Hi there,

I am running Ubuntu 11.10, I want to backup some files to an USB 3.0 hard drive, but my notebook does not have 3.0 interface, so I plug in an USB 3.0 Express card, but unfortunately the system does not recognize it at all, so I've to do it on a 2.0 port. My USB drive is almost full so I removed some files and they gone to the recycle bin, but I could not add more file to the USB drive I've to empty the bin first, but after retry many times the system still unable to empty the bin, there is no error message the system just give up doing this, end up I've to format the USB drive to clean it up, what's up in here !?

Did you say you've reformatted it? Is there still an issue? If not, are you just looking for an explanation, then?

If you are still trying to solve the problem, perhaps try finding the files and 'rm'ing them as root - if you can't, you should at least get an error message which will give us a clue as to what's going wrong.

Yes I reformatted it, I just remember I could do a fsck but does it work on USB ??

If you've reformatted it, then you should have lost all your files and the trash, so the problem should be sorted. However, yes, you can run fsck on a USB stick as far as I recall.
