by Chris Preimesberger

2 of 14

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

Good probability of recovery.

3 of 14

Computer viruses:

Good probability of recovery.

4 of 14

Software files corruption (database file gets corrupt because of a software glitch):

Good probability of recovery.

5 of 14

Media logical problem (file system corruption, etc.):

Good probability of recovery.

6 of 14

Media physical problem with bad electronics (circuitry of the media goes bad):

Good probability of recovery.

7 of 14

Media Physical problem with internal damage (bad head stack) [Magnetic Hard Drives only];

Fair probability of recovery.

8 of 14

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

Fair probability of recovery.

9 of 14

Natural disasters (flood, fire etc.):

fair probability of recovery.

10 of 14

Dropped storage meeting in a laptop got dropped or an external drive:

fair probability of recovery.

11 of 14

No Title

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

12 of 14

Degraded tape media:

fair probability of recovery.

13 of 14

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

poor to fair probability of recovery.

14 of 14

Known manufacturing defects causing loss of access to data:

poor to fair probability of recovery.
