An example of a non-PC format 5.25 inch disk that normal drives can read would be the DEC
RX50 floppy, which has 10 sectors per track rather than the PC standard 9 sectors. But a
standard drive will read and write those just fine, if it's told to use that format.
I did that ages ago in DOS, but in the past 15 years or so I've only used Linux for
that job. It's a simple matter, you just need to know what the format is.

Hi,
n00b alert
Does anyone have a 101 level boot strap guide for someone wanting to get
into creating better-than-dd disk images?
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.
If they are 5¼ & 3½ inch disks which are not copy protected and are
readable with standard PC compatible floppy controllers, but not
necessarily limited to standard DOS formats, and you had a older PC
with a floppy controller which you could set up to boot into real mode
DOS, I would start with Dave Dunfield's ImageDisk program.
