@sj_zero @retrocomputing Did anyone figure out if scandisk was actually licensed from someone else? I know that lots of the other MS utils were - defrag, undelete etc

@DavidGA @retrocomputing Exactly, here’s the canonical The Old New Thing post on the topic. https://devblogs.microsoft.com/oldnewthing/20071224-00/?p=24063
tldr:
“MS-DOS served two purposes in Windows 95: It served as the boot loader. It acted as the 16-bit legacy device driver layer.”
“Among other things those drivers did was “suck the brains out of MS-DOS,” transfer all that state to the 32-bit file system manager, and then shut off MS-DOS.”
