Summary: Best to not use ST-225 w/RLL


Right you are.  It is best not to use the Seagate ST-225 with an
RLL controller card (insert your favorite brand).  The ST-225
doesn't promise to have plated media, plated being better for the
higher bit density of RLL than standard oxide media.  A brochure
from Seagate also claims that the electronics of the ST-238 have
also been "optimized" for RLL 2/7.-- although that probably isn't
anything more than a trim pot set to a slightly different value.

Rumor has it that ST-225s currently appearing on the market really
are 238s, but just have not undergone the level of testing
necessary to certify as a 238.  What can I say, you pays your money
and takes your chance if you use a 225 with RLL.  A 238 is only
about 50 bucks more than a 225, so I opted for the 238 on my own
computer.
