I have a USB stick with a crucial file on it (and only an old backup elsewhere). It's formatted NTFS because I wanted to be able to open the file on various Gentoo systems and my research indicated that NTFS was the best solution.
I decided to copy a 10GB file from a USB hard disk directly to the USB stick this morning and I ran into errors so I canceled the operation and now the file manager (thunar) has been stuck for well over an hour and I'm getting errors like these over and over: [ 2794.535814] Buffer I/O error on dev sdc1, logical block 2134893, lost async page write [ 2794.535819] Buffer I/O error on dev sdc1, logical block 2134894, lost async page write [ 2794.535822] Buffer I/O error on dev sdc1, logical block 2134895, lost async page write [ 2794.535824] Buffer I/O error on dev sdc1, logical block 2134896, lost async page write [ 2794.535826] Buffer I/O error on dev sdc1, logical block 2134897, lost async page write [ 2794.535828] Buffer I/O error on dev sdc1, logical block 2134898, lost async page write [ 2794.535830] Buffer I/O error on dev sdc1, logical block 2134899, lost async page write [ 2794.535832] Buffer I/O error on dev sdc1, logical block 2134900, lost async page write [ 2794.535835] Buffer I/O error on dev sdc1, logical block 2134901, lost async page write [ 2794.535837] Buffer I/O error on dev sdc1, logical block 2134902, lost async page write [ 2842.568843] sd 9:0:0:0: [sdc] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE [ 2842.568849] sd 9:0:0:0: [sdc] tag#0 Sense Key : Hardware Error [current] [ 2842.568852] sd 9:0:0:0: [sdc] tag#0 Add.

I once pulled the USB stick in a situation like this and I ended up having to reformat it which I need to avoid this time since the file is crucial. What should I do? - Grant
