Put on your thinking caps- 1TB external shows as 2TB in Testdisk?

…I cannot access this drive, at all. I've run a considerable amount of recovery programs at it- in the original enclosure, in another Essentials WD enclosure, bare & attached SATA to both MS & Linux….

Testdisk via Linux Mint sees it as:

Disk /dev/sdd - 2199 GB / 2048 GiB - CHS 2097152 64 32

It is a 1TB WD Essentials desktop drive.

Any ideas? Besides, "it's cactus", I mean?

Not mine, btw- it's for friend…

Any uber-smart data reclaimers here?

Ta!

  • try smartctl -d sat -i /dev/sdd to get some more detailed info?

      • Sure you got the correct device?
        Use the appropriate SMART passthrough: http://www.smartmontools.org/wiki/Supported_USB-Devices

        If you have it connected directly to a SATA controller, omit the -d sat, that'll give you the correct information.

        • I've already placed it back into it's enclosure. Running smartmon now, I get:

          smartctl -d sat -i /dev/sdd
          smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-37-generic] (local build)
          Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

          Smartctl open device: /dev/sdd [SAT] failed: Permission denied

          The weird thing is that it's still reporting itself as a 2TB hdd when it's actually a 1TB?? The reason I removed it from it's own enclosure was because I happen to have a 1TB Elements (that's what this is, not Essentials) & thought I'd give it a go attaching it to that enclosure's usb to see if it changed anything— nada. It even still says it's 2TB!!

          Now, I plugged it back into Mint & Gparted says this:

          I'm perplexed?

  • Try HDAT2 its on hiren's boot disk

    http://www.hiren.info/pages/bootcd

    good luck !

    • I do have a recent Hirens- I'll give it a go. Ta!

  • Try 121601 255 63 [512] for geometry in testdisk.

    • When/where does this option appear? WHat steps, if you can?

      Ta!

    • Where did you find this geometry to try, btw? I'm interested…

      :)

      • Take it you figured out how to use custom geometry? (http://www.cgsecurity.org/wiki/Menu_Geometry)

        You should at least be able to discover the existing partitions. I have a WD 1TB Green and suspect similar models share the same values. Google also confirmed these values for others with varying models of WD 1TB drives.

        • Yeah, I did. I used your figures, but even then, I get "read error" when I fire it up. The geometry change doesn't "stick" (I thought it might) on a retry after shutting off terminal…tried a few more times, same thing. It doesn't see any partition/data…I may have to accept defeat.

          Thanks everyone!
