Hi -

This isn't strictly on charter, so I hope people don't mind.

I bought 2 IBM drives, one the DRVS-18V and the other the DRVS-9V,
18 and 9 gig 10,000 RPM drives. They didn't come with geometry info,
and I can't find it anywhere. I can find that there are 7065 cylinders,
and 10 platters, 20 heads on the 18G disk, and 5/10 on the 9. The
sector size is configurable, 512-732 bytes.

What I can't find it the number of tracks, or how many sectors per
track (assuming, say, 512 byte sectors). 

Does anyone know a way to derive this information? Or does anyone
have these drives and know? I broke down and called IBM tech support,
and they don't seem to know either, and just promised a call back which
never came.

Thanks.
