I have Windows 7 Pro 32 bits, attempting to copy large files (over 1 GB) from one of my external USB drives to another does not work. Same thing from the USB drive to the pc drive. The file transfer starts and then quickly slows down to a crawl and then sits there for hours.
Files less than 1 GB transfer fine. With or without my antivirus, no difference. I've also tried disabling remote differential compression, no change either. And ditto for TeraCopy, same exact thing.
