Data CD files recovery with Linux?
A large proportion of files on a multisession data CD have become inaccessible. I have tried CD Check and CD Recovery Toolbox, to no avail. OS is XP Home; app used to burn is Ashampoo Burning Studio Free 6.75. I have had this problem in the past, using just the XP burner, so I'm not blaming Ashampoo.
Burnaware Free and Ashampoo can see that there's more data on the CD than they can access.
I have found out a little about Knoppix. Would it, or another Linux variant, offer a different way of accessing the CD, so as to recover the files not seen by XP and XP-based apps?
CD media used is mediocre-quality stock from a very large grocer. I guess there's a lesson there...
