Cannot see one (of two) partition on a USB 3,5“ SATA drive

Hard disk drive - SATA Western Digital 250GB, on a desktop PC, 2 partitions, Vista, NTFS.

Few days ago, I disassembled this desktop, and placed WD onto Manhattan SATA Quick Dock and connected it to the notebook via USB.
I can se one partition, but the other one with OS, can’t.

Tried reaching it through Computer Management/Storage/Disk Management, DM can see this partition, but with mouse right click I get only ‘Help’.

Tested for bad sectors with Western Digital Data LifeGuard Diagnostics, but everything seems to be fine (see the attached file).
Tried to connect to other PCs, still the same.
Tried other 3,5” drives to test Quick Dock, everything works just fine.

So, how do I reach this partition?
I have some data on it which is important for me…

Western Digital Data LifeGuard Diagnostics Test result

Connect this using a SATA interface, not a USB interface cable.

Try a Linux Live CD such as

Knoppix or


You can boot from the CD and should be able to access both partitions.

Or try



and see what it makes of your partitions.  Use TestDisk with caution.  As long as you use it for viewing you are OK.  If you use it for adjusting your partitions be very very cautious.

It is possible that the Manhattan firmware carves out a slice of metadata somewhere, so it does not expose 100% of the addressable sectors to the USB port.  Contact Manhattan and ask them if this is possible, or if they can confirm that their firmware would have nothing to do with the problem other than adding a simple ATA->USB bridge.

StinkyPete: If I correctly understood you, I will take my HDD to some other PC, connect it to a SATA slot and try to access it from there. If so, I will try that, and comment later since I have to find someone with PC willing to help me...All I have is notebook with USB slots and this Manhattan dock...

dbrunton: Tried to boot from CD, but doesn't sees the partition.
Why should I use TestDisk that you recommend since I used WD one (Western Digital Data LifeGuard Diagnostics) and the result is ok as you can see the attached file?

dlethe: I will contact Manhattan if the proposal made by StinkyPete doesn't work.

TestDisk is used to repair partition tables.  It is not used to test the disk.  It can find missing or damaged partition tables.

The WD util is used to test the disks as you have just done.

>> Tried to boot from CD, but doesn't sees the partition.

What CD was used for this?

     Why should I repair it if WD Test showed all is OK?
      Can TestDisk first diagnose if any repair is needed?

Can you take screen shot of Windows Disk Management with this drive connected and post it here?
Also please do not post here references to the CD you use. It contains pirated software and EE disapproves that.

Here it is, 119,26GB Unallocated.

Interesting. Can you do one trick? Download trial version of Drive Backup 10 Pro from here:
Install it and run. Does it see the drive exactly same way like Disk Management?
If yes then right click on empty space and select Recover Lost Partitions. Does it find anything? Just search, no need to recover yet.
neshasAuthor Commented:
Yes, it sees exactly as DM.
See the right click how few options it has.
Also, see in the upper window, only one 113,6 partition is shown, not the other one.

Yes.  Use it for diagnosis only.

First, the #1 rule of data recovery is STOP !!    Do not do ANYTHING that may write to that disk.

While it's sometimes true that recovery can be more successful with a native interface (i.e. SATA connection vs. using a USB bridge), your bridge device (Manhattan) is working just fine -- it "sees" the drive just fine, so it's very unlikely that connecting it directly will change anything here.

Next, the drive is almost certainly physically okay -- Data Lifeguard's extended test is very reliable.    But clearly your partition table MAY have been corrupted.    Were you using any 3rd party boot managers (e.g. Boot-It) or 3rd party disk recovery products (e.g. GoBack) with that system?     If so, it's even more important to STOP and not do anything that may corrupt the hidden "extended MBR" data that this product uses to set the MBR on bootup.

If you weren't using any 3rd party tools, download the free demo of Active Partition Recovery [  => the Windows version is fine since the drive you need to recover is an extra drive not part of the system you'll be installed it on];   run it and let it analyze your drive, and see if it "sees" the missing partition.    If so, just buy a license and it'll recovery the missing partition for you.

