HBA driver for Colorado Memory Trakker 120 and Trakker 250 tape drives
Trakker 120 and Trakker 250 are two tape drives from
Colorado Memory Inc.
These drives support the QIC-40 and
QIC-80 standards respectively.
Normally, a cartridge
formatted in one drive cannot be used with the other type,
but a QIC-80 drive can read data from a tape
formatted in a QIC-40 drive.
The driver follows the
mfpd protocol to use the parallel ports.
The driver supports the following
Send a SCSI command to the drive.
Using SS_WRITE to write data
requires a SS_FLMRK (write a filemark) command
to be sent at the end
to flush any remaining buffered data to the tape.
Unsupported SCSI commands are:
Prevent or allow media removal.
Skip over filemarks only.
Return bus_name as port and drv_name
as cmtrak in the bus_type structure.
Return version number of the HBA in the structure ver_no.
The SDI_BRESET ioctl is not supported
because there is no SCSI bus.
