A more practical modification would be to use a 600
rpm drive (which re
not uncommon for 3.5" disks) and add a second read amplifier. Then you
could read both sides at the sime time, thus meaningyou could image the
disk in 80 revolutions. And it's turning twice as fast, so I could guess
you'd be close to 1/4 of the origianl time.
But does it really matter? This is the sort of thing where you put a disk
in and let it image it, then put abnother disk i, and so on. You can be
doing something else while it's imaging the disk, when it finishes, you
can pop anotehr disk in when it's convenient.
Yeah.
What's the hurry?
45 seconds added to the physical read time does not seem very onerous. It
might be a little faster if the tracks are converted one at a time,
starting while the drive is stepping/settling.
OK, if you have a LOT to do, invest in a automatic disk loading drive
(commonly used for small production duplication)
