I am using a 12.04 64 bit version of xubuntu and whenever i try to copy files from my computer to any usb drive, it starts with a good speed and comes almost to an end very fast but as soon as it reaches and starts showing "1 second remaining" it just stuck and sits like that for minutes and do nothing, no response at all, and then suddenly the file copy gets completed successfully. So why this problem occurs is anyone having a solution for that?
I have also uploaded the screen at which it get stuck, the screenshot is without the string "1 second remaining" but the same occurs with the string visible on the progress bar. The screenshot is taken when i tried to copy a file of almost 900 mb to my usb drive. The problem doesn't occur when copying small files such as of few kbs or so.
