Why Data Loss Occurs
typical causes of disk drive data retrieval problems are:
to Avoid Further Data Loss
your drive is making unusual noise
back up your data immediately if possible and run your disk drive
as little as possible until you have recovered all of your important
data. Noise is an indication of physical damage. Continuing to
run the drive under such circumstances is likely to make matters
you are having trouble reading important data from your disk
drive but still have access to the drive do not attempt to use
disk drive utilities to recover the data unless you are sure that
you can undo your recovery efforts. In particular you should avoid
using any utility that writes to the damaged drive. These utilities
can further scramble the data on your disk making recovery more
difficult or even impossible.
you think you may have deleted or erased important files or directories
from your disk drive do not save or write to your disk drive until
the data has been recovered. The data may still exist on your
disk. Writing or saving to the disk may overwrite the data you
want to recover making it unrecoverable.
Data Loss From Occurring
drives of all types are mechanical devices subject to wear. They
are more vulnerable than many of the other components of your
computer system. They are also the repository for your valuable
data. The best form of prevention of data loss is to perform regular
backups of your data. The more frequently
the backups are performed the less data will be lost in the event
of a disk failure. The more important the data the more often
it should be backed up. For really important data storage consider
disk mirroring where data storage is duplicated on two drives
at the time it is written to disk.
your disk drive is making loud or unusual noises
this is a symptom of physical damage to the drive. If you can
still access your data, make a backup of your data immediately.
Do not run the disk drive except to back up your data. If you
can not access the data on your drive shut the drive down immediately.
The longer you run the drive the greater the chance of causing
irrevocable damage to your data.
you are getting hard disk boot failure errors boot your computer
from a bootable floppy disk. Attempt to get a directory of your
hard disk. If you can get a directory of the hard disk make a
backup of your data immediately then see what you can do to repair
your boot problem. If your computer does not return directory
information check your cmos setup for the hard disk.
you can not recover the data yourself using methods that you
know to be safe stop using the disk and contact a professional.
The longer you work at trying to recover the data yourself without
being absolutely sure of what you are doing the greater the chances
that you will make matters worse perhaps even making it impossible
for a professional to help you. Often when data appears to be
lost it is really still on the disk somewhere and it is only the
normal access to the data that has been compromised. But once
the data has truly been erased or overwritten there is nothing
anyone can do to recover it for you.
