This one's got me stumped. I have two CD drives on my PC, a CD-ROM (drive E, and a CD-RW (F. The CD-ROM works fine, but recently the CD-RW began doing a strange thing. I can format a disc and both read and write to it. However, when I try to create a new folder on the disc (or rename an existing one) the entire system crashes when I make the next click. I get a blue screen saying that Windows (XP) has closed for my protection, and that I need to reboot. After powering off and on, the system boots normally and all's well until I try again to write a new folder on the CD-RW disc. This writing a new folder process works fine on my laptop (also running XP). Anyone have an idea what's causing this? I don't know if this is related, but drag-and-drop works erratically. In Windows Explorer, I can drag and drop files or folders once or twice, but then get a command to insert a disc in E:, which, as you'll recall, is the CD-ROM drive. If I open and close the CD-RW drive, the message goes away and I can drag and drop once or twice more before getting another insert disc in E: order. Since this glitch does not prevent me from backing up files and loading new software, finding the answer is not urgent. But it could indicate that there may be a bigger problem in store down the line. Here's hoping someone will have a suggestion.
