Windows 7: Drive became Unallocated and not having much luck recoverying

Fully understand and already feel guilty taking up so much of your time. I'm very grateful for the help and whatever speed / time you take is fine with me.

This is what the Hitachi reads but then so do all the other partitions on the 2TB WD / Toshiba and SSD drives. So it looks like it is correct



Sectors per Cluster: 8 (4096 bytes)
Sectors per File Record: 2 (1024 bytes)
Sectors per Index Record: 8 (4096 bytes)
$MFT LCN: 786432
$MFTMirr LCN: 2

Ok I've installed v9 but don't see any extra information.

I might be getting confused here.
1) If I click on the left (disk icon) > properties
I get disk properties which shows 'Bytes per sector' = 512

2) But if I click on the partition > properties > filesystem info
Then I get 'Sectors per Cluster 8(4096).

So I'm not sure which information applies to Blocksize.

I'll post v9 when I've done the first one

You do see some extra Information. See the Disk Map. Below the Disk icons in the disk map it reads "Basic MBR (Disk size)" Earlier versions it is only "Basic (Disk size)" So the disk map will now show whether it is an MBR drive or GPT drive.

I am also getting confused. I would think that block size refers to sectors/cluster If so I would think what was indicated by TestDisk as Block size 4096 is correct. (.(It is always confusing terminology when it comes to HDDs the more deeper you dwelve into it the more confused you will become).

But don't worry. We shall find a way to put it to rest and proceed.

Run TestDisk

1. No log
2.Select your Hitachi 1TB Disk - post screenshot
3.Intel
4.Geometry - post screenshot
Quit Test Disk

Not to get confused now "safely remove" your Hitachi 1 TB drive from the enclosure and keep it aside safely.

Plug in your faulty WD 1 TB drive into the slot where it was originally in the enclosure.

Run TestDisk
1. No log
2.Select your WD 1TB Disk - post screenshot
3.Intel
4.Geometry - post screenshot
Quit Test Disk

If sector size in both are 512 Bytes, we are clear.

Then we shall proceed with TestDisk on the WD 1 TB drive tomorrow.

I shall see the screenshots after another 8 hours tomorrow morning. You can also go to sleep.

NOTE: Do not make any changes to Geometry. Just quit TestDisk without making any changes in both cases.

Yes they seem to be identical > top is the WD bottom is Hitachi. So hopefully looking good.

The expolaratory work is over. Confirmed that there is no GPT and the block size 4096 refers to cluster size. (Windows 7 and 8 can read 8sectors (4096 bits at a time))

Now we shall go back to the your post#5 (where we branched off). When you come to the screen you posted there, press P (Capital p+Shift) and check whether your folders/files are listed. If listed copy a few files to a folder on your internal drives ( but not system drives) and check whether everything is OK.

If you encounter any problems post with screenshot.

Good morning! :-)

Ok, I'm starting the scan.

As I remember pressing any of the letters didn't do anything last time perhaps because the only thing listed was:

* HPFS NTFS ....

Where their example shows that some other partitions should show up like

D HPFS NTFS ......

TestDisk Step By Step - CGSecurity

As I understand it the partition marked with *
is the backup copy of the partition information found at the very end of the partition. So it appears that the main copy is damaged so badly it can't even be detected.

What worries me at this stage is that the files I recovered are far from complete. There are quite a lot of files I wanted which are not there so I am thinking the damage is might be too bad.

Anyway not much I can do about it so the scan is 43% at the moment. I'll be back when it's done.

Scan is done but 'P' option leads to this which says filesystem is damaged

EDIT: I had written this post before I saw your previous post but still holds.

1. How many partitions did you have on the drive

2. If pressing P, does not do anything (hard for me to believe , it should atleast give some message,) then press Enter to proceed and post the next screen.

My plan of action is as follows:

a. Run Test Disk and check whether it takes us to the write screen. I am assuming you had only a single partition which it shows after a deep scan and we should be able to write it.

b. If it does take us to the screen where we can write the partition table, then we shall quit TestDisk

I would like to examine Sector 0 where the partition table normally exists with bootice and save a copy of it before writing the Partition Table with Test Disk.

If you want you can do this bootice saving first and then run TestDisk to write the Partition Table at sector 0

Bootice: You will install Bootice x86 if your system is 32 bit or booticex64 if your system is 64 bit.

Post a screenshot at Sector 0 so that I can examine what it contains in the Partition Table area and also save it. By default bootice will save it its folder.

Saving with bootice: Lost partitions!

After writing the partition table with Test Disk, again post a screenshot Sector 0 with bootice and also save it.

Once we have written the Partition Table with TestDisk, we shall restore the NTFS Sector from its backup.

Barring unforeseen events, your drive should get restored. Let us hope so.

Couple of things worth tying.

1) Partition recovery :

Try some other partition managers,they are not all the same.

Part Assist might come up with something, worth a go.

Download Free AOMEI Partition Assistant Standard - Magic Partition Manager Freeware

PGuru is an advanced tool . Free version partition recovery functions work, but the data recovery stuff only activates when you have a license.

You may find the partition recovery on that will do the job.

Free partition manager, file recovery tool and Windows backup software - PartitionGuru Free


2) If you are unable to recover the partition, then you can try data recovery:

Recuva is worth a go.

Just the one - the screen before pressing P is exactly as in post #5

After pressing P is the screen I posted - Filesystem damaged

Well I am back on the partition screen. If I press ENTER: to continue then I will get two options [write] [quit]. However, last time I did that and then pressed quit I lost the option to go back to the scan screen. I will have to scan again.

Ok so I am going to exit from Testdisk and will install bootice ...
