my USB harddisk Maxtor 3200 has suddenly started malfunctioning in Windows 7. It isn't recognised (and says so) in any of the USB2.0 ports. It does however work in my keyboard USB1.1 slot!
I have updated chipset drivers, updated Windows, reset CMOS, loaded optimized defaults etc etc.. but no joy.
I have plugged it into my laptops USB2.0 slots and they work fine. I then ran Seagates diag proggy on it and it returned with no errors. Seems to be my PC, although USB2.0 wireless dongle works fine. I have dual boot Win 7 and Vista, and Vista has the same problems so I'm thinking this is more than just the OS. But why would it work in USB1.1 and not USB2.0? I have like 10 or so USB2.0 ports on various parts of the PC, both attached on the mobo and seperate powered hubs e.g. my Dell monitor.
Any suggestions? I'm a bit stumped. I could try a windows restore if anyone thinks its worthwhile. . . thought I'd ask you lot first

Jim: Personally I'm not bothered if someone says they can run Crysis on their calculator, so don't even think about trying to drag me into this.
