Because, very likely I should re-learn and re-do all I can do with Debian, re-write many howtos and packages installations. Hard long work.

I see, thanks. Maybe the problem might be worked out if I could change the old pen's device into sda as well? I noticed that my old pendrive can only be mounted as /dev/sda1, whereas the new one indifferently with /dev/sda or /dev/sdb. If both pendrives had the same device then I could put just one entry in fstab and the plugging order would not be very important. I do want to use both, but one at a time. Is there a way one can change /dev/sda1 into /dev/sda or /dev/sdb for the first pendrive? Cheers, Rodolfo -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
