I'm finding myself back in a position where I want to image / preserve
multiple 5¼ & 3½ inch disks. I think all of them are PC compatible disks.
Probably standard FAT-12 and a handful of super capacity disk formats from
the likes of IBM / Microsoft where they tried to squeeze 1.6 (?) MB on a 3½
inch disk.
I have an internal 5¼ inch floppy drive that is in unknown condition (I've
never used / tested it since I got it).
I also have (at least one) 5¼ disk that I acquired as a scratch monkey disk
to test on before working on disks that I care more about.
I was thinking about acquiring a Kryoflux in the next few months and starting
to collect better quality images of disks. I recently saw someone on Twitter
suggest that Kryoflux wasn't the best route to go and suggested a SuperCard
Pro instead.
I had been using the dd command under Linux against a USB connected 3½ inch
floppy drive for most things. But I've come to learn that's not as good as
some people would like to see preserved.
So, does anyone have a 101 level boot strap guide for someone wanting to get
into creating better-than-dd disk images?
If these were formats OTHER THAN PC-DOS, then imaging can be essential.
And, a flux-transition device, such as Kryoflux might be necessary for
some.
And, if they are copy-protected, then flux-transition imaging is
necessary, and still might not be adequate.
But, why do IMAGING on PC-DOS disks?
Why not just copy the files, and "ZIP" them?
Other than bootable or copy-protected, then re-creation is format a disk
and copy the files onto it.
In what way would "better than DD" be needed?
