Hello all, I have an HP TouchSmart 300-1007 desktop bought in 2010. It has recently stopped recognizing disks, both data or DVD movies. I have performed full scans for viruses and malware, checked device manager (which showed it was working properly), and searched for updated drivers for the DVD drive. I started doing some research on the drive that came with this system, and it looks as if this is a common problem and the fix is a replacement. I have done searches for the drive, but have only found ones for Dell laptops. The drive is an Optiarc DVD RW AD-7640S. Would the ones I found for Dell work, or is there a compatible replacement. Thanks for any help.
