install testdisk, then run testdisk and once it is through everything it
does choose the write option. i have had a few i/o error drives working

With an I/O error on your drive, it usually means it is time to get a

Hi Bruce,
Lots of stuff! I am giving it all - it means nothing much to me
(except the I/O error on device!) but perhaps someone can
decipher it and give me a suggestion. At least I have a sector
number - does that help at all?
(Sorry - I have to retype this as my machine is now off-line and
I am on-line with my ancient XP notebook instead).
