hdparm is a nice tool for IDE drives on an IDE chain. For example:
$ hdparm -I /dev/hda

Unfortunately, I have not found anything similar for SCSI drive, which
is what IDE drives become when attached via USB or Firewire. One could
use a few different commands with SCSI. For example, this was run on my
laptop:
# scsi_info /dev/sda
SCSI_ID="0,0,0"
HOST="0"
MODEL="ATA FUJITSU MHV2060A"
FW_REV="0000"
# hdparm /dev/sda
/dev/sda:
IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 7296/255/63, sectors = 117210240, start = 0
# cat /proc/partitions | grep sda
8 0 58605120 sda
8 1 56195338 sda1
8 2 1 sda2
8 5 2409718 sda5
One could also check dmesg right after one plugs in a drive. One could
also run 'dd if=/dev/sdb of=/dev/null' and watch for any read errors.
