Ok, so here is my problem; I cannot copy files from my usb flash drives onto my PC anymore, I keep getting error message "cannot find specified file". I have 2 flash drives and they both seem to work on other computers. I can copy files onto them just not back onto my PC, OS is Windows XP and it is an older Dell optiplex. This just started about a month ago, prior to that I didnt have any problems copying from the flash drives. I'm guessing that its probably some kind of hardware failure, but I'm hoping its not. Anyway, any advice will be appreciated!
