Disk Crash

Disk crash is a dismayed or dreaded situation resulting in data loss. No hard drive can claim to escape this situation. Excessive usage of disk, mechanical failures or some other reason will certainly cause disk crash one day. One of the best solutions to avoid data disaster due to hard disk crash is backing up of data.

Hard disk crash can be of two types namely, logical hard disk crash and physical hard disk crash. Logical hard disk crash is not severe; the data on it is recovered using disk recovery software like Remo Recover.  The causes for logical hard disk crash could be system crash, corruption of file system, virus attack, etc.

If one of the following symptoms is present, then it is physical hard disk crash, which is very severe:  BIOS not recognizing the hard disk, low performance of hard disk, odd noises (clicking noise) in hard disk etc. In this case, the hard disk has physical damage as the name implies. The data recovery happens only if the platters are safe. The read-write head in this scenario crashes onto the platters thereby damaging them and resulting in loss of data. Head crash causes difficulty to find the correct track due to which readability of data is not possible. The platters rotate at a speed ranging from 5000 rpm to 7000 rpm and in some cases 15000 rpm. The distance between the read-write head and rotating platters is less than 3 nanometers. Read-write head performs read and write operations on the platters. If a dust particle or some other particle interferes in that minute space between read-write head and platter, then it results in jamming thereby causing scratches on platter - head crash. Head crash causes data loss permanently; hence, it is advisable to turn off the system immediately on hearing the odd sounds from the hard disk. Crashed hard drive data recovery done in clean room environments by experts.

Reasons for Hard Disk Crash

  • Mechanical failure
  • Dust, which affects air pocket (between read-write head and platter) thereby damaging platters
  • Power surges
  • Physical shocks
  • Exposure to extensive heat or fire
  • Wear and tear

Preventing the Hard Disk Crash

  • Use of good anti-virus software
  • Backing up of files regularly
  • Proper booting and shut down of the system
  • Avoiding physical shocks
  • Reacting to the warnings provided and troubleshooting them on time
  • Use of inverters or UPS (uninterruptible power supply)
  • Use of voltage guards
  • Clean environment to get rid of dust
  • Replacement of hard disk over a period of time
