and got "e2label: Bad magic number in super-block while trying to open
/dev/sdb
Couldn't find valid filesystem superblock."
fdisk -lu shows
Device Boot Start End Blocks Id System
/dev/sdb1 * 128 3915775 1957824 b W95 FAT32
Partition 1 has different physical/logical endings:
phys=(242, 254, 63) logical=(243, 190, 11)
A search on the error message and on the output of disk turned up
several hits but they had to do with the inability to mount.
Also tried to use gparted but the label option was greyed out.
All this on a fully updated Lucid.
Any ideas?

e2label is for ext2/3/4 filesystems. This is a Fat32 file system (aka:
ms-dos filesystem), so you need mtools.
Here's a good step by step: (although, it's a bit dated, so I don't know
if there's an easier way to do this now)

e2label is for extX filesystems and fat32 filesystems don't have a superblock.

You know, one of these days I'm going to sit down and actually *read* a
man page instead of just skimming it.

You're welcome, although all that I did was point out that you
couldn't do it the way that you wanted. Two others pointed you to
mlabel...
