[obligatory offering to non-existant bug]

Long, long ago, in a galaxy far, far away, there was a world which used single 
density 8" diskettes.  Then along came better technology, and lo, there was 
double density 8" diskettes.  But existing boot roms didn't know how to read
double sided diskettes, so OEMs began mixing the format of their disks, using
single desntiy for the boot tracks, and double density for the rest of the 
disk.

So a question comes up:

In DOSland, is there a significant number of OEMs still using mixed density
8" disks?  For that matter, has anyone ever come across mixed density
mini-flops?  And finally, on a slightly different subject, has anyone noticed
any floppy formats on double sided diskettes on which the track numbering is
other than "down the cylinder" (track 0 is on hd0, track 1 is on hd1, track 2
is on hd0, cylinder 1, etc)?

I am interested in any information relating to the above.

thanx in advance!
