I can't get anywhere. I have a 160 GB pushbotton external hard drive, seagate brand, connected with a 2.0 USB. It worked fine, then all of a sudden when I tried to open it all I got was an I/O device error. At first people told me this was a registry problem, but when I tried plugging it into other systems the same error popped up. Strangly, the drive used to read E, but now reads as G. I don't think this is entirely the cause of the problem though, because when I tried plugging this into other systems it read E, but still with the same I/O device error. I have Windows XP on an HP notebook, and I am clueless. I tried disabeling the device, re-enableing the device, uninstalling the device and reinstalling the device. I tried a registry cleaner but it only cleaned 50 problems. I purchased a new cable and that didn't work either, and plugged both cables into all 4 of my USB ports. Is there a solution? Does any one know what an I/O device error means? Can I retrieve my information? I'm willing to drive very far and buy very expensive software to do this, so please tell me if there is any software that can help. Also, please tell me if there is any basic thing I can do to help.
