While copying 11GB of files on my desktop FROM external HDD it was okay, but when I connected my 16GB usb-flash drive and started copying files TO flash-drive, it began to suddenly freeze and unfreeze. First 30% of so seemed to be okay, than it froze, after a few minutes the process continued. Then it came worse. At the point of last freeze on 98-99% I had to wait around 7 minutes before it continued. I couldn't also use any tools on my desktop or within opera broser. Cursor was moving but with no effect on clicks.
Had someone similar problems? Is there a way to fix it?
