Hi everybody.
If y'all will remember my Toshiba A100 "System Restore not working" post, thanks to all involved, my laptop is once again shiny! But there is still one remaining problemo. When I try to use my inbuilt CD/DVD drive, the disk, whether it be music, movies or anything else, just whirls around and does nothing. If I try to force start it from 'my computer/ cd/dvd drive/d' it comes up with an I/O error. Trouble is I know it works, because if you remember I had to do a full HDD recovery, and I could only use the 'D' drive, as the recovery utility would not recognise my external usb 'F' drive. The windows troubleshooter says that the drive is ok. Any help folks?
