directories on hard drive. It file system is damaged, Linux can not locate the files/directories stored  on disk and thus you come across data loss situations.

Virus Infection- Viruses are malicious programs, which may damage data and data structures on your Linux hard drive. They make your system unbootable, inaccessible, and unusable.

Running fsck on a mounted volume- Linux operating systems includes an inbuilt utility, fsck, to check the integrity of file system and fix minor corruption. In case you run this command-line tool on a mounted Linux volume, severe corruption and data loss may occur.

Improper system shutdown- If your system shuts down unexpectedly because of power outage or system crash, current system processes are not stopped properly.

Hard drive formatting- If you accidentally format your Linux hard drive, all the data is removed from it. Formatting also deletes critical system metadata structures.

If you encounter any of the above problems, you need to restore data from most recent backup and perform hard drive recovery.

You can easily retrieve your mission-critical data using advanced and powerful Linux hard drive recovery software. The applications offer easy and safe Linux hard drive recovery with simple user interface and non-destructive behavior.

Stellar Phoenix Linux Data Recovery is the most advanced and efficient utility to offer assured recovery of your valuable data. The software recovers data from all Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system, such as Fedora, SUSE, Red Hat, Debian, and Mandriva.

In the Windows systems, the registry is the hierarchical database that saves all the information of the configuration settings and miscellaneous options. It has the settings for the low-level system components as well as for the third-party applications. Sometimes, when the critical registry entries get corrupted or go missing you are unable to boot the system.

Such situations can arise because of various reasons such as virus infections, abrupt system shutdown, hardware malfunctions, power outages, etc. In such cases, you should resolve to using appropriate steps to address this situation. However, if you are not able to do so then you should use a third-party hard drive recovery software.

Consider a scenario wherein you are working on your Windows 2000 system. Suddenly, there is a power surge and the system shuts down abruptly. You switch on the system when the power is restored but fail to do so. An error message is displayed, that is:

“Windows could not start because the following file is missing or corrupt:
\WINNT\SYSTEM32\CONFIG\SYSTEMced”

Kindly note that the “ced” letters are not part of the message and were actually part of the error message in the previous screen.

Cause:

There could be various reasons for this error message.

A Promise Technology, Inc. ATA66 PCI controller card is installed in the computer.

The System hive in the registry is damaged or missing.

Resolution:

To resolve this error message, you should perform either of the following methods:

Remove the Promise Technology ATA66 PCI Controller: Remove the Promise Technology ATA66 PCI controller card, check the BIOS settings to make sure that the IDE controller on your motherboard is enabled, and then run Windows 2000 Setup again.

Restore a Backup of the System Hive: Use the Repair Console tool to replace the backup copy of the System hive from the repair folder.

Reduce the Size of the System Hive: If a large number of resources are shared on the computer, the registry may become too large. So, you should reduce the size of the System Hive.

However, if you are still not able to resolve the issue and access the hard drive then you should use a third-party hard drive recovery tool to recover hard drive. Such read-only tools are able to perform hard drive recovery and do not overwrite the hard drive while scanning it.

Stellar Phoenix Windows Data Recovery is a Windows hard drive recovery software that enables you to recover hard drive from FAT, NTFS, and exFAT file systems. It is able to recover more than 185 different file types from various storage media such as hard disks, external hard drives, iPods, memory cards, etc. In addition, this hard drive recovery software is capable of recovering deleted emails from MS Outlook and Outlook Express. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

There are some situations where you need to promote your Windows Server to domain controller and to demote domain controller to member server. This is possible using the Dcpromo.exe (Active Directory Installation Wizard) feature of Microsoft Windows Server.

This wizard deletes configuration data for domain controller for the Active Directory, as a part of demotion process.  It takes form of the NTDS settings object, which is stored as child of server object in the Active Directory Sites and Services. However, if  you use the Dcpromo.exe utility incorrectly, you may come across serious problems of system failure and data loss, which ultimately requires hard drive recovery to be fixed.

The information about promotion process and NTDS settings is stored in Active Directory in the below location:

“CN=NTDS Settings,CN=<servername>,CN=Servers,CN=<sitename>,CN=Sites,CN=Configuration,DC=<domain>…”

Attributes of NTDS settings object has data that represents how domain controller is recognized by the replication partners, naming contexts which are organized on machine, default query policy, and whether domain controller is global catalog server.

If NTDS settings objects are removed improperly, Exchange Server administrator can manually delete metadata for server object. Administrator can manually delete NTDS Settings objects in Windows 2003 Server and Windows 2000 Server using Ntdsutil.exe tool. Before you modify the Active Directory attributes or remove server objects, you should keep the following things in mind:

When you use the LDP utility, ADSI (Active Directory Service Interfaces) Edit snap-in, or any other LDAP (Lightweight Directory Access Protocol) client version 3 and you improperly modify the Active Directory object attributes, you may come across serious problems. Such problems may cause operating system malfunction and require you to format the hard drive and reinstall operating system.

You should always make sure that you have complete backup of your mission-critical data after demotion before you manually remove NTDS Settings objects from any server. Incorrect use of Ntdsutil.exe utility might affect Active Directory and cause severe data loss situations.

When any of the above problems occur and you face serious data loss from your Windows hard drive, hard drive data recovery is the best option to sort it out. The hard drive recovery is possible using third-party data recovery software.

The hard drive data recovery applications use high-end scanning techniques to carry out in-depth scan of entire hard drive and extract all lost data from it. The have interactive user interface and read-only conduct to ensure easy and safe recovery.

Stellar Phoenix Windows Data Recovery is the most efficient and advanced utility that recovers lost data in all scenarios. The software is compatible with Microsoft Windows 7, Vista, 2003, XP, and 2000. It recovers data from all FAT12, FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions.

A file system defines the mechanism to store and organize computer files and their data in a computer system. Two basic types of file systems are used in the Windows system, FAT and NTFS. Of these, the NTFS file system is considered more beneficiary for the system as it is more secure, performs file compression, encrypts the files, etc.

That is the reasons more and more users are shifting from FAT to NTFS. However, sometimes when you perform the conversion the Windows system is unable to boot. In such situations, you should use appropriate methods to resolve the issue. However, if you are unable to sort the issue then you should use a third-party Windows hard drive recovery software to do the needful for you.

Consider a scenario wherein you have FAT 32 file system in your Windows XP system. You want to convert the active partition from FAT 32 to NTFS using the ‘convert drive: /fs:ntfs command’. However, when you perform this operation and restart the system, it is unable to boot. An error message is displayed, that is:

“Windows could not start because the following file is missing or corrupt: System32\Drivers\Ntfs.sys”

Cause:

The root cause of this error message is that the Ntfs.sys file has either corrupted or gone missing while you converted the file system from FAT 32 to NTFS.

Resolution:

To resolve this error message, you should perform the following steps:

Boot the system using the Windows XP CD ROM.

Enter the Recovery Console and press R to start the repair process.

Type the following commands and press Enter after each command:

cd \windows\system32\drivers

ren ntfs.sys ntfs.old

The ntfs.sys file will be renamed if it is corrupt. However, if it is not there it means that it is missing.

Type the following command and press Enter.

copy X:\i386\ntfs.sys drive:\windows\system32\drivers [Where X=CD-ROM Drive]

Enter quit, and press Enter to exit the Recovery Console.

Restart the system. The system should boot properly now.

However, if you are still not able to access the data then you should use a third-party hard drive recovery software to do the needful. Such read-only tools are able to recover hard drive using fast yet sophisticated scanning algorithms.
