I just bought this Sony DRU-840A DVD/CD Rewritable Drive Unit, I hooked the IDE connector and the DC Input connector (since those are the settings of my previous drive).
When I turned on the computer, I looked in My Computer and it wasn't there So I went to the device manager and it showed up there, but it had the little exclamation sign there. In properties it said something was wrong with it.
EDIT: In the properties of it Windows says:
Windows cannot load the device for this device hardware. The driver may be corrupted or missing. (Code 39) How do I fix/get the required driver?
