| 1917.1 | swap drives? | PERFOM::HENNING | | Wed Apr 09 1997 00:12 | 4 |
| when you say you tried two different cdroms, do you mean two different
drives or two different cd's?
I'd try a different drive....

| RE .0 - AlphaStation 255 CD-ROM problem: Block size is NOT 512 bytes
for device dkaX00...
Has this drive ever worked?
There's probably a jumper or a switch on the CD-ROM drive that selects
either 512- or 2048-Byte operation. The CD disks are all the same
(2048-Byte sectors), the drive just fakes the 512-Byte mode to make
some drivers happy.
If it's not obvious what to twiddle once you get the drive out for
inspection, get back here with the manufacturer and model number.

| 1917.3 | >>>SHOW DEVICE | STAR::jacobi.zko.dec.com::jacobi | Paul A. Jacobi - OpenVMS Systems Group | Wed Apr 09 1997 14:10 | 13 |
| >>>show device
If the device is "RRD45" then it is in 512 mode, If it say "toshiba" or
"sony" then it is probably in 2K mode. If the system was ever used with
NT, then the jumper is probably in the 2K mode.
Doesn't the SRM console issue a SET MODE SCSI command to force the device
in 512byte mode? Perhaps this command is failing because the device did
not accept the command.

| 1917.4 | Block size not 512 bytes for dka400 | CSC32::S_GRIMMER | | Wed Apr 09 1997 19:41 | 12 |
| For clarification I used multiple CDROM drives and multiple cd's.
The drive I have is a Toshiba XM5401B/D1. It has a pcmode/digital work
station switch. When in pc mode the computer continously reboots, when
in digital workstation mode it boots to srm >>> but I still get the
'block size is NOT 512 bytes for dkaX00...'. The drive came from the
factory with the jumper set to digital workstation mode.
I can't seem to find any set mode scsi command there is a scsi_fast
switch I have tried that switch set to 0 and 1 no effect on problem.
The device show up as a rrd45.

Just for yucks. Make sure you do not have a improper SCSI bus
configuration - too long, or bad termination. Unplug the external
cable, and try it. Maybe you are getting flakey communications with
the CD.

| 1917.6 | scsi setup, block size not 512 bytes | CSC32::S_GRIMMER | | Fri Apr 11 1997 00:14 | 6 |
| Current setup of 255 scsi bus.
No externel connections. One internal rz28d, One toshiba cdrom, one
terminator. I have tried it with only the cdrom on the scsi bus.
I have no way to test the scsi or do i?
I tried another scsi cable and that didn't work either.

| Block size is not 512 bytes for device dkxxx
Problem turned out to be conflict with video card.
