thanks givre for your reply
the only partition in my fstab is the windows partition, no usb drive is listed there...
Code:# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/sdb1 / ext3 defaults,errors=remount-ro 0 1 /dev/sdb5 none swap sw 0 0 /dev/hda /media/cdrom0 udf,iso9660 user,noauto 0 0 /dev/hda1 /media/hda1 ntfs-fuse auto,gid=1001,umask=0002 0 0
however, i seem to have found a way to make all usb harddrives ready with read/write permissions.
i had to start windwos xp, connect all usb drives and then restart the pc, this time booting ubuntu (without disconnecting the drives). oh wonder! all drives are present and i can read them and write onto them.
of course i have absolutely no idea why this is the case. i just hope it'll stay that way
