Files not seen by XP

I backed up files on my old PC using hp cd writer software with the windows 98 operating system. I’m now trying to upload these cdr’s on my new laptop which uses windows XP. Unfortunately XP sees these disks as blank, even though 98 saw the files with no problems. Does anyonme know of software that can be used to allow XP to see these files?

try isobuster @

install aspi 460 as well. 460 is the best aspi to date imho.

I have installed the isobuster software using XP operating system & it is still seeing the disk as blank. I’m pretty sure this backup cdr was readable under windows 98, I may have to check this disk with a 98 operating system.
