Maybe try ddrescue ?

I tried testdisk WIP last version and the dd_rescue
unfortunatelty they give nothing about it ... testdisk hangs forever, freeze several hours , i.e. like fdisk -l

and dd_rescue with the several options, it did also not see the disk, or hanged during 30 minutes without doing anything : progress remaining to zero

Seems very tricky problem. Windows XP can see it a bit, but not linux :-(

Well, then get all the data off ASAP, from Window$ if it works, I think the drive is gonna die.

I think its time to replace that drive and write your backup copy on the new one.
