I'm playing IDE drives for a Z80 or maybe 8085 project...
This means any discussion of PC BIOSs or PC OSs will be summarily ignored.
This is not about the physical interface.
The file system is not relevant to this, I plan to format the drive to
meet my
wishes.
First off I know that most drives over 2gb supported LBA so this covers
drives smaller.
What I need to verify or know is what drives smaller than 2GB or better yet
smaller than 1GB that support LBA. I don't want to use CHS and while I can
that means I have to write my own LBA to CHS and sine I may also use SD
and CF it would be nice to stay in LBA all the way.
Its handy of the drive looks like n-many 512byte blocks starting from zero.
So what smaller drives support LBA? The drive can be 3.5" or 2.5"
format.
I have a large (greater than 50kilos) collection of IDE/ATA interface
drives
from 20mb all the way to 4.3GB (larger is not being
considered) to pick
from.
I think but can't verify that Seagate ST3660A, 545MB (the fixed one)
does LBA.
the question is what others?
Obviously I'd like to use up a smaller drive, just because, no good reason.
I want to do a bit of playing with OS creation or heavy modification.
