Windows XP - Something Bad Happened to CD-RW

[familyname]

Situation: Last week burned a number of documents to a particular CD-RW. Was able to access files as needed. Today needed to access files and there is nothing there. No files, and according to drive, the disc has all but 400 kb free. As if it were blanked. I definitely did not erase it. That would be more than "slip of the thumb", could spontaneous erasing occur???
When I put into burner, and went through "my computer", there are no files there. Can't find my files, don't know what could have happened to them.

Computer is less than a month old. Running Windows XP Pro. Burner is Artec VOM-12E48X. CD-RW disc is a Sony. Having no trouble reading any other cd-rws. Thanks for your consideration.

You did select "Burn these files to CD", right? You didn't just move them over?

And the disc had been formatted? And you WERE able to see them and access them after the "burn" on the newly burned CDRW?

its Most likely that hes not copied all the files or inproperly selected otherwise the CD-RW is Defective
