Hi, I just finished setting up a multi-terabyte RAID array on my main file server, but before I could finish making the rounds and getting all the data consolidated from my remaining non-redundant disks on various systems in my network, I had a failure of a 320gb SATA disk (WD3200AAJS). This is one of the few that doesn't have a recent backup, making a recovery attempt necessary.

The specific symptom is one which I haven't seen addressed specifically after searching the archives here and via Google. Basically when power is applied, it starts to spin up seemingly normally, but after about 10-12 seconds it seems to short abruptly and immediately cycle and spin back up, only to do the same thing again in 10-12 seconds. No out of the ordinary clicking as with a stuck head. It's just stuck in a power cycling loop. At first I thought it was a power problem with the Antec external USB enclosure it was housed in, but after removing it from the enclosure then using a USB to SATA adapter and getting the same results with its separate power brick, I know it's the disk itself that is the problem and not the power supply.

I'm hopeful that a PCB swap may help in this case. The specific details...

Model: WD3200AAJS-65VWA0
DCM: HANCHTJCAN
PCB: 2061-701444-600 AD

Please let me know if you think this will work, or if there's something I haven't considered. I'm familiar with the idea of the procedure but have never had a need to do it in practice (most of my data is usually redundant).

Thanks in advance,

I vote for bad heads. You need pro help and a deep wallet. Well not deep in my eyes but deep to most people who don't like paying for a specialist service.

Thanks, would you mind giving a bit more detail on specifically what makes you look towards bad heads?

this might be the hint :

Hi,
U can try to read ROM, and the most important modules with:
Mavr_fl
&
Mavr_r

It is rather problem with SA modules (or heads) than with PCB...
PS Where are U located...?

Even if your problem was a PCB, you will have to take it to a pro anyway.
Simple PCB swap won't do a trick, because of unique microcode on your original PCB.

OK thanks. My logic was pointing to perhaps a short on a PCB trace or something, but that's exactly why I asked. It sounds like you are in agreement with the first responder.

The good news is, the data itself isn't irreplaceable or mission-critical to the point of planning an offsite recovery... more importantly than the money is time, and I can probably regenerate the majority of it in the amount of time that would take (possibly weeks?). But it's always the stuff you *don't* immediately remember was on the disk that end up getting you

Mikippp: will that even work if the disk effectively power cycles every 10 seconds? And I'm in the Boston, MA USA area.

Thanks for the opinions... any others are still welcome and appreciated.
