I hope that other forum members will be able to give me advice about recovering data from an unreadable photo CD-R.
My father gave me a CD-R on which some digitized photos were saved about 10 years ago by a photography shop, in JPG-format. The CD-R seems to be unreadable, it is not recognized by Windows at all. There are no visible scratches or fingerprints on the CD surface. After reading through this forum and several others, the most likely explanation for this problem seems to be CD-R dye ageing. (Interestingly, other CD-R media from the same batch do not seem to give any problems.)
I have tried to read this CD-R medium with four different laptops (running Windows 2000, XP, 7), using CD-R, CD-RW, and DVD-RW drives. The outcome is identical for each case, i.e., the CD-R disk is not recognized.
For recovery data software, I tried so far:
Isobuster 3.1: recognizes the amount of data saved on the disk after trying to read it for about 10 minutes (it reports 29.05 MByte, which is about the amount I expect), but also reports that “no file-systems nor files and folders could be found”. When attempting to recover the data then, almost none of the CD sectors can be read.
CD-Roller 9.50: recognizes the CD-R as “type: data CD”, but reports “no file system detected on the disc”.
CD Recovery Toolbox Free 1.1.17 and Finaldata Standard 2.0 do not recognize the presence of a CD.
In the past, I encountered the phenomenon that some CD-R media could not be read reliably on some CD-ROM drives, but would be read just fine on other drives. Would anyone know a particular type of CD/DVD drive that can deal better with difficult cases like my unreadable CD-R? Or are there any other approaches that I could try?
Many thanks for any advice you might be able to provide!
