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
