I got a bunch of 72G IBM UltraStars that were taken from some
kind of IBM storage server. The Linux kernel however doesn't
like them, complaining about a non-512 byte sector size:
scsi 0:0:1:0: Direct-Access IBM IC35L073UCDY10-0 S27N PQ: 0 ANSI: 3
scsi target0:0:1: tagged command queuing enabled, command queue depth 16.
scsi target0:0:1: Beginning Domain Validation
scsi target0:0:1: FAST-20 WIDE SCSI 40.0 MB/s ST (50 ns, offset 8)
scsi target0:0:1: Domain Validation skipping write tests
scsi target0:0:1: Ending Domain Validation
sd 0:0:1:0: [sdb] Unsupported sector size 524.
(that's from the 2.6.35 kernel's SYM53C8XX_2)
According to the datasheets these drives have soft-configurable
sector sizes from 512 up to 528 bytes, but they don't say how
that configuration is done.
Any ideas on how to reconfigure these drives for 512-byte sectors?

Low level format?
Greetings,

How would I do that in Linux? I assume it requires some
SCSI-specific tool, or perhaps even a vendor-specific one.

I've only done this in BSD before, but it looks like something like
http://sg.danny.cz/sg/sg3_utils.html could be useful.
I don't know about the software configurability here, but normally you
would first need to update the firmware to something that understands
512b sectors, then low level format.
Greetings,
Michael.

sg_format --format --size=512 /dev/<disk>

I tested that on one of the disks and solved the detection problem.
Thanks.
