- Short: FastFileSystem with TD64 (>4GB) support
- Author: laire@popmail.owl.de (Ralph Schmidt)
- Uploader: olli@elaborate-bytes.com (Oliver Kastl)
- Version: 44.5
- Type: disk/misc
- Kurz: FastFileSystem mit TD64 (>4GB) Unterstützung
- Requires: OS 2.04, OS 3.0 or better recommended.
- Date: 01.01.98
-
- The patch files included in this archive serve to update
- versions 40.1 and 40.4 of Commodore's FastFileSystem and
- version 38.2 of Commodore's CLI command "Info" to handle
- partitions larger than 4 GB. The new filesystem provides
- support for the TD64 standard, which has been defined by
- an independent group of third-party Amiga developers. The
- trackdisk64 specification itself is available from Aminet
- sites (dev/misc/trackdisk64.lha). It is supported by:
-
- Dan Babcock
- Ralph Babel
- Jamie Cooper
- Randell Jesup
- Oliver Kastl
- Bernhard Möllemann
- Matthias Scheler
- Ralph Schmidt
- Michael B. Smith
-
- Features of the new filesystem:
-
- - supports TD64 API for TD64-aware devices.
-
- - supports HD_SCSICMD for non-TD64-aware devices, so almost
- everyone with a working Direct SCSI interface can use hard
- disks larger than 4 GB without any device update (which
- may be impossible for older hardware).
- ATTENTION:
- Don't create partitions greater than 2GB(Dos Limitation)
-
- - supports TD_GETGEOMETRY (to update a removable medium's
- geometry automatically). The following devices are known
- to implement TD_GETGEOMETRY:
-
- 1230scsi.device(Phase5's Blizzard I-IV,Blizzard 1260)
- 2060scsi.device(Phase5's Blizzard 2060)
- ALF.device(BSC's Alf Controller)
- carddisk.device
- cybscsi.device(CyberSCSI I-II)
- dracoscsi.device(Macrosystem's Draco)
- oktagon.device(BSC's Oktagon)
- omniscsi.device(Ralph Babel's GuruRom)
- trackdisk.device
- z3scsi.device(Phase5's Fastlane Z3)
-
- The following devices are known to be potentially incompatible
- and are mapped out for the DriveGeometry functionality.
- The list currently includes:
-
- scsi.device (All CBM SCSI Devices)
- HardFrame.device (Microbotics HardFrame)
- scsidev.device (GVP Series I)
- hddisk.device (CBM A2090)
- statram.device (Ram Disk)
- ramdrive.device (Ram Disk)
-
- - MountList/DOSDrivers/RDB entries for cyclinder, surfaces,
- and sectors are no longer limited to 16-bit quantities.
-
- - automatically disables TD64 for drivers that are known to
- be potentially incompatible. The list currently includes:
-
- HardFrame.device (Microbotics HardFrame)
- statram.device (Ram Disk)
- ramdrive.device (Ram Disk)
-
- - automatically disables SCSIDirect for drivers that are known
- to be potentially incompatible. The list currently includes:
-
- scsidev.device (GVP Series I)
- hddisk.device (CBM A2090)
- statram.device (Ram Disk)
- ramdrive.device (Ram Disk)
-
- If you create a partition >4GB border the FFS can't handle
- this case for these devices.
-
-
- - an RDB extension to manually disable certain FFS tests for
- broken drivers the TD64 developers were not aware of:
-
- de_Control, bit 0: set to 1 to skip TD_GETGEOMETRY test
- de_Control, bit 1: set to 1 to skip TD64 test
- de_Control, bit 2: set to 1 to mark a device as broken scsidirekt
-
- - a TD64-/HD_SCSICMD-aware Format command is in the works.

- INSTALLATION:
-
- If your l:fastfilesystem is 40.4 then use this shell line
-
- spatch -ol:fastfilesystem_44_1 -pfastfilesystem_40_4.patch l:fastfilesystem
-
- If your l:fastfilesystem is 40.1 then use this shell line
-
- spatch -ol:fastfilesystem_44_1 -pfastfilesystem_40_1.patch l:fastfilesystem
-
-
- RELEASENOTES:
-
- o 44.5
- - Added a -1 io_error check for the TD64 test.
- scsi.device doesn`t return IOERR_NOCMD
-
- o 44.4
- - Sorry..the 44.3 init fix wasn`t perfect and the BUMP didn`t work
-
- o 44.3
- - Fixed a de_Control problem which could lead to failed inits
-
- o 44.2
- - Fixed a problem with detecting >4GB access.
-
- o 44.1
- - Initial Release
-
-
-
- BUGREPORTS:
-
- o Bugreports about a crashing ffs are WORTHLESS if you don't provide
- segtracker/tnt(both tools are on Aminet and a MUST HAVE) informations.
-
-
- ATTENTION:
-
- Probably not all devices which are incompatible with this FFS patch
- are listed in the disable tables. Therefore we need the feedback for
- incompatible and ancient devices.
-
- PROBLEMS
-
- o Don`t use REORG on a partition after the 4GB border
- o Don`t use DiskSalv on a partition after the 4GB border
- o Don`t use AmibackTools on a partition after the 4GB border
- o Don`t use QuarterbackTools on a partition after the 4GB border
- o Don`t use DynamiCache on a partition after the 4GB border
