Q: Is is possible to use a 9.1 GB Hard drive in a NeXTstation Turbo?

[Tom C]

Hello,

I need some advice...

I have a 9.1 GB Seagate Barracuda which I would like to
install in my old NeXTstation Turbo. Unfortunately, It
has a 80-pin SCA2-connector, but I hope that this can
be overcome by using a SCSI adapter (i.e. SCA2 -> IDC50).

Can this be done?

Thanks,

Thomas Christensen

Possibly. In any case, you won't be able to use more than 4*(2048M-1K)

It's a SCSI-2 disk, so it should work without any problem both at the
logical and physical (with the right cable) level.


You'll have to write your own disktab entry to set up the partitions
though. No hope to use BuildDisk...

Sould work with a connector. Anyhow, I have one IBM 9.1GB working in a
NeXT ColorStation.

Hi henry,

Can you give me some info on writing the disktab for a 9.1 GB drive?

Thomas :-)

Hi all,
I'm a "NeXT *very* newbie"... so, sorry for my questions.
Why cannot more than 8GB be used?

Thanks in advance.

Because the UFS implementation used in NeXT software is limited to
signed 32bit to measure the size of a file system. Which amounts to
2097151 KB max.

STFW, ISTR that there are already disktab for 9GB Barracudas.

Otherwise: man disktab

This is right, but you can have 7 partitions per disk, yields approx.
14GB max.
(So having 7 disks per controller gives in turn ~100GB, a lot of noise
and heat ;-) )

YUP, I have several 9GBs take this as an example with 6 partitions, not
always 2GB in size:

And maybe a second, the already stated 18GB with 14GB usage, 7 partitions
with 2GB each (and only 1% headroom):

IBM IC35L018UWD210-0 S5:\
:ty=fixed_rw_scsi:nc#20765:nt#6:ns#284:ss#512:rm#10000:\

This gives you at least a clue how you should start to write your own
disktab entry, because those will not work with your Baracuda.

work in my mono pizza box?

To be honest, no. I had a old Quantum before, very silent, but only 700MB
in size in my Colorstation. I changed it to an also old one of IBM,
9.1GB.
In the white box I have a bunch of IBM disks, running mostly @ 10krpm.
Screaming noise everywhere. I assume in the meantime I have a freq. drop
at 1kHz...
When you had success, drop a mail or posting.

With OPENSTEP this can be augmented to 4Gbytes per partition:
4 * 7 partitions = 28Gb. Haven't tried such a device, but I did partition a 9Gb disk
into 2x4G and a 1Gb. Works without problems.

Good hint.
I did this 4GB partitioning with the18GB drive too, but the initial
question was targeted on NS3.3, as I understood.
