1 I have a USB stick with a crucial file on it (and only an old backup
2 elsewhere). It's formatted NTFS because I wanted to be able to open
3 the file on various Gentoo systems and my research indicated that NTFS
4 was the best solution.

6 I decided to copy a 10GB file from a USB hard disk directly to the USB
7 stick this morning and I ran into errors so I canceled the operation
8 and now the file manager (thunar) has been stuck for well over an hour
9 and I'm getting errors like these over and over:

41 nmon says sdc is 100% busy but doesn't show any reading or writing. I
42 once pulled the USB stick in a situation like this and I ended up
43 having to reformat it which I need to avoid this time since the file
44 is crucial. What should I do?
