....now have 1 TB yeah!
It is my 3rd SATA drive in this box. All is well, but I am puzzled.
Before the new drive was added I had windoze on sda, F9 on sdb, grub on sda.
When I booted the 1st time after adding the 3rd drive, gparted showed the new drive as sda, windoze as sdb, fedora as sdc. grub.conf reflected things as they were before. After formatting the new drive as a linux partition, I was hesitant to reboot without editing grub.conf to reflect the new designations as reported in gparted.
I did not change the conf file and all is booting with no issues.
Why does grub function under these circumstances? (Not that I am complaining)
