some free one on Cnet Downloads.
I recently installed W7 (32 bit) on my Acer Aspire 9410-2597 laptop, and haven't been able to burn DVDs since. At first, it wouldn't recognize my TSST corp CD/DVDW TS-L632D (ac00) drive unless I had an OEM disc in- which it reads just fine. Then I read about having to uninstall quicktime/itunes. Once I uninstalled them, W7 now recognizes that I have a drive but keeps telling me I either don't have a disc in, the disc is bad, or that it's the wrong kind of disc. I ran Microsoft's Fix It (http://windows.microsoft.com/en-US/windows-vista/Troubleshoot-problems-with-CDs-or-DVDs) which allowed W7 to recognize that there is a disc in the tray. Sometimes it will pop up a window to burn a DVD then it gives me a list of all the discs it finds acceptable, one of which is the same kind (DVD-RW) I currently have in it. This is one of the blank discs from the same stack I used when I had Vista. And yes, I have tried several of the blank discs, so the individual disc is not the problem. And, there are no further firmware updates for the drive.
I would appreciate any help I can get. I am also having an issue with W7 saying it can't back up to my Maxtor One Touch 4 Plus because it's is corrupt, which I know it isn't, but I'll repost for that.
