There is a version 1.2 of spintest which is more accurate than
whatever the (unidentified) version was/is. It is also larger (over
3 kbytes) because a lot more verbiage is included explaining
interleave and interleave-testing.

I personally formatted a drive at 2:1 interleave, ran the earlier
spintest and was told it was a 3:1 interleave. Version 1.2 reported
the correct 2:1 interleave factor.

By the Way - spintest doesn't report the interleave factor for my
CDC Wren IV SCSI drive, but it does report the bytes transferred
per second: 1044,480 (!).

  The summary says it all - how about posting the newer version?

Excuse me, but SPINTEST doesn't report the interleave. It reports the
number of revolutions it took to read a track. These are not the same thing.
If you have a version that *does* report the interleave, I'd like to get a
copy.

He's right - SPINTEST reports the number of revolutions to read a
track. I took the assumptive leap of faith that these are the same
I'll go off to my corner to think about why they are or aren't
the same...

Somebody asked me to post the newer version of SPINTEST. When I
determine that it's "freely distributable" I'll send it to Rahul
for posting.

....  [Kenn may have confused revolutions per track with interleave]
  

Kenn: Please post this newer version of spintest with the moderator. 
      Many of of us would be interested in a program which reads 
      interleave directly.

Leonard: Please email me on method of converting revolutions per
         track to interleave ratio (unless you have other requests,
         in which case post to c.b.i.p.d.)
