#################################### 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

/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% /

/dev/sda3     ext3    615G  146G  439G  25% /other

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