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.
