- Documentation for M-Disk 2.0 for Atari ST
- =========================================
-
- M-Disk provides
- - a sizable removable multi-function ramdisk
- - a floppy disk copy program
- - a harddisk backup program
- - a harddisk cache program (optional)
- all in one program.
-
- If you know Moshe Braner's Flexcopy, then you may view M-Disk as a RamDisk
- with integrated Flexcopy and Harddisk-Cache. The Flexcopy part is now even
- more flexible: You may read/write disks with a different numbers of FAT
- sectors, such as OS/2-compatible Disks.
-
- Included files:
- ===============
-
- - MDISK.ACC (the program)
- - MDISKSET.TOS (setup for M-Disk, see below)
- - MDISK20A.DOC (this document)
-
- Installing the RamDisk:
- =======================
-
- Move MDISK.ACC to the root directory of your boot disk, then reboot.
- Now there's a Desk Accessory entry "M-Disk 2.0a", that lets you select
- a size for your ramdisk. Enter a size, then click "Install". Now M-Disk
- is active. Install a disk Icon for M-Disk, so you can click on it. M-Disk
- is always on drive M.
-
- Copying from/to the M-Disk:
- ===========================
-
- Since Floppy Disks are soooooo slow, there is an option to load/save a whole
- Floppy Disk at once. This will make a plain copy of all files an directories,
- destroying the whole prior contents. The serial number of the Disk, however
- is not changed. The load/save option actually is the clou of the program.
- It will save you lots of time.
-
- Use as Disk Copier:
- ===================
-
- First load the source disk into M-Disk, then save onto the target disk.
- Most common floppy formats are supported. The formats of the source and
- target disks need not be the same, so you can quick and easy copy
- a single sided disk to a double sided or IBM PS/2 or 800 KB Disk. You may
- even copy a double sided to a single sided disk, if the target disk has
- enough space.
-
- Use as Backup Program:
- ======================
-
- Backup:
- You probably won't Backup the whole Hard disk at once, so select the
- part, you want to save, then install an M-Disk, that is big enough to
- hold your data. If you make it small enough to fit on your floppy disk,
- you can copy files from the Harddisk to M-Disk until M-Disk is full.
- Now save the data with the "save onto disk" option onto a floppy.
- HINT: Use the cache.
- Restore:
- Load your Backup Disk into M-Disk (with "load disk"). Then copy the files
- from M-Disk to your Hard Disk. This is *much* faster, than copying
- directly from floppy to harddisk.
- Incremental Backup:
- Load your (old) backup floppy into M-Disk. Delete some files, copy new
- versions from the harddisk to M-Disk. When your finished, save the result
- again onto your floppy.
-
- Using the Harddisk Cache:
- =========================
-
- When you boot with the M-Disk accessory, it will install a small and simple
- (LRU) cache for Drives C - F. The cacheing takes place in a 32k buffer, that
- will not be available, if the cache is totally locked (see below).
-
- Whenever you change the cached drives, the cache is completely reinitialized.
- So if you for some reason want to kill the cache contents, you may simply
- change the drives list.
-
- STOP !
- >>>>>>>>> Be sure to cache only fixed media. The cache will ignore
- >>>>>>>>> media changes on the cached drives.
- STOP !
-
- Only directories (root+folders) and small files are cached by M-Disk.
- The Cache is big enough to catch all the directories that you need for
- your work on a special application. It may be not big enough to cache
- all the directories on a partition.
-
- Customizing M-Disk
- ==================
-
- You may want to set up your own startup-defaults for M-Disk. This can be
- done with MDISKSET.TOS. Put MDISKSET.TOS into one directory with MDISK.ACC,
- the click on it. It will ask you some questions about the defaults you want
- to use.
-
- You may also totally deactivate the cache here, by answering NO to the
- "provide cache" question. In this case, no space is allocated for cache.
-
- An alternative may be, to anwer YES, but don't install any drives to cache.
- In this case, the buffer is allocated at boot time and you may install
- cache for your drives later.
-
- WARNING:
- ========
-
- TurboDos has Problems with M-Disk since it seems to ignore all
- media change signals from drives > 'B'. Don't use M-Disk with
- TurboDos.
-
- Use FATSPEED with M-Disk's cache and you will get TurboDos speed
- without TurboDos.
