|I got a new WD1006V-SR2 to re-format Micropolis' 71Meg(1335) and 34Meg(1323).

You can customize the geometry, it's an entry on the menu you get when
you run cc00:5.

|I ran SI on C:, and the index is 3.6, compared with 2.7 in MFM 3:1 case.
|I also did CORETEST.  The transfer rate now is 672 KB/sec, while it was
|162 before.

Did you set 1:1 interleave? You should get about 798 Kb/s.
