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 !
