Trouble with Artec WRR-52X



Hi, I bought a Mad Dog external cdrw. After opening the enclosure, the cdrw turned out to be an artec wrr-52x. I tried to install the drive internally, but for some reason, it doesn’t read any cds. I’ve tried to upgrade the firmware to the latest (1.25), but still no luck. The computer recognizes the drive, and even installs the driver for it, but whenever I put a cd in it, the led justs blinks and the cd is never read. Did Mad Dog do something to it so that I can’t use it internally? Anybody know what’s going on, or how I can fix this?
Thankx in Advance
