Operating particulars: WinXP Pro 2600 SP2. DVD/CD R/W Sony Combo Drive DRU 510A, ram 358m, hd 80g. Device Manager shows no problems, and drive, controllers and adapters all working properly.

Problem - cd will read if it is in drive at bootup If there was no disk in drive at bootup the first disk inserted since bootup it will be read. In either case once read no other disk will be read, and is the only one that will appear in anyone of four different file browsers I have tried (windows explorer, 2xexplorer, My Computer, and a Commander type browser) and will continue to appear there even if the disk is removed. No other disk inserted will appear in the browsers. Somehow the first disk between boots gets read into memory and cannot be displaced. I have done all the things that my research could suggest, including checking the autorun condition both in the drive properties and in the registry. checking the DMA, and of course checking all the connections. I have uninstalled each of the browsers leaving only one of them in turn. I have removed and reinstalled the Sony drive. Nothing changes. I am at my wits end - can any of you good people help?
