They are not generically accessable to * the user as they do not appear on any DOS drive. The blocks * are tagged with a unique identifier, checksummed, and linked * together. The root of these blocks is the RigidDiskBlock. * * The RigidDiskBlock must exist on the disk within the first * RDB_LOCATION_LIMIT blocks. This inhibits the use of the zero * cylinder in an AmigaDOS partition: although it is strictly * possible to store the RigidDiskBlock data in the reserved * area of a partition, this practice is discouraged since the * reserved blocks of a partition are overwritten by "Format", * "Install", "DiskCopy", etc. The recommended disk layout, * then, is to use the first cylinder(s) to store all the drive * data specified by these blocks: i.e. partition descriptions, * file system load images, drive bad block maps, spare blocks, * etc. * * Though only 512 byte blocks are currently supported by the * file system, this proposal tries to be forward-looking by * making the block size explicit, and by using only the first * 256 bytes for all blocks but the LoadSeg data. * *------------------------------------------------------------------*/ /* * NOTE * optional block addresses below contain $ffffffff to indicate * a NULL address, as zero is a valid address */ STRUCT RigidDiskBlock LONGINT rdb_ID /* 4 character identifier */ LONGINT rdb_SummedLongs /* size of this checksummed structure */ LONGINT rdb_ChkSum /* block checksum (longword sum to zero) */ LONGINT rdb_HostID /* SCSI Target ID of host */ LONGINT rdb_BlockBytes /* size of disk blocks */ LONGINT rdb_Flags /* see below for defines */ /* block list heads */ LONGINT rdb_BadBlockList /* optional bad block list */ LONGINT rdb_PartitionList /* optional first partition block */ LONGINT rdb_FileSysHeaderList /* optional file system header block */ LONGINT rdb_DriveInit /* optional drive-specific init code */ /* DriveInit(lun, rdb, ior): "C" stk & d0/a0/a1 */ STRING rdb_Reserved1 SIZE 24 /* 6*SIZEOF(LONGINT) */ /* set TO $ffffffff */ /* physical drive characteristics */ LONGINT rdb_Cylinders /* number of drive cylinders */ LONGINT rdb_Sectors /* sectors per track */ LONGINT rdb_Heads /* number of drive heads */ LONGINT rdb_Interleave /* interleave */ LONGINT rdb_Park /* landing zone cylinder */ STRING rdb_Reserved2 SIZE 12 /* 3*SIZEOF(LONGINT) */ LONGINT rdb_WritePreComp /* starting cylinder: write precompensation */ LONGINT rdb_ReducedWrite /* starting cylinder: reduced write current */ LONGINT rdb_StepRate /* drive step rate */ STRING rdb_Reserved3 SIZE 20 /* 5*SIZEOF(LONGINT) */ /* logical drive characteristics */ LONGINT rdb_RDBBlocksLo /* low block of range reserved for hardblocks */ LONGINT rdb_RDBBlocksHi /* high block of range for these hardblocks */ LONGINT rdb_LoCylinder /* low cylinder of partitionable disk area */ LONGINT rdb_HiCylinder /* high cylinder of partitionable data area */ LONGINT rdb_CylBlocks /* number of blocks available per cylinder */ LONGINT rdb_AutoParkSeconds /* zero for no auto park */ LONGINT rdb_HighRDSKBlock /* highest block used by RDSK */ /* (not including replacement bad blocks) */ LONGINT rdb_Reserved4 /* drive identification */ STRING rdb_DiskVendor SIZE 8 STRING rdb_DiskProduct SIZE 16 STRING rdb_DiskRevision SIZE 4 STRING rdb_ControllerVendor SIZE 8 STRING rdb_ControllerProduct SIZE 16 STRING rdb_ControllerRevision SIZE 4 STRING rdb_Reserved5 SIZE 40 /* 10*SIZEOF(LONGINT) */ END STRUCT #define IDNAME_RIGIDDISK &H5244534B /* 'RDSK' */ #define RDB_LOCATION_LIMIT 16 #define RDBFB_LAST 0 /* no disks exist to be configured after */ #define RDBFF_LAST &H01& /* this one ON this controller */ #define RDBFB_LASTLUN 1 /* no LUNs exist to be configured greater */ #define RDBFF_LASTLUN &H02& /* than this one at this SCSI Target ID */ #define RDBFB_LASTTID 2 /* no Target IDs exist to be configured */ #define RDBFF_LASTTID &H04& /* greater than this one ON this SCSI bus */ #define RDBFB_NORESELECT 3 /* don't bother trying to perform reselection */ #define RDBFF_NORESELECT &H08& /* when talking TO this drive */ #define RDBFB_DISKID 4 /* rdb_Disk... identification valid */ #define RDBFF_DISKID &H10& #define RDBFB_CTRLRID 5 /* rdb_Controller... identification valid */ #define RDBFF_CTRLRID &H20& /* added 7/20/89 by commodore: */ #define RDBFB_SYNCH 6 /* drive supports scsi synchronous mode */ #define RDBFF_SYNCH &H40& /* CAN BE DANGEROUS TO USE IF IT DOESN'T!
