use e2label with the device name followed by the new name
for example, to change the device sda1 to foo, do:

e2label /dev/sda1 foo

Technically, e2label is labeling a file system, /dev/sda1 is a file system.

But you are mentioning a harddisk, this would be /dev/sda - if you do want to label a harddisk then you cannot do that with e2label.

You can set the File System Volume label like this:
# tune2fs -L samba /dev/sda1

To show the name:
# tune2fs -l /dev/sda1
tune2fs 1.42.5 (29-Jul-2012)
Filesystem volume name:   samba
...

How do you display the current name of your harddisk?

It is showing as

Disk /dev/sdb: 536.9 GB, 536870912000 bytes

Gerwin Jansen, EE MVETopic Advisor Commented:
/dev/sdb is the harddisk, you cannot label that, but a file system (or partition) you can, so for example:

# tune2fs -L YourLabelHere /dev/sdb1

Which command did you use to get the above information?
