hello gshdet, welcome to CDRLabs.
1. try installing the drive in another computer.
if the same thing happens there it's most likely a defective drive, return it to the store where you bought or have it serviced.
2. try replacing the IDE cable to which the drive is connected. also make sure the jumpers are set correctly.
