This is a problem that's been bugging me for months at home and has now "spread" to my work computer as well somehow. I have 2 USB drives, both Kingston - 8gb and 16gb. At home, I can plug the drive in, see it in Explorer, and view contents. I can also copy files from the drive to my system hard drive. I cannot copy files to it however. When I attempt to, it locks up for several seconds and then tells me that it can't find the specified file (which I know is there). Explorer then restarts and the drive is no longer accessible without unplugging it and plugging it back in. If the drive is formatted as NTFS, that problem is replaced by neverending "Delayed Write Failed" errors instead.
At the office, things were fine until I formatted the drive as NTFS to let me copy files >2gb. Then I got the lovely Delayed Write Failed messages. I moved it back to FAT32 only to have the *exact* same symptoms as as home. I can copy from the usb drive, but not to it.
I can plug the drives into someone else's computer and they work just fine and dandy.
I've tried any number of potential fixes found on the net (some here) but none have remedied the problem. The last promising lead I had concerned the drive somehow being made read-only but I could not find information on how to check that for XP.
General system specs:
home - quad core phenom, 4gb ram, amd mobo, all drivers up to date
office - dual core intel, 2gb ram, asus mobo, all drivers up to date
For what its worth, all other usb devices work fine, including printers, mice, keyboards and gamepads as well as the Verizon wireless modem I use at home for internet.
