SO i got my backup working and xp cant find the partition on them,I need to reset the boot/partition on it so that I can do some data recovery before formating uummmm...help ;_;

I have 100GB of mp3s some old avi's and other crap I don't have backed up what can I do to regain the data on it both HDs wont check disk and show as zeroed out on my computer cant do much with it with what XP has I recall formating from something like this years ago but I can not format this >> there should be some HD recovery/fixing program I can use to patch the boot/partition info to get it to work....I am sick right now I am going to lay down.

correction partition magic 8 can find a partition but the data is scrambled,Acronis Disk Director Suite only uses XPs check disk
