I've recently purchased an off-lease Dell GX270 tower, 3000 MHz, 1000 MB RAM, running Windows XP Pro, Service Pack 2. Everything seemed to be working fine until I purchased an LG external DVD-RW drive, specifically the GSA-E40L. When I put a cd into the drive the motor raced really fast and sounded like it was going to take flight. It started right after the drive read the cd and sometimes stopped after a couple of minutes, or rarely didn't do it at all. This whirring noise wasn't consistent with what I was doing at the time (starts before I began ripping songs into my computer and sometimes stops before I'm finished). It usually didn't stop racing until I ejected the cd. Anyway, I had seller send me a replacement drive and it is doing the same thing. I've tried it in 3 different 2.0 usb ports (including front) with same results. I also have other hardware plugged into this computer's ports with no problems, including ipod, cordless keyboard/mouse, Seagate external drive, etc. I don't have access to another computer with 2.0 ports to test the drive in. Sorry for writing a novel, but any suggestions?
