No errors.

"lsusb -tv" showed the stick to be USB 3.0.

Since the USB sticks  contain symbolic links  and have to  be accessible
from both,  Linux and Windows they are NTFS formatted,  and according to
"mkntfs(8)" the sector size can be at most 4096,  while the cluster size
is limited to 2097152, that is 2G.  However, when NTFS formatting an USB
stick from within TrueCrypt/VeraCrypt or directly in Windows the maximum
cluster size  is 64K,  with the  only difference  that Windows  calls it
"allocation unit size".

So I think above you were talking about  128K clusters rather than sect-
ors.  I'll give that a try  and will reformat  the USB sticks  using the
maximum cluster size of 64K.   But I don't see a way to "align" the file
system on these USB sticks.

Thanks for the link you sent in your other mail  and thanks for pointing
all this out :-)
