How to label a disk

[Francois]

Hi,
Just got an hd failure, and I'm in the process to reinstall everything.
I plan to have a backup this time. I have here an old hd (40 giga), and
using gparted, I deleted all partitions on it. Then I recreate one
partition as shown in this screen capture :

What mean those flags (boot and lba) on the right? Do I have to reformat
everything to get rid of them ? This HD, will not be my boot disk, just
a backup I want to mount and umount during the backup process.

Something else : I want to rename that HD to "backups". I saw the
command line : "sudo e2label <device> new_name". maybe a stupid
question, but is it in my case : e2label /dev/sda4 or /dev/sda5 ??
Thank you.francois
