Data loss

by Lo In reply to Data loss

Hi - Data Loss is a bit vague. In what context? Databases, Network, Data Transmission, Applications (MS Word, MS Excel), Hardware (disks, tape drives, cd media, memory, printers), etc.

A bit more specific question will most likely get a much better answer.

A bit beyond my field/expertise but ... bad software, bad hardware, exposure to magnetic / electrical fields, virus, mallicious (sp?) users, external such as cut wires (network, dialup) - lo

Data loss can be a result of the following:

Failing Disk media.
If you have a server and you are encountering this problem, you should look into replacing the Hard Drive. Intel's web site has a pretty good tool in helping you to determine what's wrong with your server's Hard Drive you can visit at www.intel.com the name of the software is IO Meter and its free.

Virus Attack can also be another cause for data loss. Always make sure that your data is protected with the latest Antivirus software.

A lesser known cause for data loss is if your Hard Drive is configured incorrectly. Make sure that you are using the correct specs. for your Hard Drive etc.

Bad Media
Mostly happens on floppy type material
going bad..

Not shutting down properly or computer
locking up and forcing a reboot.
Causes file (s) to be left open. data
becomes lost chain or totally unreadable..

Surges and spikes
If you are reading or writing to disk while a
spike is recieved it will corrupt the data
transfer and could, if strong enough
damage the media.

Power Harmonics / EMI / RFI
These come throught the ac line. They
can be caused by large non linear loads
starting and or stopping, motors. Noisy
inductive loads, like a coil in a coke
machine. Radiated RF like from a TV or
transmitter. RF can be introduced directly
in to the computer if it is close enough
and or strong enough.

Loss of power or dip in power
Loss results are same as not shutting
down properly. Power dip if it is low
enough that the power supply hang time
is exceded the will cause data transfer to
be interrupted and corrupted.

Virus
Anything and everything that a sicko can
think of to do to your system.

SafeGuards that can be taken.
Never trust floppy type media for backups
or long term storage. They will go bad.

A good UPS. APC Smart Ups or Backups
This will protect against brown-outs
(power dip) and black-outs. The good
ones also have surge and EMI/RFI built
in. Note: Please do not by the cheepest
thing out there. All of the UPS makers
have a formula to plan which unit to buy.

A good surge protector. APC, Panamax.
ect. A good surge protector will cost
around $40 bucks. Anything less and you
are only going to get a mov across the
acline. If the company doesn't provide a
warranty protecting the equipment that's
plugged in to the strip, don't buy it. A good
surge strip will also protect against
EMI/RFI.

Aside from the listed items above the
best protection from lost data is a backup
routine.

Hope
