No, just DON'T use "High density" diskettes.
If you can find them, use diskettes rated for 720K usage.
If you CAN'T fine them, use 360K diskettes. Most of us have no problem
with using 360K diskettes, but SOME (including Tony) have had problems
with them. That might be due to his closer geographical proximity to
Stonehenge, or to the Greenwich meridian :-)
Erck. That distant splash you just heard was the
sound of Doc hitting
the bottom of the well. We passed the "All Greek To Me" phase awhile
back.
Sorry; some of the issues that came up do NOT matter for what you want to
do.
So. The "fd0h720" device on my Debian
Linux machine is defined as
"/dev/fd0h720 5.25" 720K in a 1200K drive"
Perfect!
Will the 1.2M drive write reliable QD disks? Note
that I said "write
reliable" not "reliably write". Several tries is no biggie.
Yes!
(with the right blanks)
360K (AND
"QD") is 300 Oerstedts; 1.2M is 600 Oerstedts.
Uh. OK. In dumbass
terms, does that mean "no go"? No, dd doesn't care in the slightest what the
file structure is. I've
imaged disks with filesystems totally unknown to Linux with dd.
Perfect!
Blocksize is sometimes an issue, but I've found
that setting blocksize
to "1" fixes that just fine.
Or, if I had a copy of 22disk (yeah, I'll google
in a minute) I
suppose I could boot to DOS and do that. Does 22disk understand dd
images? (Andreas already cut to the chase & imaged a couple of trial
runs for me)
It should be able to do it without any problems.
If not, contact me off-list and I'll help you.
