I own the retail versions of TI 8, 10, and 11, and I can't get them to recognize some of the external USB hard drives I own. I've tried a 2.5 inch 160gb Toshiba hard drive, a 2.5 inch 160gb Western Digital hard drive, both of them USB powered and a 3.5 inch Seagate 160gb external drive with its own power source. I've tried a Y-cable that allows you to draw power from 2 USB ports to hook up the 2.5 inch USB powered drives thinking it was a power problem and it hasn't helped. The 3.5 inch Seagate external drive has its own power supply and its a retail external drive not a internal drive put into a 3rd party case. Windows can see the drives just fine. But TI can't see the drives when booting from the TI CD. I only run TI from the boot CDs I don't install it under Windows. I 've seem the problem on a Intel 865 PERL Socket 478 P4 motherboard, BioStar NForce 3 Socket 754 AMD Athlon 64 motherboard and a BioStar P4 motherboard with VIA chipset. None of these machines is overclocked. Strangely enough I also have a 2.5 inch USB powered 250gb Seagate external drive that TI will recognoze without using a Y-cable. Is there some difference in the USB chipsets these external drives use that causes TI not to recognize them? Does TI 2009 fix this?
