I did some test today with another USB drive. Here are the results : From Linux (NTFS) $ dd if=FreeDOS-1.1-memstick-2-2048M.img of=/media/ben/MD/FreeDOS-1.1-memstick-2-2048M.img 3948544+0 enregistrements lus 3948544+0 enregistrements écrits 2021654528 octets (2.0 GB) copiés, 91.5862 s, 22.1 MB/s

Would a more recent NTFS-3G help ? Currently using 2012.1.15AR.8 from SFE.

I don't remember when the disk used to be NTFS, 1 or 2 years ago. I had to reformat it for compatibility issues with shiny hardware I don't manage. I'll try to reformat it to NTFS and see how it goes. Best regards.

Maybe just a matter of block size in this case. Also make sure that USB2 is actually used, I found Solaris/illumos to fallback to USB1 on several occasions.
