I tested attaching another disk to QNAP, a disk that happens to have an 
earlier backup of the same CD FLAC rips... the same problems show there, 
ie. 10 unaccessible sequential (ls -U) directories under that 
subdirectory. Different directories this time, so it's not about the 
contents, but some other feature / index of those. Also on the same disc 
are a few other unaccessible directories, but that's the only directory 
with so many subdirectories that the "10 in a row" thing is visible.
