[rescue] SCSI2SD formatting

[CLIFFORD HAIGHT]

Agreed the SCSI2SD is expensive but is still significantly less expensive then
the SCSI to CF, IDE and SATA adapters.
I tried purchasing two 50pin SCSI drives, but had issue with both.
A WDE4360 which would have been great and for sure would have meet my needs
but pin 50 broke.   I soldered another new pin but it didnbt work again
afterwards.
Then I bought a refurbish maxtor drive, sadly it was DoA.

After that I got a Conner CFP1080SN which was picked right away as a SUN1.02.
This drive is working just fine but on it own is still a little small for even
a full system with SunOS 4.

Sca80 and 68 pin drives are plentiful and cheap but in the SS10 the space
limitationbs make it hard to use adapters. Now I didn't try looking a
notebook SCSI drives but I think these come at even higher premium that 50pin
SCSI dRives.

I am not sure if the SCSI2SD is much faster than the conner drive.   I think
the. Wde4360 might have been faster.

True as it is, the SCSI2SD has advantages of its own.

You can get a lot more data than in a vintage hard drive (not many narrow
drives larger than 2GB, everybody in the workstation market switched to
wide SCSI).

It's lighter and less noisy :-)

They're very easy to backup - just put the SD card in your regular
desktop/laptop, and a single 'dd' later you have a full-drive backup of your
workstation. Not many amateur collectors still have the ability to connect
parallel SCSI devices to their main system, I think (I know I don't - SAS
has superseded it...)

And a single card can be split in many "virtual" drives - so with a single
8 GB
card, you can e.g. have 4 2GB "virtual" drives. All of them can have a
bootable
partition inside the first GB. So you can have SunOS, Solaris, NetBSD and
NeXtSTEP for demo purposes without ever needing to change the card.

Or you can dedicate one card per OS, and easily switch from one to another
[as long as they are all configured for the same drive configuration - it's
stored
in the SCSI2SD device, not the card :-( ]

The SCSI2S is far from perfect but it's a very convenient way of
resurrecting
some old systems. But it's too expensive :-(

Cordially,
