Thank you for your help :))
I have the following system: AMD 2200/ Windows XP/ 512 MB RAM. The PC works fine. I sweep it weekly for viruses with up-to-date virus files.
I have a 52x24x52 CD-RW drive. I use the very latest version of Roxio software to Drag and Drop files for back-up.
About 6 months ago I purchased some Memorex CD-RW disks: 700 MB "ultra-speed" (16x-24x). All worked fine. I backed-up some files onto 3 of them, then pretty much forgot about them. All were stored well.
Recently, the three stopped working. Shortly after I load them into the drive the PC locks up until I remove them. Once they're in the drive I can't access the Roxio software utilities to try to re-format them.
All other CD-RW's seem to work fine--including the two remaining Memorex CD-RW's I purchased.
Might anyone know what happened here? These CD-RW's seem so finicky. I had similar problems about a year ago, but thought I'd solved the issue when I bought a new CD-RW drive and got the latest Roxio software.
Thank you again for your help. :)
