[comp.sys.mac] HFS on 400K disks ?

dasy@mitre-bedford.ARPA (David Shinberg) (07/09/88)

Somewhere I think I heard of a way to initialize 400K disks with
HFS.  It was probably on this group, so forgive me for asking :-)
I never was planning to use 400K disks, but at work there are some
new ones and MFS is a real pain. So how does one initialize 400K
disks to HFS format?  Please reply via email to avoid cluttering up
this group.

				Thanks in Advance

To format a 400K HFS, use a system disk with Apple's Hard Disk 20 installed. 
This is the HFS driver all of the HD20 users had to use to handle their 
drives, which also makes your floppies HFS.  It does, however, often 
corrupt and destroy your 400K's...

You can initialize a 400K disk to HFS (vice MFS)) by holding down
the option key throughout the initialization process.

Not only that, but MFS disks are the only MAC OS-formatted disks that
A/UX can recognize.
