Richard:

On most Western Digital Caviar hard drives, you can tell
the cache size from the Model Number.

The model number is located on the hard drive. There will
be a hyphen, then some more numbers. The LAST letter
is the code for the cache size:

Letter  Cache Size
--------        ---------------
   M          32K
   F          64K
   H        128K


I believe the newer Caviar hard drives have 256K cache.

You can also get the information from software that
queries the drive but, apparently, you have nonesuch.
