The HP150 could use a 5.25" drive (HP82901, for example). The disks were
not IBM PC format (they were 35 cylinder for on thing), but at least they
used noraml MFM encoding and could be read at the sector level on other
machines.
The Sirius ws just plain strange. Variable speed drives (so if put in a
normal drive, the bit rate varied between cylinders), GCR encoded.

Victor/Sirius 9000 had the least compatible
MS-DOS disk format.
I dunno, I think the 3.5" disks on the HP 150 that came out in 1983
were less compatible, since everything else was still doing 5.25. :-) >
