Strangely enough, the BIOS recognizes it. Power is ok, it is currently set to run as master on the only ATA port on my board (Gigabyte P35 DS3). I have tried disconnecting the device, booting, and then shutting down, connecting and rebooting, different jumper settings, reinstall of the drivers I considered to be in question-all to no avail. Anyone who can point me in the right direction? I am running WIN XP Pro with all hot- and bugfixes except for SP3. Thanks in advance.
