=========================== Formatter 2.0 ============================ ====================================================================== A floppy disk formatting program, written by Olaf 'Olsen' Barthel of MXM. Copyright, © 1990 by MXM. Public domain, all rights reserved. No guarantee of any kind is made that the program(s) described in this document are 100% reliable. You use this material on your own risk. ============================== Purpose =============================== ====================================================================== The standard 'format' command surely does a brilliant job, since it gets around with any device driver and partitions of any size. But which data media is formatted most oftenly? Floppy disks (3½" format hardwired to the Amiga computer) of course. 'Formatter 2.0' was written to fit the niche for fast(er) and user friendlier floppy disk formatting programs. It also shows how to format file systems in general and how to get AmigaDOS to accept them. =============================== Usage ================================ ====================================================================== 'Formatter 2.0' can be called both from Shell and Workbench. Note that arp.library is required to run the program (Yuck!). The following command line parameters are supported: DRIVE/A........ This can be any disk drive from DF0: through DF3: as long as it's really connected. You will get an error message if the disk drive cannot be found in the current DOS mountlist. NAME/K......... The name you wish the formatted disk to receive. Any name longer than 31 characters will be truncated. FAST/S......... No secret fast formatting tricks yet, this option is similar to the 'QUICK' switch of the standard 'format' command: if enabled only the root block and the boot block of the disk will be rewritten (clearing all relevant data). If your disks have already been formatted clearing those blocks can save much time. INSTALL/S...... If you want to use the formatted disk as a bootable AmigaDOS disk, 'Formatter 2.0' will install it just as if you had used the AmigaDOS 'Install' command on it. VERIFY/S....... If enabled, each write access to disk will be verified, i.e. the disk blocks being written will be reread and compared with the source data. Needless to say, verification slows down the disk formatting process but helps to tell the good disks from the corrupt ones. AUTOSTART/S.... If enabled, any disk inserted into the specified drive will be formatted automatically. This saves some time if lots of disks have to be formatted one after the other. A small window will pop up on the Workbench screen (right under the mouse pointer if possible). The window will look like this (well, roughly, I never claimed being a graphic artist, did I?): #X#Formatter2.0======================##|## |.. .. .. .. .. .. .. .. | <- Track numbers || | | | | | | | | |----------------------------------------| | | <- Process indicator |------------+--+-------------+----------| | Auto start | | Fast format | | <- Some gadgets |------------+ +-------------+ Start | |Verify write| |Install disk | | <- Some more gadgets |--------+-+-+------+-+-------++ +-------| | DF0: | | DF1: | | DF2: | | DF3: | <- Drive selection |--------+ +--------+ +--------+ +-------| | +------------------------------| | Name: | Blank | <- Name string gadget | +------------------------------| +----------------------------------------+ Control should be intuitively (why shouldn't it, you're running Intuition anyway, aren't you?), if you've understood the command line options (to which the gadgets somehow correspond to) you should get along with the rest of the program easily. ========================= Keyboard shortcuts ========================= ====================================================================== To make life easier, each gadget in the control window can be enabled/toggled via keyboard. The keys are: A ............. Toggle 'Auto start'. F ............. Toggle 'Fast format'. V ............. Toggle 'Verify write'. I ............. Toggle 'Install disk.' 1-4 ........... Select a disk drive. Return key..... Start/Stop formatting. Escape key..... Close the window, leave the program. ====================== Formatter 2.0 vs. format ====================== ====================================================================== 'Formatter 2.0' is limited to the 3½" drives hardwired to the Amiga computer, no other filesystems will be formatted. The disks will be formatted using the old standard file system, FastFileSystem support would be easy to add (simply change the ID_DOS_DISK into ID_FFS_DISK, that's how 'format' does the trick) but isn't included yet. Formatting time is well below the time 'format' needs; formatting a disk without verify takes between 52 and 54 seconds, if verify is enabled formatting will take between 1:42 minutes and 1:44 minutes. The step delay of the drive motors is not touched, nobody knows how the different drives by various manufacturers react on different rates. ============================== Credits =============================== ====================================================================== Credits go to Mark Rinfret for the very, very basic disk formatting routines employed by his harddisk backup program. It took some time to spy out the default disk format information. The block types were picked up both from Ralph Babel's 'Amiga Guru' book and the Bantam AmigaDOS Programmers' manual. =============================== Author =============================== ====================================================================== This program was written by Olaf Barthel of MXM.

V1.0 A very limited disk formatting program. * Do only its possibilities make it an Amiga? WHERE IS THE MAGIC ???
