What is Data Loss?
|

|
A data loss situation is usually characterized by one (or
more) of the following: ØThe sudden inability to access any data from a previously
functioning computer system or backup. ØThe accidental erasure of data or overwriting of data
control structures. ØData corruption or inaccessibility due to physical media
damage or operating system problems. Have you experienced data loss? If your answer is “yes”, then you are not alone! The majority of computer users will
encounter this situation at some time. Data loss can be caused by physical damage or ‘soft’ (logical)
problems. For example: ØA personal user can no longer access the
“C:” drive on their PC or no longer read a floppy disk. ØA corporate data server has crashed and no longer serves
data to the corporate network. ØA set of medical images backed up on a digital tape
cartridge can no longer be restored. Physical Causes of Data Loss Approximately 70% of data loss cases processed by ActionFront
are caused by physical problems. Occasionally, manufacturing defects or design flaws can cause
mechanical or electronic failures. Most physical problems can be traced to other root causes. Physical problems include mechanical failures due to: ØShock from device being bumped, dropped or moved while
operating causing a head crash or platter misalignment. ØDevice exposed to extreme cold temperatures and/or rapid
temperature change prior to use. For example, powering up a laptop after being
in a freezing car overnight. ØDisasters such as flood, fire (including sprinkler-water
secondary damage) and explosion. ØStiction: The read-write head assembly gets “stuck” on the
disk media due to deterioration of the lubricant or because it has failed to
retract to its rest (parked) position. |
