drive label sticker = ST1181677LCV bios reports ST1181677LC

the sticker on several barracuda 180's i have indicates: ST1181677LCV -
however the scsi bios indicates these drives are really ST1181677LC -
and subsequently the 4mb data-buffer versions rather than the 16mb
data-buffers.

on linux i'm using the excellent sg3_utils. but i don't see any tool
that would indicate data-buffer size on the drives. is there such a tool
that will reveal the drives data-buffer?

thx

exhaustive search FTW.
looks like sg_test_rwbuf -q /dev/sg? will do the trick.
