| Water Damage
It is recommended to leave recovery of your computer equipment to
professionals. There are companies throughout the country that
offer that service, but if you want to try it yourself, below are
steps to follow.
Unplug all equipment from
electrical outlets (i.e., either remove ALL plugs from the surge
suppressor(s), or disconnect the surge suppressor's plug from
the wall/floor electrical outlet).
If you may need a data recovery
for your water-damaged computer media (you don’t have backups),
be sure to minimize further damage to the media. Here are some
tips:
Leave the computer turned off.
Do not turn the system on or boot up.
Turning on a damaged system
usually will cause further damage, making a data recovery
attempt more difficult and sometimes impossible.
Remove the media from the
system--such as a hard disk drive from a computer--and
immediately place it in an air-tight plastic bag, such as a
Ziploc® brand bag. Do not leave the media out in the air to dry.
Do not dry the media using a hair dryer or other blower. Do not
open the media.
Allowing the hard drive or
other media to dry out may cause additional damage, which may
make the recovery more difficult, if not impossible.
Act quickly to send the media
to a vendor offering professional data recovery services.
For water-damaged media, swift
action may make a difference.
Drain freestanding water by
tilting equipment (e.g., CPU cases, printers) or diskette(s) at
an angle that allows water to flow freely from the unit until
the unit is dry.
Optional: Disassemble
equipment into the smallest components possible.
Let all components air dry
under a constant air flow (e.g., oscillating fans; open windows
with strong cross ventilation); make sure that all components
are resting on an absorbent surface (e.g., multiple layers of
paper towels, lint free fabric toweling, etc.) - change the
absorbent material as often as needed. Gently rotate hardware
components (in all planes) from time to time.
Make sure that all diskettes
are dried in as horizontal a position as possible.
Once equipment components are
dry, carefully reassemble them.
Plug external modems, printers,
or externally powered monitors into a surge protector and turn
them on – (all that is being ascertained is whether the power
light comes on for that piece of equipment.) If the power light
does not come on, continue to dry the item and try again; if
there is still no evidence of an active electrical connection,
the item will have to be replaced. These procedures DOES NOT
apply to computers (see paragraph below).
For computers, reassemble only
the CPU case, motherboard and power supply. Test this assembly
as describe in the paragraph above; if there is no evidence of
an active electrical connection, continue to allow the
components to dry and test again. If there is still no sign of
power, replace the computer's power supply; should there still
be no sign of an active electrical connection, the motherboard
will have to be replaced.
**Note once an active
electrical connection has been established, turn the equipment
off, install the remaining pieces (one at a time, sequentially -
monitor, RAM, floppy disk/hard disk controller, I/O, internal
modem, other) and separately test each configuration. Then
connect the diskette drives and test this configuration. Finally
re connect the hard disk and test the final configuration.
Backup tapes that have water
damage should NOT be inserted into a tape backup unit even if
you think the tapes have been dried out. Water can still be
present between the layers of tapes. They should be sent to a
company specializing in this type of recovery.
