In case your computer is not able to boot, the hard drive crash can not be the only reason behind it. You should try to reboot the system in a different mode viz. Safe Mode, check all cables and connections. If this doesn’t help, then you need to shut down the system and consult Hard Disk Recovery service professionals.
If system can boot from the hard drive till it can display error reports through video subsystem, it becomes easier for a user to diagnose the actual problem. One of such error messages is:
“Initialization error on HDD0”
Where, HDD0 shows that main hard drive has got failed. Based on number of hard drives attached and their configuration, hard drive number may vary.
The error message occurs when computer system encounters issues starting from the hard drive after POST (Power On Self Test). It occurs due to physical issues with one or more hard disk components (mechanical or electronic).
Reason
A hard drive may get failed due to number of reasons:
• Head Crash: This is a frequently occurring instance. It occurs when read/write head comes in contact with the fast moving platters. It is the prime cause of physical damage to their magnetic material. Data lost post such malfunction is not recoverable.
• Air Filter Crash: Hard disk incorporates an air filter to maintain air pressure levels and moisture. However, when air filter function gets affected due to faults, dust particles may settle down on platter surface and create obstacles in read/write operations. More severely, it may cause head crash.
• Other Components Failure: Other hard disk internals may also fail. This includes spindle motor, spindle, actuator, head arms etc.
• Electronic Failure: A hard disk is comprised of several Integrated Circuits (ICs) that control its internal functioning. Their damage can make hard disk inaccessible.
• External Factors: If hard disk is exposed to high intensity magnetic waves, heat, water, shocks, heat or power surges, it may stop functioning.
• Wear and Tear: The continuous use of hard drives for long time intervals can cause wear and tear to its parts and make them fail. Hard drive manufacturers provide the expected time of failure known as MTBF (Mean Time Between Failures) on their manuals, which is estimated by considering that hard disk is used under normal conditions.
Hard Disk Recovery service helps users to reclaim their lost data from such physically failed hard drives. To determine the cause of failure, affected hard disks are opened under safe environment of Clean Rooms. Clean Rooms are controlled lab environments to perform intensive component level tasks. After the cause of crash is known, hard drives are treated with appropriate Hard Drive Recovery procedures, which are tailor-made solutions as per nature of the problem.
Stellar Information Systems Limited is the premier provider of state-of-the-art hard drive recovery services. The data recovery service is provided in Class-100 Clean Rooms. Our recovery solutions are available for almost all types of hard drives as SCSI, SATA, EIDE and IDE. We also provides solutions for Server, RAID, NAS and SAN hard drives.
