Stellar Phoenix Windows Data Recovery

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.

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.

Are you facing problems in booting your Linux system? There may be a possibility that the hard disk of the Linux system has got full thereby disabling you from mounting the system. In such cases, you should use the Boot CD to enter the console and perform Linux recovery. If you are not able to fix the problem, then you should use a third-party Linux recovery software to perform Linux hard drive recovery.

Consider a scenario wherein you have installed Red Hat 9 in the root drive of your Linux system having ext3 file system. You did not realize about the size of the root drive. When you start the system next time, it failed to start up citing some corruption issues.

Cause:

The root drive has got full due to the installation, and it has become inaccessible. You need to remove some excessive files to be able to remount the Linux system.

Resolution:

To resolve this situation, you should perform the following steps:

• Start the system with the Boot CD.
• Choose the ‘rescue’ function during the installation procedure. It should land you in the console.
• Mount your /root partition using the following commands:

console$ mkdir /mnt/root

console$mount -t ext3 /dev/hdax /mnt/root

• Subsitute the ‘x’ in ‘/dev/hdax’ with correct value as suggested in the following commands:

/dev/hda1 for first partition

/dev/hda2 for second partition

/dev/hdb1 for first partition on second hard drive

• Delete the unnecessary files by using the ‘rm’ command as shown in the following command:

console$ cd /path/to/the/directory/

console$ rm -r <directory or file>

• Restart with ‘iinit 6′ or ‘reboot’. Now, you would be able to start the Linux system properly.

If the problem is persisting then you should format the Linux hard drive and reinstall the Linux operating system. However, that would mean that the valuable data will be lost. In such situations, you should use a third-party Linux recovery software to recover inaccessible data. Such Linux recovery tools are read-only in nature that do not overwrite the existing data while scanning the hard drive.

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.

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.
