DvD/RW stopped working in new system

I upgraded my motherboard, CPU, RAM, and case, but still use the video, HDD, and other peripherals.

Unfortunately, my dvd, which was working fine with the old hardware isn't working with the new hardware. It is recognized in the CMOS settings. The drive is SATA.

I uninstalled the drivers and device through device manager but no joy when Windows 7 detected a "new" device and reinstalled the drivers.

Also, I tried putting the drive in a different computer and it still doesn't read.

I checked the drive head and it moves freely; I left it extended to reset it. Still no joy.

The drive didn't take any large bumps or drops at all while changing the hardware.

I'm just about ready to give up on this thing, but it keeps nagging at me that it worked fine with the old hardware.
