Subject: Large Seagate drives on SS2
I have been offered the following Seagate drives. Can anybody
let me know whether I can expect to hook them up to a SS2 running
4.1.1-B without too much angst?
ST41520N Elite-1 1.3GB
ST41600N Elite-1 1.6GB
ST41650N Wren-8 1.6GB
Assuming I can come up with appropriate format.dat entries (any
contributions gratefully received) can I expect to just load up
the large disc patch and run? Any gotchas?
Sorry for the delay in summarising. Our connection to the rest
of the world went belly-up.
As I'd hoped, all that's needed is the Sun big disc patch.
We went with the ST41600N (Elite-1 1.6GB). This is apparently
sold by Sun as their SUN1.3G drive and I used those format.dat
parameters. Works like a charm.

I don't need a format.dat entry, I just feed the parameters at the
command line.

NPA is just the box manufacturer. It really contains a ST41650N
Wren-8 1.6GB.

We have the 8 ST41650 Wren-8's and 4 ST41600 Elite's attached to a
SS2 under 4.1.1 with the large disk patch and have had no problems.

The sector counts aren't usually given in the docs.

I have successfully run Wren 8's on Sun machines. You might have
some minor problem on an SS2. Early Wren VII's are known to have
a problem as system disks on SS2's. I would guess that early Wren
VIII's MIGHT have the same problem, but I've never seen that reported.

We hooked up a Wren-8 after applying the big disk
patch to SunOS 4.1.1B with no problems. This is
our format.dat entry:
disk_type = "Seagate Wren VIII ST41650N" \
: ctlr = MD21 : fmt_time = 4 \
: cache = 0x11 : trks_zone = 15 : asect = 3 \
: ncyl = 2105 : acyl = 2 : pcyl = 2107 : nhead = 15 : nsect = 87 \
: rpm = 3600 : bpt = 51330

My impression is that Sun is using ST41600N Elite-1 1.6GB as their new
1.3 GB disk (1.3 GB formatted).

You should get the software that Sun releases with its own big disk. I
believe it was available via ftp.

I can vouch for the ST41600N Elite-1 1.6GB, we bought several. They
are very zippy and easy to install. This happens to be the same
drive sold by Sun as their "SUN1.3G", so I'v been using their
format.dat entry. The Elite series is more expensive than the Wren
series, but the higher rpm and transfer rates are probably worth it.
