- Hi guys ...
-
- My own experience says - allthough it might be provocative - to say that a
- disk has allways 64 heads and 32 secs/cyl. The advantage is that the
- number of cylinders equals the number of formatted MB's. Since the net'
- MB's are allways given it should be no problem to determine the number
- of cylinders (each of size 1 MB with those parameters). Nevertheless it might
- become hard to determine the exact nr. of cylinders due to some mystic
- behaviour of Solaris @.#.%.. Try some binary search (1020 .. 1000 .. 1010
- .. 1015 .. 1013). This is my own way of doing. If someone knows a better one ...
-
- PLEASE: Please mail ... no follow up's ...
