Hi All, thansk for the information so far... certainly helps!
>>What I'm after is "logical" info, that is the layout a programmer would
use.
>>I am thinking that the D9090 is laid out as: 918tracks (1-918), 32 sectors
>>(0-31). etc.
>Model D9090 D9060
>heads per drive 6 4
>formatted storage
>capacity per unit 7,47Mb 4,98Mb
>cylinders(tracks) 153 153
>sectors/cylinders 128 192
>sectors per track 32 32
>blocks per sector 256 256
I'd seen this info, and hence my confusion.. the work "cylinders" in two
lines. By "logical" I was refering to what the programmer would use when
they sent a U1 or U2 command. Come to think of it... do these drives support
U1, U2 or do they need B-R and B-W???
>> Can someone confirm this, and also the layouts of the other drives

>Which era? The era of 5MB-10MB 5.25" drives? The entire list of
I was thinking this era in Commodore's history... for example the CBM 8250
etc rather than specific mechanisms.
Many thanks, Nick
