Hm, strange.
Here’s parts of my /etc/mtab
/dev/sdb1 /share/hdd/data ext3 defaults,usrquota 1 1
/dev/sdb2 /share/hdd/conf ext3 defaults 1 1
/dev/sdb3 swap swap defaults 0 0
/dev/sda1 /share/flash/data ext3 defaults,usrquota 1 1
/dev/sda2 /share/flash/conf ext3 defaults 1 1
/dev/sda3 swap swap defaults 0 0
sdb is port 1, and sda2 is port 2. Incidently, this matches my drives.
And, its just 2 partitions that the linksys firmware creates.
The third one is swap, which is futile on a flash drive anywho 😉
