11 hard drives, which ones are 8MB cache?

[ShowdOWN]

I just received 11 WD 120 GB hard drives here at work and i need help figuring which ones are the 2MB cache and which are the 8MB cache drives.

ive tried to analyze them for any differences but they seem to all look the same except for the manufacturing date.

can anyone tell me if there are any distinguishing marks that tell them apart?

any help will be appreciated.

thx

The 8MB ones will have a "JB" (Jumbo Buffer) at the end of the model number.
