My Lubuntu machine is changing the way it designates the hard drives every time I change /etc/fstab and reboot it. For example, if I have the definition below the /media/WD2Tb and /media/Elements4Tb drives are not mounted:
/dev/sda1 /media/Samsung2Tb1 ext4 defaults,nofail 0 0
/dev/sdb1 /media/Hitachi2Tb ext4 defaults,nofail 0 0
/dev/sdd1 /media/WD2Tb ext3 defaults,nofail 0 0
/dev/sdg2 /media/Hitachi3Tb ntfs defaults,nofail 0 0
/dev/sde2 /media/USB4Tb ntfs defaults,nofail 0 0
/dev/sdc1 /media/Elements4Tb ntfs defaults,nofail 0 0
(The first 4 drives are internally mounted. The last 2 are external USB drives).
When I look at the disks in settings I see that the WD2Tb drive is designated as /dev/sdc1, and the Elements4Tb is designated as /dev/sdd1. So I edit /etc/fstab to change it to this:
/dev/sda1 /media/Samsung2Tb1 ext4 defaults,nofail 0 0
/dev/sdb1 /media/Hitachi2Tb ext4 defaults,nofail 0 0
/dev/sdc1 /media/WD2Tb ext3 defaults,nofail 0 0
/dev/sdg2 /media/Hitachi3Tb ntfs defaults,nofail 0 0
/dev/sde2 /media/USB4Tb ntfs defaults,nofail 0 0
/dev/sdd1 /media/Elements4Tb ntfs defaults,nofail 0 0
...but after a reboot the /media/WD2Tb and /media/Elements4Tb drives are not mounted again. This time when I look at the Disks in Settings I see that the WD2Tb drive is now designated as /dev/sdd1, and the Elements4Tb is designated as /dev/sdc1 (which is how I had them defined in the first place).
I can repeat this process ad infinitum - whenever I edit fstab, revert the designations of those two drives, and reboot the designation of the drives reverts back to its previous value. If I reboot without editing fstab then the designations stay the same. So it's basically whack-a-mole.
I know that the designations are arbitrary, but I don't understand why these two drives are having their designations changed whenever I edit fstab and reboot, despite no changes being made to the hardware.
