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. > I found this article which mentions an experiment with ext4 fs. Thanks for the link you sent in your other mail and thanks for pointing all this out :-) Sincerely, Rainer
