Hi,

I burnt 2 different brand blank DVD-R's a couple of months ago with Data files off my HDD as a back up and they have worked fine until just recently when i reinstalled my windows XP.. it reads as if they are blank.. its a pretty serious problem as i did not have these files back up anywhere else except on these DVD's and i have used these DVD's around 10-15times each so i know they DID work fine..
Can anyone help???

PLEASE!??
