#################################### question ####################################

I have selected the sata drive to be the default boot device (and it always does -good so far-)
The uuid's in grub.cfg match "ls /dev/disk/by-uuid -lh|grep sdxy" where x=a,b,c,d y=1,2,3,4

My problem/bug? is that sometimes the *labels* of sda & sdc switch places in "fdisk -l" and "df -hT." I say *labels* only because I recognize the partition sizes.

Right now df -hT spits:
Filesystem Type Size Used Avail Use% Mounted on
/dev/sdc1 ext3 9.9G 4.8G 4.6G 51% /
none devtmpfs 874M 348K 873M 1% /dev
none tmpfs 878M 1.5M 877M 1% /dev/shm
none tmpfs 878M 88K 878M 1% /var/run
none tmpfs 878M 4.0K 878M 1% /var/lock
none tmpfs 878M 0 878M 0% /lib/init/rw
/dev/sdc2 ext3 291G 83G 194G 30% /home
/dev/sdc3 ext3 615G 146G 439G 25% /other

And some other times spits:
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 ext3 9.9G 4.8G 4.6G 51% /
none devtmpfs 874M 348K 873M 1% /dev
none tmpfs 878M 1.5M 877M 1% /dev/shm
none tmpfs 878M 88K 878M 1% /var/run
none tmpfs 878M 4.0K 878M 1% /var/lock
none tmpfs 878M 0 878M 0% /lib/init/rw
/dev/sda2 ext3 291G 83G 194G 30% /home
/dev/sda3 ext3 615G 146G 439G 25% /other

Do you have any idea as to why and how to correct it? Thanks in advance.
