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: 04.01.98 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 laire@popmail.owl.de (Ralph Schmidt)
