Commodore 1581
<storage>
Commodore Business Machines's 3.5 inch
disk drive for the
Commodore 64 and
Commodore 128.
The drive stores 800 kilobytes using an
MFM format which is different from both messy-dos 720 kb, and the
Amiga 880 kb formats.
The 1581 supports a poor imitation of directories which are really just partitions and largely unused.
It also supports burst loading like the
Commodore 1571, but is actually faster as it is better designed.
It has 3160 blocks free when formatted.
The 1581 is the highest density C64 serial bus drive made by Commodore.
However Creative Micro Designs (CMD) make the FD2000 (1.6MB) and (until recently) the FD4000 (3.2MB) 3.5" disk drives.
GEOS users like 1581s as they are very fast when used with GEOS.
