- TestGeometry documentation
- **************************
-
- This document describes TestGeometry, a test and demonstration program
- for the TD_GETGEOMETRY and TD_PROTSTATUS commands that may be implemented
- in trackdisk.device-compatible Exec devices.
-
-
- Purpose
- *******
-
- There are several programs that need or can use TD_GETGEOMETRY, most of
- them are low-level disk utilities. Often there is no documentation which
- commands a device driver understands and not all programs using
- TD_GETGEOMETRY give meaningful error messages, so you can use
- TestGeometry first to check if your device does support it or not.
-
- You should get correct information about the device geometry if
- TD_GETGEOMETRY is supported, or "error -3 (command not supported by
- device) reading drive geometry" if not.
-
- Another possible use for TestGeometry (if the appropriate driver does
- support TD_GETGEOMETRY) is to obtain the geometry of a certain disk,
- for example for preparing it or for writing DEVS:DOSDrivers-files.
- If you have a device driver with a good TD_GETGEOMETRY implementation,
- like the omniscsi.device ("Guru-ROM"), you can get better values with
- this program than from HDToolBox.
-
-
- Usage
- *****
-
- TestGeometry is a Shell program with the following template:
-
- DEVICE/A,UNIT/N/A
-
- DEVICE is the name of the trackdisk.device-compatible Exec device
- you wish to use.
-
- UNIT is the unit number of the given device you with to use.
-
-
- Examples
- ********
-
- TestGeometry scsi.device 3 (unit 3 of Commodore's scsi.device)
- TestGeometry trackdisk.device 1 (the Amiga formatted disk in DF1:)
- TestGeometry mfm.device 0 (the CrossDOS-disk in PC0:)
-
-
- Tested device drivers
- *********************
-
- The following drivers support TD_GETGEOMETRY:
- omniscsi.device (Guru-ROM V6)
- mfm.device 40.9 (21.05.93) (OS 3.1 CrossDOS disk driver)
- trackdisk.device 40.1 (12.03.93) (OS 3.1 floppy disk driver)
- scsi.device 40.20 (18.02.94) (A3000 Kickstart 40.70)
-
- The following drivers do NOT support TD_GETGEOMETRY:
- gvpscsi.device (GVP SCSI-driver)
- ramdrive.device 39.35 (21.05.92) (OS 3.1 recoverable RAM disk)
- scsi.device 40.12 (21.12.93) (A3000 Kickstart 40.68)
