     I currently have a Trumpcard 500 w/ a Seagate ST-157N-1 48 meg drive.
I just purchased a ST-296N 84 meg drive that I am chaining to the card
as well and have some formatting questions.
     Originally, with the ST-157N, the Trumpcard utilities program formatted
it with a capacity (# blocks) = 93000
      and # of cylinders      = 598 approx..
 

     Someone w/ the same setup noticed that the ST-157N specs showed the
capacity to be 94860 with 607 cylinders, and suggested I format my drive
as such and get an extra 1/2 meg or so....It worked like a charm.
(one VERY odd thing was that when I told the program the drive had 607
cylinders, it recognized only 606....when I changed it to 606, it only
recognized 605.  Therefore, I put it back to 607, and it formatted it with
606 and works like a charm to this day.)
     Anyways, to get to my question.  The ST-296N has the same problem in the
Trumpcard utilities.  The program lists the ST-296 as having:
     Capacity (# blocks) = 160,140
          # cylinders    = 785
  
     Seagate drive specs for the 296N are 165851 blocks.  Well, I'd like
to format the drive w/ the Seagate specs and get the extra space, but I
don't know how to figure out the number of cylinders to go along w/ it.
     Cross multiplying gives me an approx. figure of 813 cylinders....
Is this correct?  If somebody can offer a solution or suggestions, I'd 
really appreciate it.
                                       Thanks,
                                        Jason
