Terastation HD-H1.0-TGL/R5 drive/array failure, strange behavior?

[mwaters]

   

After a power outage, my terastation exhibited the following behavior :

Once booted, the diag system runs, detects an error in drive 3, and after 10 seconds shuts down (it is inaccessible) with 3 solid red lights and one blinking (drive 3).

 

Before the storm, the array was 90% full, which explains the solid lights.  Typically, the array should be available in degraded mode if only one drive was bad; it should not have shut down.

 

After replacing drive 3, now the diag shows blinking lights for drives 2,3 , and 4 and solid light for drive 1 (and it still shuts down after 10sec); how is this possible? At least drive 3 should be recognized...

 

I have a spare working HD-H1.0TGL/R5 and I swapped the drives into; the *same* thing happened.

 

Any ideas?  I am about to test the drives individually in a linix machine.  I can't imaging more than one drive getting fried; this Terastation was in the same power strip as several other sensitive servers.

Sounds like the raid array was corrupt.  I would try to mount drive 1,2,4 on the linux box to see if you can recover the data.

Thanks Kameran.  I've taken the drives out and found that drive 2 doesn't even spin up. (strange) 

None of the drives are recognized by Windows, but I am using a PATA controller card that I found in a shoebox so that might not be working properly.

Do you know if any of the popular RAID recovery programs ("Raid Recovery' by runtime software, or UFS Explorer) will work on a binary snapshot of the drives (using dd)?  Or do I need to .iso them or something?
