It seems that Minidisk (CMS) redirects here. Maybe that isn't so bad, but it also doesn't seem right. VM(CP) minidisks can be formatted in any (or no) disk format, likely including those of OS/360 or MVS. Is there enough for an article on minidisks, separate from CMS? The reason I am wondering is discussion on History of IBM magnetic disk drives which leaves open the question about physical or logical devices. With devices like the 3390-A, which are logical even as seen without any OS, there should be somewhere discussed the idea of logical disk drives. Gah4 (talk) 00:10, 8 May 2021 (UTC)[reply]
@Gah4: Maybe a separate section in the CP/CMS article would be better? It was a unique feature of CP when it was introduced(?). Is there any material on where the idea came from? It certainly influenced many later systems including the PC-DOS partition tables. Peter Flass (talk) 01:29, 8 May 2021 (UTC)[reply]
