- 13 Common Data Storage Failures and How Likely the Files Can Be Recovered
- Human error (file deletion, formatting a hard drive etc., The the most common way files are lost):
- Computer viruses:
- Software files corruption (database file gets corrupt because of a software glitch):
- Media logical problem (file system corruption, etc.):
- Media physical problem with bad electronics (circuitry of the media goes bad):
- Media Physical problem with internal damage (bad head stack) [Magnetic Hard Drives only];
- Media Physical problem with bad motor (drive doesnt spin, etc:) [Magnetic hard drives only];
- Natural disasters (flood, fire etc.):
- Dropped storage meeting in a laptop got dropped or an external drive:
- No Title
- Degraded tape media:
- Bad quality or aging CD/DVD storage media (over time the film on a CD/DVD will degrade):
- Known manufacturing defects causing loss of access to data:

Human error (file deletion, formatting a hard drive etc., The the most common way files are lost):

Good probability of recovery.
Computer viruses:

Good probability of recovery.
Software files corruption (database file gets corrupt because of a software glitch):

Good probability of recovery.
Media logical problem (file system corruption, etc.):

Good probability of recovery.
Media physical problem with bad electronics (circuitry of the media goes bad):

Good probability of recovery.
Media Physical problem with internal damage (bad head stack) [Magnetic Hard Drives only];

Fair probability of recovery.
Media Physical problem with bad motor (drive doesnt spin, etc:) [Magnetic hard drives only];

Fair probability of recovery.
Natural disasters (flood, fire etc.):

fair probability of recovery.
Dropped storage meeting in a laptop got dropped or an external drive:

fair probability of recovery.
No Title

Flash media write/overwrite limit exceeded (excessive usage will eventually cause flash memory to fail): fair probability of recovery.
Degraded tape media:

fair probability of recovery.
Bad quality or aging CD/DVD storage media (over time the film on a CD/DVD will degrade):

poor to fair probability of recovery.
Known manufacturing defects causing loss of access to data:

poor to fair probability of recovery.
