Tooltypes

A list of Tootypes recognized by RDB-Salv follows. Values appropriate to the computer should be set before starting RDB-Salv.

DEVICE=<default-devicename>

The device driver normally used, e.g. `scsi.device'. This value can be easily changed later from within the GUI. Please refer to your hard disk system manual to determine a suitable value.

UNIT=<default-unit>

Device unit normally used, e.g. `0' for Unit 0. This value can be easily changed later from within the GUI. Please refer to your hard disk system manual to determine a suitable value.

BACKUPFILENAME=<default-backupfilename>

Default filename for the backup copy, e.g. `DF0:RDB-Backup'. This value can be easily changed later from within the GUI.

BUFMEMTYPE=<bufmemtype>

Memory type from which to use for device access. This value only makes sense when NOGETGEOMETRY has been set or if the device driver does not support TD_GETGEOMETRY. TD_GETGEOMETRY if available defines the type of memory and this will always be used. Please refer to your hard disk system manual to determine a suitable value. If your manual doesn't help, then it's best to use 0x00000001 which corresponds to MEMF_PUBLIC.

MAXTRANSFER

Smallest MaxTransfer value for all disks. This value is used by RDB-Salv and passed on to potential file systems. Please refer to your hard disk system manual to determine a suitable value. One is usually safe to specify 0x0000FE00 -- although this has an unfortunate side-effect of significantly reduced transfer rates over higher values. Values which are too high can lead to data transfer problems. If in doubt, try it out. If you are unsure, then sacrifice speed for reliability and specify the 0x0000FE00 value.

MASK

Desired value for Mask. The value will be passed on to potential file systems. Please refer to your hard disk system manual to determine a suitable value. If that doesn't help, try it with 0xFFFFFFFE. That value is now used by most systems. RDB-Salv only does data transfers to memory which has been obtained from AllocMem(), and doesn't validate that this agrees with MASK.

NOGETGEOMETRY

Prevent despatch of TD_GETGEOMETRY. You must set this option if your device driver crashes when it gets a TD_GETGEOMETRY. If your device driver doesn't support TD_GETGEOMETRY, you should set this option to avoid unnerving Alerts. Consider upgrading your device driver anyway. The following symptoms indicate that your device driver has trouble with TD_GETGEOMETRY:

• You get a warning requester when you first press Start, telling you that TD_GETGEOMETRY isn't working.
• Your machine crashes after your first click on Start.

NONEWSTYLE

Don't use New-Style commands. You must set this if your device driver crashes when it gets a NSCMD_DEVICEQUERY. Do not set this option if your device driver simply doesn't implement this command (applies to almost all drivers as it is very new). You can tell if your device driver has problems with NSCMD_DEVICEQUERY because your computer will crash when you first click on Start.

NOSCSICMD

Prevent despatch of HDSCSICMD. If your device driver crashes when it gets a HDSCSICMD, then you must set this option. Should your device driver not support HDSCSICMD, you can set this option to avoid annoying alerts. You should consider a device driver update anyway. The following symptoms indicate that your device driver has trouble with HDSCSICMD:

• You get a requester telling you that HDSCSICMD isn't working; probably preceded by another that says that TD_GETGEOMETRY isn't working either.
• Your computer crashes after clicking on Start for the first time, possibly preceded by a warning about TD_GETGEOMETRY not working.

SCSIREADWRITE

Use SCSI-Direct commands (HDSCSICMD) to read and write hard disk blocks. This option is not allowed if NOSCSICMD is set. This will become significant in future -- when hard disks larger than 4 GB are the rule, rather than the exception -- as it allows addressing of SCSI disks larger than 4 GB.

BADDEVICE1

This option should not normally be set. It is only to be set if the return code from attempting to read non-existent blocks is inconsistent. This is a hack to allow for bad device drivers.

NORECOVER

Switch off Find lost blocks when NORECOVER is set. This value can be easily changed later from within the GUI. As an alternative, a Tooltype can by the way be set to RECOVER=TRUE|YES|1 to explicitly switch on Find lost blocks.

READDEVLIST

The Read function will default to Read from DeviceList when this is set -- Read from Media otherwise. This value can be easily changed later from within the GUI.

OPTIMIZE

Activate Optimize for the Backup function. Storage of the management blocks will be optimized to reduce space requirements. Unused blocks which may still contain lost data will not be backed up. This value can be easily changed later from within the GUI.

DEBUG

Debug mode -- should not normally be switched on.

If you're an expert and prefer to use the shell, then these Tooltypes can be specified as parameters to the program -- unless otherwise specified.
