2TB HDD only shows 6KB

Bandera_Bulldog · Apr 13, 2014

So, this description may be a long one...

First, the HDD info:
Brand: Seagate
Model: ST2000DM001
Controller Board: 100664987 Rev A
Capacity: 2TB

A family member (who is an author) recently had their HDD fail with many chapters of their book stored within the drive. Since I'm a EE, they figured that I should be able to fix it. I made no promises, but took a look at the drive. Here is what I have seen so far.

In Disk Manager, the disk shows up without any space that can be allocated or any volumes. Thus I am unable to assign drive letters and the like. As the subject mentions, when I look at it in the DiskPart utility it only shows up as 6656 Bytes. I've used a hex reader to open the disk and it shows the MBR only with a total sector space of 13. Based on the research that I've don and having little to no knowledge about Hard Drives my only guess is that something is wrong with the controller board and the ROM needs to be transferred to a donor board. The HDD does not make any "clicking" sounds and seems to spin up fine. One last detail, I've used Seagates tools and found that it passes some of its SMART tests, but fails some others. I'm not quite sure which ones specifically.

Any help or insight would be greatly appreciated.

First of all, do not do any write operations to the drive. Don't create a partition, don't format anything, don't change any bytes on it. That can only make recovery harder. The usual first attack is to assume that this is not a hardware failure (especially the controller logic which usually takes a professional to fix) and run recover utilities against the drive. These will scan it sector-by-sector and try to recover files and, if possible, the disk structure.

Two problems with my answer. First, a lot of the commercial spam on the forums is come-on for data recovery tools which aren't worth the price and may not work at all. I've got links to two threads with good lists, but those links aren't with me now. I'll look for them and try to update this tomorrow.

EDIT: Recuva is a well-known tool, and I consider it bad news that it didn't help. My list is below. fzabkar has chimed in, so you are in good hands.

Thanks for the quick reply WyomingKnott.

I have also tried a few recovery tools, which I have listed below:

Seagate File Recovery for Windows
Recuva
Yodot Hard Drive Recovery
Active@ File Recovery
TestDisk
PhotoRec

Unfortunately, none of these tools were able to recover the data successfully. TestDisk and PhotoRec require the drive space to show up correctly. With the other aforementioned tools, they only scan the 6KB that I mentioned previously. Of course, I will be more than happy to try any of your suggestions.

Can you show us a CrytalDiskInfo report for the drive? This will tell us the actual capacity that is being reported by the drive, and it will also give us a SMART report.

Secondly, can you show us the hex contents of sector 0? I like DMDE (freeware disc editor), but any disc editor should be fine (in readonly mode).

BTW, the PCB appears to be OK, and the fact that you can read sector 0 suggests that the problem is most likely logical rather than physical.

Thanks for the reply,

I downloaded Crystal Disk, unfortunately I don't seem to be able to post pictures in this forum. When I try to post the pictures, the webpage only asks for a URL. I copied the text from the report though. I apologize, as it may be cumbersome to read.

I see that the "actual" space seems to be very different from what a lot of the software recovery tools detect. I'm wondering if I need to modify the MBR section to get the drive to see the rest of the space. However, I will hold off and eagerly anticipate any insight. Thank you very much for your time thus far.

The readout of the Hex Reader is posted below for your reference. All the sections where the disk specifies the sectors and active partitions are blank...I'm not really sure what to make of that.

Sorry, I didn't get an email notification of your reply.

Anyway, your drive has serious media/head problems.

05 _56 _51 _36 00000000E210 Reallocated Sectors Count
BB __1 __1 __0 000000001DC9 Reported Uncorrectable Errors
C5 _58 _43 __0 000000001B70 Current Pending Sector Count
C6 _58 _43 __0 000000001B70 Uncorrectable Sector Count

There are 57872 (= 0xE210) reallocated sectors and many more pending reallocation. The actual number of bad physical sectors is probably 7234 (= 57872 / 8), but that's still a large number.

The capacity that is being reported via the Identify Device command is 0xD sectors. Words 60 an 61 report the total number of available sectors for 28-bit commands, whereas words 100 - 103 report the total number for 48-bit commands. Both values are 0xD, ie 13 decimal. That corresponds to what you have found.

Sector 0 shows normal MBR code, but the partition table has been zeroed. ISTM that the drive has been initialised.

I would suggest that the drive be removed from the USB enclosure and connected directly to a SATA port. That should circumvent the bogus capacity report.

I would then attempt to restore the full native capacity of the drive using one or more of the following tools:

HDD Capacity Restore Tool:

HPARemove v0.1 for Windows:

HDAT2/CBL Hard Disk Repair Utility:

http://www.seagate.com/staticfiles/support/seatools/user%20guides/SeaToolsDOSguide.EN.pdf

The reason for the reduced capacity may be a HPA. This sometimes arises as a consequence of an Asus or Gigabyte BIOS bug.

Once you have restored the drive's full capacity, you could then use DMDE or Partition Find & Mount to locate your missing partition(s).

Greetings,

I tried the HDD Capacity Restore tool. Upon start-up of the program, my computer says "error opening driver" and the program opens. Next, a bunch of gibberish appears on the screen. Since it is a 32 bit program, I ran it under compatibility mode. However, it still did not work. I opened up the compatibility tool on Windows and attempted each opening option (Windows XP, Windows 95, etc.) to no avail. I think I could get the data off of the drive if I could just get it to report the right size. Any advice?

None of those capacity restore tools will work on a drive that is behind a USB-SATA bridge. You need to connect the drive to a SATA port.

Alright, I don't suppose an eSATA port would work, would it?

I can't see why eSATA wouldn't work.
