Just tried it right now, works here using ImgToDisk v0.24.

On RISC OS, format disk to ADFS E (800K)

On BBC Master:

Copy 800K image to 80*2*5*1024 MFM disk (MDFS, AcornDOS, ADFS D,E)
0:00 chug chug up to 1:79

Run disk sector editor, examine disk, everything copied ok. Formatting 
to AcornDOS should be the same as formatting to ADFS E, other than the 
blank filing system written to it. MDFS/AcornDOS/ADFS-E/F are all 5 
sectors of 1024 bytes, with sectors counting from 0.

The above test was with the image file on NetFS. When my PSU is repaired 
so I can use two drives, I'll do the test again from ADFS.
