Re: [opencbm-user] How-to Rip a CP/M-formatted 1581 Disk to a .D81 Image (???)

[Myke C. <Adm...@My...>]

One other lesson I learned along the way:

After the 1571 attempt had failed and I resigned myself to using 1541 
format for this breakdown / reassemble process... my instinct was to use 
FORMAT.COM's "C64 Single-Sided Disk" option because I really didn't know 
what a "C128 Single-Sided Disk" even is.  But I found out.

I know that in CP/M, a freshly-formatted 1571 disk has 336k free.

So I was surprised to see only 129k free after having formatted a disk 
using the "C64 Single-Sided" option.  I went with it anyway... only to 
find "Big Blue Reader 128" doesn't recognize that format.

By that I took a clue that the difference between "C64 Single-Sided" and 
"C128 Single-Sided" disks is... the C64 format uses GCR which the 1541 
understands.  The "C128 Single-Sided" format uses MFM which "Big Blue 
Reader 128" recognizes without issue.

So after reformatting all of those disks one more time as "C128 
Single-Sided" disks... the planets aligned and harmony filled the universe.
