Answer

Maybe

If you have IDE drives, you won't need to adjust fstab for other drives.

If you have SCSI drives, it depends upon which drive you removed and how you identified it in fstab. Linux assigns /dev/sda to the first SCSI drive it sees, sdb to the second, and so on. If you remove the drive that was sdb, the drive that was sdc will now become sdb, and you will need to edit fstab if you reference /dev/sdb there. If you used labels instead of device names, no change is necessary.

See "man fstab"

Other drivers (FC) may also change if you remove a device.

Just for the reason of changing device names when adding/deleting disk
drives, current recommended practice is to use and refer to disk labels
within fstab.

Yes, that's why the last sentence was " If you used labels instead of device
names, no change is necessary."

Nowadays most distros use UUIDs by default, so you may want to add a little
hint that /dev/[sh]d* is used to reference disks.

I think you just did :)

I agree with your "literal" comment.

The problem I have with these is that Linux changes so quickly and sometimes
quite drastically. Many of the questions are out of date and don't apply
today. I do try to do updating, but mostly I rely on comments like yours.