If Active can't recover the partition, then try GetDataBack [ ] and run it on the drive -- it can sometimes find the directory information for your files even in an unallocated space.    As with Active, the free demo download will work just fine for analysis -- but you'll have to buy a license to actually recovery the files it finds.

If you WERE using any 3rd party add-ins with the drive, let us know what they were and we can help you restore the original MBR (which will then show the actual partition information).

Did you run Recover Lost Partitions from right click? Does it find any NTFS partition?
The problem could be that enclosure and directly connected HDD report the HDD geometry in different way.

To garycase:

Actually, I did some copy-paste-delete data on other partition yesterday, whilst still not seeing the main partition.

I did not use any 3rd party boot managers or 3rd party disk recovery products.

I will try Active Partition Recovery and/or GetDataBack and get back with results...or help if needed (since I never used these tools and wouldn't like to mess up something).

To noxcho:
No, I didn't run Recover Lost Partitions from right click


Anybody: which is now wiser/safer to do first - Recover Lost Partitions from right click or should I ry Active Partition Recovery and/or GetDataBack?

I installed demo of Active Partition Recovery.
Here what came of "QuickScan" (there is "SuperScan", but I'm not sure what parameters should I choose):

In Active Partition Recovery I can see files and folders of this partition.
See the attached file.

Active Partition Recovery - right click on 'missing' partition, properties...
Gary CaseRetiredCommented:
Clearly Active is seeing the missing partition ==>  I'd simply buy a license for it and you'll have your partition restored :-)

neshas, try the Recover Lost Partition option first. This can recover the partition without need of purchase.

I tried connecting to SATA cable on mz friends PC, but we couldn't see the patrition.
neshasAuthor Commented:

Tried Recover and didn't work. See the attached file and the message.

neshasAuthor Commented:
Please, don't respond to this question anymore, because I have found solution using Acronis Disk Director Suite recommended by my friend, but I have to grade one of you since there was a collision between Acronis and Active Recovery tool.
I will get back later to you and explain and grade.\Now I have to save my data....
Gary CaseRetiredCommented:
I've not seen Active Partition Recovery fail when it can "see" the partition info.      Your screenshot seems like it's from a cracked version of Active -- if you buy a license for the current version I suspect it will work fine.

If that's not right -- and you DID buy a license -- then contact LSoft and show them your screenshot ... I suspect they can tell you which options to change to restore the partition and/or will send you the directly bootable DOS version, which can work on partitions that the Windows version has problems with.
neshasAuthor Commented:
So, I saved my data, deleted partition, formated it again, and now everything works fine.
This is such a relief...

How it happened and whom should I grade?
I went to a friend who connected my HD with SATA cable onto his PC, as firstly suggested by StinkyPete. But, this didn't give any results. My friend already had installed Acronis and Active Partition Recovery. He suggested Acronis since he is more familiar with it, so we gave it a shot.
At some point, Acronis seemed that it had finished its work with no results. So, instead of closing Acronis we minimized it to taskbar. Then we tried Active Partition Recovery and it gave an error message as show above.
We spent almost an hour googling for a solution, and finally we got back to Acronis and tried to close it. It wouldn't. It was asking to finish a pending task. So we continued and it all went well. This pending task was giving an error to Active P.R.

So, really Acronis and my friend gave me the solution, but at some point I feel like some of you did contribute just enough to be graded.

Please help me by suggesting, objectively, whom do you thing I should grade?
noxchoGlobal Support CoordinatorCommented:
I still cannot get if you did run Recover Lost Partitions option as I suggested. They are identical with acronis and do the same work.
neshasAuthor Commented:
Yes, I did Recover with Acronis.
So, you are the one to be graded, right?
noxchoGlobal Support CoordinatorCommented:
I would suggest sharing points between me and gary. We both contributed to this question and suggested the tools that work identical way.
