6.2x is my favorite version of DOS, "the first one where improving
reliability was a fundamental intent", and 3.20 was the first one that
consistently had 720K DOS format, however,
since imaging software would most often be using INT13h, or even direct
acccess of the FDC, ANY version of DOS should be OK.
Life is sometimes a little easier using a 720K 5.25" drive (such as
Mitsubishi 4853, Shugart 465, Tandon TM100-4) instead of a
1.2M 5.25" drive.
If the drive is running 300RPM, then the data transfer rate should be
If the drive is running 360RPM (some 1.2M drives), then the data transfer
rate should be 300K.
But correcting the data transfer rate is all the extra that is needed for
using a 1.2M for "720K"/"quad density" formats
