A short prologue to my Problem

DNS 320
H/W Ver:A1

Drive
Sata WD 3 Tb drive x 2
MDL: WD30EZRZ

Setup: Raid 1

One of the drives failed the smart test and subsequently I inserted a new 3Tb drive. The exact same model WD30ERZ and went through what I that was the raid recovery procedure. The procedure formatted both drives and I now have lost my data and the drives have shrunk to 800Gb.

In this Question I would like to enquire about the various data recovery tools for MAC so that I could possibly recover the data on the Degraded Raid drive that I replaced or the good Raid drive that was formatted.

Obvious preference is to find a tool that will mount the degraded drive on my Mac directly with USB SATA.

Any suggestions appreciated.

Try TestDisk: http://www.cgsecurity.org/wiki/TestDisk
You'd be looking for EXT3 linux partition.

Hi priitv8,
              downloaded Test Disk and unfortunately I don't think that USB drives are compatible. Running a MAC BOOK Pro with drives connected through a USB docking station.

Hi priitv8,
             OK looks like USB drives are supported although None of mine are showing? Any ideas?

Hi,
Haven't had a need (yet) to work with Ext3 drives, but it has saved my life once with NTFS drive and once with GUID/HFS+ drive. Both times I used this adapter:

Oh, forgot, I am a MacBook Pro user.

Reasons, why yours are not showing:
- unknown partition table (may also be badly broken)
- erased partition table

Have you tried the deep sector-by-sector search for deleted partitions?

Still no solution here.

my drive is mounted with http://www.productreview.com.au/p/icy-box-hdd-docking-station.html and I have tried two other hard drives that work perfectly well and neither are showing up in the list. In addition these same drives are showing in the Mac disk utility.

I'm going to sut down and try again. I can't find anything in the posts on the forum of test disk to support my problem.

OK I'm in.... Needed to be in ROOT to manage the drive

Needed to be in ROOT to manage the drive

My bad, forgot to bring this forward.

Last point to add is that the docking station that I was using had 2 tb limitations. I have found that most Docking stations out there have a 2tb limit. Have just bought a new one running another test disk
