da0: invalid sector size 520
Thomas Stromberg
da0: <SEAGATE ST15150N 3514> Fixed Direct Access SCSI-2 device
da0: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled
da0: 4087MB (8242659 520 byte sectors: 255H 63S/T 513C)
notice the 520 byte sectors? This occurs whenever I try to do any
operations (sysinstall, dd, disklabel) with da0:
da0: invalid sector size 520
The machine is 5.0-CURRENT as of Wednesday, but I dont think that will
matter much. Is there something I'm missing? Please CC any replies to
me, I'm not on this particular list.

Guessing:
Could be a disk from a machine that uses hardware RAID or extra checksumming
in the 8 bytes beyond 512 bytes/sector. You can try to reformat the drive
while first selecting 512 bytes/sector.

Not sure where this disk came from, got it from Ebay. The problem I have
is I'm getting this error while trying to reformat it.. from sysinstall,
disklabel, newfs, and dd.. Any advice on how to re-format this disk that
I'm missing? I'm not very experieced with SCSI stuff.
BTW, I'm not on the SCSI mailing list, so any replies should be CC'd to
me

This is a drive that was in a raid unit. Reformat to to 512 byte
sectors. There's some camcontrol magic for doing this, but, frankly, I just
use Solaris.

disklabel, newsfs and dd don't format the disk though. You will need to
do a low-level SCSI re-format in order to change the sector size to 512
bytes.
If you read the manpage for "camcontrol", the section on the format
option specifically mentions changing the sector size. If looks like you
should change the sector size in the modepage, then issue the format
command.

See the man page for 'camcontrol'. You need to give it a low-level SCSI
format. Things like 'dd' etc don't do that for you..

Try this:
========================================================================
Yup, there's some other way to change it. Set the current values,
then immediately issue a format command:
# camcontrol cmd da1 -v -c "15 10 0 0 v:i1 0" 12 -o 12 "0 0 0 8 0 0:i3 0 v:i3" 512
# camcontrol cmd -n da -u 1 -v -t 7200 -c "4 0 0 0 0 0"
# camcontrol modepage da1 -m 3
Tracks per Zone: 19
Alternate Sectors per Zone: 12
Alternate Tracks per Zone: 0
Alternate Tracks per Logical Unit: 38
Sectors per Track: 84
Data Bytes per Physical Sector: 512
Interleave: 1
Track Skew Factor: 13
Cylinder Skew Factor: 22
SSEC: 0
HSEC: 1
RMB: 0
SURF: 0
