Physical Causes of Data
Loss (continued) Physical problems also include failure of electronic
components on the drive’s controller board due to: ØElectrostatic
Discharge (ESD) or heat. ØPower loss or power
surge. Physical problems affecting the computer equipment may also
render data inaccessible even though the media (that it is stored on) still functions perfectly: ØSudden power loss
may corrupt open database files. ØComputer memory
glitches may result in bad data being written to sensitive filesystem control
areas. ‘Soft’ Causes of Data Loss ‘Soft’ causes in this context means non-physical
causes. These are also referred to as
“logical’ causes. Soft problems can
usually be related back to something that someone did or did not do, in other
words “human error”. Oops! ØAccidentally
deleting files or reformatting the system. ØA tape containing a
good backup was partially overwritten because it was inserted out of sequence
during a tape rotation. Ø“Failed restore”. Restoring
from a backup can be a lengthy and error prone process. This can include tape
format or compression errors |

ØViruses. The malicious work of a smart sociopath. ØConfiguration
errors due to the complexity of the system. |
