I also get the following message from dmesg:

(sa0:ahc0:0:6:0): Invalid request.  Fixed block device requests must be
a multiple of 1 bytes

| Hi All,

|     I am currently trying to get a DSS-4 type drive working on a 5.2.1
| RELEASE system but am haveing no joy at all. From dmesg at boot the
| device if found as
|
| sa0 at ahc0 bus 0 target 6 lun 0
| sa0: <ARCHIVE Python 06408-XXX 8130> Removable Sequential Access SCSI-3
| device
| sa0: 80.000MB/s transfers (40.000MHz, offset 32, 16bit)
|
|
|     'mt status' gives the following (first 2 lines)
|
| Mode      Density              Blocksize      bpi      Compression
| Current:  0x26:DDS-4           1024 bytes     97000    DCLZ
|
|     I have also tried setting blocksize to variable without any
success (mt
| blocksize 0).
|
|     Now when i try to use dump or tar the system will just sit there
untill
| i get a kernel: <<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>>
| message which then locks out the tape drive untill.
|
| For an example the command 'tar -cf /dev/sa0 /root/*-supfile' gave the
| following dump...
|
| For reference ls -l /root/*-supfile returns...
|
| -r--r--r--  1 root  wheel  2761 Apr  9 17:23 /root/doc-supfile
| -r--r--r--  1 root  wheel  3831 Apr  9 17:22 /root/ports-supfile
