I got mine (1 and a half) for free ;-)

So you cannot read and cannot write to it.

What where the results on the mac? Can you clone the disks using a mac? If
so, what are the results?

My experience: the 712 I have at home was my workhorse for over 5 years. It
never failed on me. Occasional reboots for obvious reasons never had any
problems. However, after being down for a couple of weeks, the harddisk does
not spin properly. It was reported with several of those older systems. The
ioscan and other tools that only access the firmware of the drive report no
problems. Actual access of the disk is a problem since (in my case) the disk
does not spin at all.

If you can access the data storage using your mac, you might have success
after warming the device. I know the powersupply in the 712 series is
limited and might not provide enough power to start a cold disk. You might
be able to clone disks using your mac.

In an disk array, I have a couple of disks that are all the same specs.
However, due to a hardware defect in one of them, a (HP-UX) `ioscan` reports
0 bytes for that disk where others report their actual value. If you hook
the disk to an HP-UX machine, what does `ioscan` report?

Sorry to say but I think your disk is dead

Success
