Until you can do something which PROVES that the drive is dead, do not
assume that it is. It is best to approach these things as methodically
as our fallible humanity allows.

Does the drive spin up? If so, is it clicking? If the drive comes up
without smoke and is not making "weird" sounds, then try the USB 2.0
connection. I've had enclosures on which the firewire failed but the
USB port still worked.

If the only computer you have is only USB 1.1, try it anyway. You are
not going to use this connection to move large amounts of data, just
to see if you can access the drive via the USB port.

If both Firewire & USB fail to work, pull the drive from the
enclosure. If possible test it by connecting it to the SATA port of
(another) computer, otherwise try a different enclosure as suggested.

As for  "I sort of presumed one might see some sort of weirdness or
gradual malfunction", yes, that is what the SMART data is for.
Unfortunately, I don't think you'll be able to access a drives SMART
values using the Newer Tech Mini Stack. I believe it has to either be
directly connected to a computer via SATA or you need to use an
enclosure with a more recent USB chipset.

My commiserations:

Do not assume the demise of the Seagate drive, yet.  The NewerTech/OWC 
miniStack enclosures can be very problematic.  

If you have another external drive enclosure, or a drive docking station, or a 
USB drive adapter,  or another Mac, into which you can install the Seagate 
drive without too much work, check it out.

Several years ago, I had three consecutive bad miniStack enclosures within 
weeks from OWC Customer Service, and ended up contacting Larry O'Conner, the 
OWC owner, for recourse.  Earlier this year, when NewerTech/OWC came out with 
the new miniStack Classic, I ordered one to see whether they had improved 
design/quality.  It lasted about 20 minutes before the power connection/switch 
gave out.

Dead Seagate

2013-09-07 Thread Cliff Rediger
Have a 

**Seagate 9SL154-302 ST31000528AS Barracuda 7200.12 - 1 TB SATA II

in a

Newer Tech Mini Stack v 2.5
I/O 1394A+USB2.0+HUB

Not that it matters, but  running 10.4.11 as a Mini external boot drive to 
run PPC apps.

One morning... NOTHING. Suddenly, drive is not recognized at all.

 I lost some files as I'm not too diligent about backup but not a disaster.
This is my first HD failure. I sort of presumed one might see some sort of 
weirdness or gradual malfunction.
Should I disassemble the Mini Stack and check for connections?

I did reverse and then swap fireware cable but did not change power brick 
as it fires up, makes usual startup wine, light comes on, i.e. makes 
familiar noises.

Recommendations and commiserations welcome.
