The Linux installation is as follows:
/dev/hdb1 100 MB /boot
/dev/hdb2 8 MB /home
/dev/hdb3 8 MB /
/dev/hdb4 Extended partition
/dev/hdb5 1 GB Linux swap
/dev/hdb6 100 GB NTFS
I didn't know how to format an unformatted drive under Linux. I attached a firewire case with an old 12 GB Macintosh-formatted HD to my computer. In order to format it with reiserfs, I used Yast2. I had to go to expert mode and rewrite the partition table. By this action Yast2 puts an entry into the fstab, that I modified to:
/dev/sda1 /media/firewire reiserfs noauto,user 0 0
since I don't want to have it connected every time I boot up. Instead I can now mount it as a regular user manually with:
mount /media/tmp/
