Just grab any 80-pin ultra scsi drive. Just be careful about heat
dissipation though. I just bought two 73Gb scsi drives for my Ultra 2 on
ebay for $150. Make sure whatever drive you buy that it is a 1" height
drive otherwise it will NOT fit in the drive cage. Remove the existing
sleds from the quantum drive and put it on the new drive and slip it in.
Very easy to do. IIRC, the SCSI connector is a ULTRA 160, but you can use
the higher rates as it is backward compatible. The model I bought are the
Seagate Cheetah ST373307LC (UlTRA 320 80-pin SCSI drives). Make sure it is
80-pin and NOT 68-pin!!!

Subject: OT: Help! Sun Ultra 1 HD replacement?
All,
Apologies, I'm probably at least 2 years off-topic.
Have a Sun Ultra 1 with a non-functional Quantum hard drive,
model number seems to be VK45JZF1. It's in a sled with a lever on the
front, and the connector is a funky thing with a central ridge rather
than pins. This is for a work project.
Where can I find a replacement fairly quickly?
How much should I expect to pay?
What's with the strange interface?
Replies here would be better, on-list OK.
TIA!

Incorrect. The U1 drive cage will in fact hold a 1.6" drive in the lower slot.
I wouldn't want to run a 1.6" and a 1" together in there for heat
dissipation reasons (they will fit, I've tried, but they end up *very*
close together), however if the machine only has one disk in it, a
1.6" in the bottom slot will be fine.

Not necessarily. *Some* Ultra1 systems will accept a 1.6" disk, but
some won't. That's a physical limitation of the backplane, rail guides
and SCA connector, not a question of "supported configuration".

Heat is likely to be an issue with 2 high-RPM disks, even with a pair
of 1" drives. Air flow is side-to-side, so making sure there's ample
space on both sides of the system helps quite a lot.
