,/* IBM format */
Despite its name, the IBM format is not usable on PC as it uses the CP/M filesystem. PC floppies use the FAT12 filesystem instead.
Another issue is that only the earliest PCs used 8 sectors per track (MS-DOS 1.0 and 1.1). They switched to 9 sectors per track with MS-DOS 2.0in 1983. [https://minuszerodegrees.net/5150/early/5150_early.htm Source]
Also, [[CP/M|CP/M]] 2.2 supports the IBM format but CP/M Plus does not.
