Whilst working on a SB1 application recently, the device was disconnected by Windows during copying of files. This seems to have corrupted the UserDrive file system in some way and I now cannot write any files to it at all. Is there any known way to fix this or will I need to repartition the UserDrive on the device? I've attached a screenshot below of the error that Windows Explorer returns during attempting to copy a file.
 

 
I have already tried running chkdsk on the filesystem with no luck.
