More information would hel
Thxs for your reply. This PC is a Lan Box that I built about a year ago. It has 4 USB 2.0 ports. I presume that they are working fine due to the fact that I use them normally for my Printer, and keyboard. the two in the front of the PC I have used off/On for my GamePad which when inuse work just fine, but this si the second extrnal Har Drive that I've purchased and it has recognized either one of them. I thought it was the first drive so I purchased the Seagate FreeAgent...Go. But it didn't recognize it either?? So it's beyond me. If you need additional info I can provide it.
