Be careful with writeback cache on removable medias!

Yes, that's right. The longname are stored in additional entries. You 
need for 13 characters one additional entry.

You can solve this problem with a larger root directory or store the 
files in a subdirectory. Or you use FAT32 (no limit on root dir).

What do you mean with halted? If you use writeback cache the kernel sync 
the filesystem automatically each 5 seconds. On slow medias (like Zip) 
that need some time if there are a lot of modified cache entries.
