I've 5 HDD and, of course, I can not put all them on my PC. So I've purchased 2 USB2.0 mobile storage system for use those HDD on my USB port. Of course the HDD doesn't work. When I plug one HDD on USB, on my PC appear the peripherical icon but a few seconds later a message error was showing and tell me that there was a problem on the install the USB device. If I plug the HDD on IDE it works fine. So is not a HDD problem...is USB that doesn't work properly. I've already update the intel chipset but nothing change. Could someone suggest me something?
