Hard Drive Recovery – What’s Wrong?

To understand why you may require hard drive recovery services on your disk drive it helps to understand the two main categories causing data loss.


The hard disk drive (HDD) is operationally functional. Data Recovery is required because the file system structures (think of an index) that are used by the operating system to locate your data have become corrupted, overwritten, deleted, or possibly even orphaned from the file system.screen showing File system damage
Examples of operations that may cause these issues include; Re-Formatting, File or Folder Deletions, Re-Installation of Windows or Operating System, Virus Damage, chkdsk or other utilities being run, Deleted Volume, Master Boot record bad, Read errors, and Encryption gone bad.

If you have deleted files or folders, stop using your computer immediately to ensure the best chance of recovering your hard drive data. Even booting up will write data to the hard drive that may jeopardize your deleted data. If its important do nothing else but seek  a professional hard drive data recovery service like Memofix Data recovery Services.


PHYSICAL DAMAGE (Electrical or Mechanical)

Damage to the hard drive’s PCB or printed circuit board is often the result of electrical surges through the power system and often a result of lightning storms. Beside the PCB there is also an amplifier chip or IC (integrated circuit) located on the drive’s head assembly in the sealed bubble that can be damaged as a daisy chained event after the main PCB is blown.

Physical damage to the heads and disks is often due to an external drive being dropped or knocked over. But even internal drives can become physically damaged if the the drive’s sealed interior is violated or just due to old age. Some drives that land the heads on the disks (versus off the disk ramps) at power down are more susceptible to crashes as the lubricant on the disk’s landing areas becomes degraded. Most Seagate drives land their heads on the disks, while Toshiba, Hitachi and Western Digital hard drives utilize ramps to take the heads off the disk on power down. Hard drive recovery
