Re: Apple Disk Drives

I recall the feature to format a single sided disk in Finder 6.0
but I don't recall it being in Finder 7.0.1.  Who would want
to format a 400K disk anyway from a Mac Plus or better?
It wouldn't make much sense so effectively the feature was
there only for backward compatibility.  The only machines
that required a 400K was a Mac 128K, A Mac 512K and
maybe a Lisa/Mac XL.  System 7.0 required gobs of memory
and so I doubt you would have seen any older Mac using
that OS.  I used System 7.0.1 on my Mac Plus until about
1996.  That was the last release of the OS that supported
the Mac Plus.  Maybe the later releases only supported the
reading of the disk or it would only ask the Single/double
question only when a DSDD disk was inserted.  The question
would probably have been 1.44/800K on newer Macs when
you inserted a HD disk otherwise it might have asked the
800/400k question.  Since I never owned such a machine,
it is only speculation on my part.
