Should scu work on a RH 5.2 multia using an ncr53c810 controller? For a new
drive that's unfortunately formatted with sector size 520, I get 'device not
configured' which I think is due to linux deleting its disk entry during
boot:
I get the following error:

I thought I saw that the way to fix this was a low-level reformat using
tools such as scsiformat from the scsiinfo package or scu. Unfortunately,
after this disk entry is deleted, neither of these tools can open /dev/sdb.
I seem to be in a catch 22.
How can I get /dev/sdb so scu or scsiformat can access it?
Thanks,

Well, it's simple with his tool. I more meant to stress that it is
possible
to change sector size of the drive, despite what you've been told.

[here you need to format].
He said that he successfully used 4K sector size for testings.
But, as it was stated in this thread too, Linux does not support
any sector size different from 512 bytes yet.
With my 73 Gig drives I was thinking to have a look around
how much hacking is necessary to get a simplest fs going -
if you'll find something please kindly inform me, I'm interested too.
