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).

ata1.00 status; { DRDY ERR }
ata1.00; error: { UNC }
ata1.00: configured for UDMA/133

Thanks,
