Note that fdisk would only show the partition type value, not the
actual fs.
"parted /dev/sdb p" tries to detect the fs type.
root@pegasus ~> parted /dev/sdb p

I also ran the following fdisk commands:

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

What I'm trying to do is take a Western Digital external 2TB USB-ported
drive and change its label from "My Passport" to something else.
I can do it on my Windows 7 laptop in Windows Explorer. I would like to be
able to do it at the command line.
I can use fatlabel for SD flash memory cards; it produces the following
error when I try to do it on my F27 laptop:
root@pegasus ~> fatlabel
usage: fatlabel device [label]
root@pegasus ~> fatlabel /dev/sdb MYDISK
Logical sector size is zero.
root@pegasus ~> fatlabel /dev/sdb1 MYDISK
Currently, only 1 or 2 FATs are supported, not 0.
fyi,
MP
