I have a user that has a 530 and was recently upgraded to WIN XP from Win2K. Ever since the upgrade the guy cannot use his CD drive. It opens and what-not, but when it reads the cd the only thing it does is read it as a blank. When you double-click the drive, it just opens into a blank window. I have tried swapping the drive with two other drives and the same thing happends. I put the original drive on another PC and it works like a charm! Then I tried to put the drive on IDE one hoping it would be a bad cable or something, but the same thing happened.http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q311755 I tried running a repair on it, but when it came up to the installing windows part, I get that ASMS message described here: . I also tried to restore but I do not know the admin password (since the machine is from a newly aquired company, neither does anyone else here). If anyone can help, I would deeply appreicate it! Thanks a bunch.
