Hard Drive Parameters

GEAR uses the following values to raw read from or write to a hard disk using the PHYSTRK command. These values are required.


DiskInterface Identifies the SCSI driver to use for interfacing with raw hard disk devices. The default value is 2 (Stardard SCSI driver).


SCSIPath2 Identifies a template for the device-special file used for accessing a hard disk device, when the standard platform SCSI-driver is used. This value must be correct, otherwise the software cannot locate the device. The default value depends on your Unix system.


TargetID Identifies the target ID of the hard disk device to use. On some Unix platforms the ID is equivalent to the SCSI ID of the device, but on some Unix platforms the ID might only be a logical number assigned by the kernel that has no relation with the actual SCSI ID. GEAR combines the TargetID with the SCSIPath template to construct the name of device special file to open for the device.


SCSIBusID Identifies the SCSI Bus ID of the hard disk device to use. Valid values are 0 to 7. Not all Unix systems actually use the bus ID. On some Unix platforms GEAR combines both the SCSIBusID and the TargetID with the SCSIPath template to construct the name of device special file to open for the device.
