1841.0. "Important FFS questions." by RAVEN1::EVERHART () Tue Nov 01 1988 16:52

    	I have a couple questions about FFS and floppies.  I understand
    that you need CHANGEDISK. (which makes it unacceptable for such
    use).  If you neglect to use CHANGEDISK, exactly what happens? 
    Is there a buffer that gets written onto the next disk?  If so,
    does this buffer NEED to be written on the previous disk, or is
    it just left over from the last write?  What I am getting at here
    is a possible program that will check for a disk eject.  (a la MUNCHO)
    I need to know whether or not I have to make the file system write
    the buffer to the old disk, or just flush it out.  Can someone help?

1841.1RDCV01::RANDREWSI have a cunning planTue Nov 01 1988 17:139
    Chris,
    
    Just the other day I saw a program on comp.binaries.amiga that would
    allegedly do the thing you are asking.  It would detect diskchanges
    and do the DISKCHANGE command for you.  Check the Amiga_usenet
    conference for the file.  You'll probably have to unshar, and uudecode
    it.  I haven't really checked it out myself, as I haven't gotten
    1.3 yet.

1841.2already done...ROMULN::MYEEBoycott Styrofoam cups, save the ozone.Tue Nov 01 1988 17:1511
    
    	There's aready a program that lets you use FFS on you floppys.
     It's called AutoChange and you can get it from:
    
    	Romuln""::dub3:[public.amiga]ffsfloppy.zoo (really autochange)
    
    I haven't tried this program to see if using FFS on floppies are
    worth it.  So, tell me how it works out...

1841.3...LEDS::ACCIARDIDukakis should pluck his eyebrowsTue Nov 01 1988 17:1521
    
    Ah, I believe I saw reference to an AUTOCHANGEDISK program that
    obviated the need to tell the system that a MOUNTed floppy had been
    changed.  (Floppies need a mountlist entry under FFS).
    
    I'll check PLINK.  If this does exist, it may make FFS floppies
    feasable.  Unless someone can think of a good reason why this may
    be dangerous.

    PS:  Anyone who hasn't tried the FASTDISK program in my directory,
         should.  It rewrites the floppies in a totally compatible way
         such that .info files and directory listings are located on
         nearby tracks.  Of course, as the disk fragments, the scheme
         breaks down.  FASTDISK really works.  Icons pop up almost as
         fast as a non-FFS hard drive.

    Wow, talk about notes crossing in the mail!  Three virtually identicle
    replies crossed!  That may be a record.

1841.5Thanks!RAVEN1::EVERHARTWed Nov 02 1988 15:426
    	Thanks for the answers guys.  Y'all probably just saved me about
    a months worth of work, as it would take me that long to figure
    out what the heck I was doing.
