- ReOrg 3.1 Copyright (C) 1992-1993 by Holger Kruse. All rights reserved.
-
-
- This text file describes changes and enhancements to ReOrg that have
- been implemented after the manual was written and thus are not described
- in the manual.
-
-
- 1. Tooltype WINDOWXY
- --------------------
-
- In addition to the tooltypes/arguments listed in the manual
- ReOrg understands the new Tooltype "WINDOWXY". It can be used
- to specify the upper left corner of ReOrg's main window.
- Example: ReOrg WINDOWXY=10,5
- opens ReOrg's main window at the coordinates x=10
- and y=5.
- If you do not use this Tooltype ReOrg centers its main window
- within the visible portion of your screen.
-
-
- 2. Compatibility to DataFlyer(tm) harddisks
- -------------------------------------------
-
- DataFlyer(tm) harddisks use a proprietary (non-RDB) boot
- mechanism that is incompatible to previous versions of
- ReOrg. ReOrg 3.1 can optimize DataFlyer harddisks, but
- OFS<->FFS conversions are impossible.
-
-
- 3. Compatibility to MultiUserFileSystem
- ---------------------------------------
-
- The MultiUserFileSystem (muFS, (C) by Geert Uytterhoeven)
- is a variant of the standard Amiga FileSystem that adds
- the concept of user and group IDs (like Un*x) to the
- Amiga FileSystem and enforces access protection based on
- the current user ID (as set by a "Login" program).
-
- Usually the disk format used by muFS is identical to the standard
- Amiga disk format with one exception: If a partition is
- FORMATTED while muFS IS ALREADY RUNNING, the partition is
- formatted with DosType "muFS" (instead of DOS\0 - DOS\5) to
- provide some extra protection.
-
- Starting with the upcoming muFS release 1.5, muFS can also use
- the new DosTypes muF\0 - muF\5.
-
- ReOrg recognizes all DosTypes (DOS\0 - DOS\5, muFS, muF\0 - muF\5)
- and is thus compatible to all current versions of the
- MultiUserFileSystems including the upcoming release 1.5. However
- for security and compatibility reasons there are some restrictions
- as far as filesystem conversions are concerned: You can use ReOrg to
- - convert any DOS\? partition to any other DOS\? partition.
- - convert any muF\? partition to any other muF\? partition
- with one exception: If your partition is formatted as "muFS"
- and you convert it to, say, "muF\1", this partition will be
- INCOMPATIBLE to muFS versions 1.4 and below, because disk
- formats muF\0-muF\5 are not supported by muFS 1.4 and below.
- ReOrg will display a warning in this case. Please see the
- MultiUserFileSystem documentation for details.
-
- For security reasons you cannot use ReOrg to convert a partition
- between "muF\?" and "DOS\?" format. Starting with muFS
- release 1.5 the MultiUserFileSystem package will probably contain a
- tool to convert a partition back and forth between "muF\?" format
- and the corresponding "DOS\?" format.
-
- Thanks to Geert Uytterhoeven for helping me with ReOrg's muFS
- support !
-
-
- 4. New error messages
- ---------------------
-
- Some error messages are not listed in the manual:
-
- Error 46: "Sorry, OFS/FFS conversion is incompatible to your
- drive's boot mechanism !" (for DataFlyer harddisks
- only - see above)
- Error 48: "Sorry, the largest partition size supported by ReOrg
- is 16777216 blocks !" (Your partition is too large to
- optimize it - usually larger than 8 GB.)
- Error 49: "Sorry, ReOrg does not support devices with more than
- 32767 sectors !" (Probably indicates that your
- harddisk setup is incorrect - please see the
- discussion of "sectors per track" in the ReOrg manual
- chapter "Requirements".)
- Warning 507: "The resulting partition will not be recognized by
- MultiUserFileSystem release V1.4 and before ! Please
- make sure you have installed release V1.5 or higher
- before you start the filesystem conversion !"
- (see above)
-
-
- 5. Volume names in device list
- ------------------------------
-
- ReOrg now displays the names of inserted volumes together with
- the device name (if a volume is inserted in the drive),
- e.g. "DH0:System" means: Volume "System" is inserted in
- drive "DH0". If the inserted volume is unreadable,
- "????" is displayed.
-
- The device and volume list is updated each time a disk is
- inserted or removed. This works for "trackdisk.device"
- (floppy disks), but - depending on your harddisk controller -
- might not work for other removable media, like flopticals.
- Please consult your SCSI controller manual for details about
- "recognizing a diskchange".
-
-
- 6. Freeing memory under Kick3.0
- -------------------------------
-
- When ReOrg is used under Kickstart 3.0, it sets the new
- MEMF_NO_EXPUNGE flag for most memory allocations. This means
- that unused libraries, devices etc. are NOT removed from
- memory when ReOrg starts the optimization.
-
- This is useful to prevent important libraries, catalogs etc.
- from "disappearing" and thus helps to prevent low-memory
- situations during the optimization.
-
- However there are situations when you need to have the
- maximum amount of memory available for ReOrg, eg. if you
- used SAS/C V6.x before and have all those scxxx.library
- and xxx.gst files still in memory. In this case enter
- the command "avail flush" in a Shell window before you
- start ReOrg. This removes all unused libraries from
- your system and gives ReOrg more memory for its cache.
-
-
- 7. Some additional hints
- ------------------------
-
- - You should ALWAYS select one of the "predefined settings"
- first (see the manual chapter "menus" section
- "menu predefined settings") and THEN make any adjustments
- you need (like selecting a different device). This ensures
- that you do not mistakenly have an option set to a wrong value.
-
- - If you want to have the fastes possible directory access, here
- are some hints:
-
- - Set the gadget "small file limit" to a very small
- value (0 or 1).
- - If you use Workbench and need fast icon display, switch
- Workbench mode on. Otherwise switch it off.
- - Set the "Optimize for (Kick1.2/1.3 / Kick2.0/3.0)"
- gadget correctly depending on your Kickstart version.
- - If you use Kickstart 3.x, use "Directory Caching".
- If your disk is formatted without "Directory Caching",
- you can use ReOrg to convert it. Set "Change filesystem"
- to "to DCFS mode".
- Warning: - DCFS disks can ONLY be read by Kickstart 3.x,
- NOT by Kickstart 2.x.
- - The V39 FileSystem (Kick3.0) is not as reliable in
- DCFS mode as in standard mode. This is supposed
- to improve with the next Kickstart version (3.1 ?).
- - If your disk is formatted using DCFS you should not use
- filenotes (comments) unless really necessary. Under DCFS
- filenotes need additional space on your harddisk and slow
- down directory accesses.
-
- - As already mentioned in the manual:
- - Do not play around with the "read drive geometry" gadget
- unless you know exactly what you are doing !
- - Set "Format" and "Verify" to "Off" for harddisks !
-
-
- And: PLEASE read the manual before using ReOrg !
