I have 4 identical disks on it and they show up as /dev/sda, b, c, and

However, sdb needs to be replaced.  How can I tell which drive is sdb?
Is there a way to identify what drive is what?

Sometimes you can infer from dmesg.  E.g., type "dmesg | less" then
scroll until you see where sdb is initialized; it might show the model
and serial number of the drive.

Another approach is to use smartctl, i.e.: "sudo smartctl -a
/dev/sdb".  This will definitely show you the model and serial number.
 You can also use hdparm for the same effect: "sudo hdparm -I
/dev/sdb".

I'm sure there's more ways, but those are the first that come to mind.
