For starters, do NOT try to write to drive, or running disk saving tools, it'll only make things worse. Keep any disk operations to a minimum.
First off all you'll need a hard drive equal of larger of the failing drive. Then use dd_rescue[1] to copy it sector by sector (note that it might take a long time) Make sure all the harddrives are firmly mounted (on BOTH sides) and are cool (aim a fan at them). Once finished you will find an replica of your failing harddrive on your new harddrive, but ofcourse, without the parts that couldn't be read. I recommend using smartctl[2] to examine the failing drive further. Now when that's done you can start thinking about what to do with the failing drive. First off all, can try overwriting it with zero's, with dd_rescue dd_rescue -D /dev/zero /dev/sd[a-z] then execute a SMART long survey test smartctl -a /dev/sd[a-z] -t long To check on the drive's progress, use smartctl -a /dev/sd[a-z] If the test fails with a read error, retry the whole procedure. However, if later tests continue to show read errors, that means you can get a screwdriver and see what's inside ;-) Good luck.
