Folks,
I've finally got to the bottom of this. It looks like the disks may have been re-formatted with a 512 byte sector size before I got them. Either that, or the filer's maintenance mode formatted them with 512 rather than 520 bytes of its own accord.
I'd used Seagate's 'Seatools' to reset the sector size to 520 bytes, however despite telling me that it was "formatting disk with 520 byte sector size", it didn't actually do a full format.
Reformatting the disks with Seatools and 520 bytes solved the problem.
Now, next question. Anybody know how to recover a disk I accidentally labotomised by pulling it out of the shelf while its firmware was being updated?? :-|

I'm trying to resurrect an old F760 with two FC9 shelves. Both shelves have got 33GB disks in them. One shelf is recognised fine by the filer, the disks in the other are all shown as failed.
It's been a long time since I had a filer to play with, so I suspect there may be some configuration / formatting issue causing the problem rather than dead disks.
When I boot the filer I get the following:
error 19 (disk not ready for requested operation) while reading ownership on disk 1.8 (S/N 3CD1K2JW000021304AR5) error 19 (disk not ready for requested operation) on disk 1.8 (S/N 3CD1K2JW000021304AR5) while reading individual disk ownership area

No SCSI-3 Enclosure Services on channel 1 shelf 2. Check drive placement.

After booting, the filer shows:

I've moved disks from shelf 1 to shelf 2 where they appear to work okay. Disks moved from shelf 2 to shelf 1 remain dead.
I've tried booting into maintenance mode and reformatting the dead disks. This resulted in an lots of fun and games trying to recover from the 512 byte sector size that the disks were formatted with.
Has anybody got any ideas? I'm hoping it's something reasonably straightforward...
