WD5000AAKS, to many bad sectors

June 9th, 2012, 21:06

Situation:
- Synology raid5 array: 4 disks WD5000AAKS
- Disk 3 crashed, and I replaced disk 3
- While rebuilding the array disk 2 also crashed.

Disk 3 seems to far gone, disk 2 still gives me SMART and the quicktest with LifeGuard (WD) and an "to many bad sectors"-error with the extended test.

I've tried to test it with MHDD, but that program stops (crash?) after on avg 1-3 exclamation marks.
It makes a sound each time it encounters an exclamation mark, a sound like "tik tik tik tssss"

I've tried to clone it with ddrescue but after a few seconds I get I/O errors.

I really need either disk 3 (but I've given up on that one because it doesn't even show SMART) or disk 2 to be working to get my precious raid array back online : (

Can someone point me in the right direction, or suggest me a affordable professional!
Thanks guys!

First of all - put the full model of your drive since the answer may vary on the drive family.
WD5000AAKS can be Tornado3D, Atlantis, Gekko, TahoeLT, etc...

I am not sure which information on the disk is representing the model so I'm writing down multiple things here:
WDC WD5000AAKS-00YGA0
WD Caviar SE16


SMART data and other results from test:

Am I missing some additional information?
Would recording the sound that the disk makes help?
It does not only make this sound when it encounters an ! during MHDD, but also once when powering the disk (starting up the pc).

Send it to a pro before it is too late.

I'm in full agreement here. Loss of two drives at once is usually not the time for some "wild and crazy repair guesswork".

It's Tornado3D. They are prone to head failure. Pro help needed.

Hi pro, I think it's T3D PMR.

Thanks for the replies guys, I guess I'll just have to send it to the professionals than, this is going to hurt my wallet...

I'm definitely going to dive into this harddisk repair business, it's the goose with the golden eggs.

Sorry, I'm not a Pro. :oops:
I don't know what PMR stands for...so I didn't put it.
