[comp.sys.atari.st] Disk formats

csrobe@ICASE.ARPA (Charles S. Roberson) (03/21/88)

I decided to do some quick computation to determine what I should be getting
when I format with TOS, Twister, and DCformat.  Here is what I got:

PGM		sect. siz	sects/track	tracks	sides	TOTAL
--------	---------	-----------	------	-----	-------
TOS		512		9		80	2	737,280
Twister		512		10		80	2	819,200
DCformat	512		9		82	2	755,712
DCformat	512		10		82	2	839,680

(*) DCformat also offers the 9/80 and 10/80 sector/track combinations.

If memory serves me correctly, TOS usually reports something on the order
of 736,xxx bytes availble for use, so I assume some of the storage is going
to overhead.  What about totals that I gave in my earlier message that I
received from "Show Info..."?  Why are they so odd (almost literally)?

Thanks,
