[Solved] ASRock Super Computer - No USB HD support

I have an external USB Harddrive (Western Digital My Passport 320gb) that works on a number of other systems except for the one I just built. I'm thinking it's a motherboard issue, although I am not sure. Any help would be appreciated, here at the stats:

ASRock Supercomputer X58
Intel Core i7 920
12GB OCZ DDR3 1600
NVidia GTX 275
Western Digital 1TB SATA HD
Lite-on 22x DVD-R
CM Stacker 830SE Case
Corsair 750W
Windows XP x64 (I have also tried with a LiveCD version of Ubuntu 8.10 x86 and 8.04 x64, same results)

Basically what happens when I plug it in is the lights blink for a second, then shut off. When the machine is booting and it is plugged in, I can hear the computer accessing the drive (although it makes the same sound a dead drive did that I used to have). A few people have suggested that I go into the Disk Management tool under Windows to check the drive, but neither that or my Device Manager sees the drive at all. Once again, thanks for any help.

Hey jsc, thanks for the reply. I tried that and the same thing happened. Just to note, I can plug other usb devices into any of the ports (including flash drives) and they all work just fine. It's almost as if there's not enough power getting out to power the harddrive, although I have no way of knowing/testing this theory(maybe theres a usb power tester out there?). Thanks though for the suggestion jsc, I'm open to any other ideas you may have.

Hmm, tried hooking it to a powered hub (Belkin 7 port) and same thing happened. Tried plugging some other devices into the hub that work fine with this computer, and they were never detected. Tried the hub on another computer and it worked.

I have the x58, i7, 12gb corsair, and the 750 corsair power supply also, and have the same problem.

Actually i have the exact same system at work too, and have the same problem on both. I'm running Vista Ultimate x64 on both also. I tried the hard drive on a WinXP Pro x86 system (different hardware) and all is well.

I've had this problem with 2 different 320gb 2.5 external seagates and 5 different 160gb 2.5 external seagates.

I've come to the conclusion that they are conflicting with the motherboard. I've used seagates exclusively for about 10 years, love them, but these small externals with the x58 supercomputer motherboard just don't fly.


I hope my info can help,
