I left the US_FL_FIX_INQUIRY and US_FL_IGNORE_RESIDUE. What I have done in this log: I plugged the key (it was detected, and sda1 was found). I mounted sda1 (line 258), copied some files, unmounted sda1 (manually), re-mounted sda1 (line 2410) without unplugging the key and had a look at the files (reading only, no write operations). One file was corrupted, others were fine. Btw, how can I know the maximum number of sectors (max_sectors) a device can accept ? -- Grégory SCHMITT <mailto:[EMAIL PROTECTED]>
