Hi ToowoombaLexus,

Welcome to SevenForums.

I am literally confused.

That is long thread with 110 posts. I don't remember even a bit as to what I had written in it. I have no patience to look back into it.

Can you please tell us what exactly your problem was and what exactly you picked and used from this thread to have successfully recovered your data?

You have only posted the PRW in PW running a scan and it is just started. Even if it completes and successfully finds and writes the partitions your whole drive would have come back alive as it was before and there will be no need to save anything.

But you are saying it is saving something now.

Thanks Jumanji
I have 2 x 1tb sata hardrives that were not showing up in My Computer. However, in disk management I could see the drive being labelled as "unallocated". After hours of searching forums I stumbled upon your post and followed your instructions to the letter.
I think you nailed it when you said its the first initial sector that was preventing the os from reading the drive. All my pics and movies are there but the os just couldn't read the "unallocated" drive.
By "being saved" I meant the software (PW) is doing exactly what it promises to do.
Thank you again for the great step by step guide / help.

to be more specific:
I have a sata dock which I use to access half a dozen external drives. 2 of these drives mean a lot to me. they are both 1TB WD and somewhere along the line there must have been a power failture or surge while the drives were in use. So when I plug in the dock and put drive in, I can hear the drive powering up and turning and all dock drivers etc are working fine but just could not access / see these 2 drives anywhere except in Disk Management in device manager as seen in pic. It was really pissing me off as I had never experienced this issue before and clueless (I'm less than average computer literate!)
My pc specs are faily respectable and I dont have any dodgy software and religiously run kaspersky Pure. So i couldn't see any reason why the drives would not show up in My Computer. I had never heard of this Unallocated and bad initial sector before. Previously if I had a dead hard drive, It either had no power or made clicking sound and good as a paper weight. But I knew this wasn't the case with these 2 drives so i started searching forums and came across your very helpful post/reply.
Hope that makes sense!!

Oh! Good. Glad this thread was helpful and you could help yourself. ( I also remember that I had mentioned in one post that this thread is almost becoming a reference, though we couldn't resolve the OP's problem.)

Please do not tag on to an old thread. If you had picked up some useful method and that resolved your problem its OK. But if it didn't help, there could be various reasons. So you will be better off starting a new thread and presenting your problem ab-initio.

In the new thread please give all details of your problem drive Internal/external ?, manufacturer/model Number, Capacity? age? and also from when this problem started, whether it happened all of a sudden or whether it was gradually deteriorating etc.,

Also post a screenshot of Windows Disk Management and and the first screen of Partition Wizard. No overlapping screenshots that obscures the first screen.

From what I see your drive has turned Read Only. Not a good sign. You may have to run the manufacturer's diagnostic/repair utility, may be WD Datalifeguard Diagnostics for Windows and check the status of your drive.

May be since it is a WD drive, CKWD - the WD man here - can help and a new thread that starts with
" My Western Digital My passport..........." will catch his attention.

Hi Jumanji,

Can I please seek your help?

My WD Elements is also shown as unknown and not initialized in my Disk Management, but I do not see the unallocated message on the right hand side.

I do not know how to post image here (how to attach pic by URL?), so please advise on this so I can post my pic.

Many thanks if you can help!

When I go to Computer Management, under Device Manager it only shows as Disk Drive and in Disk Management it comes up as "Disk 1, Unknown, Not Initialized".

I've uninstalled the device, then plugged it back in. The "USB Mass Storage" driver installs but then the "Samsung Portable USB Storage" always fails.

Anyone have anything that could possibly help please? I have a lot of data on there, but it's only the pictures that I really am after!

HI Jumanji,

I just realized I am facing same problem as IraajV, but no solution has been provided to him/her.

I posted a new thread on my specific issue (I think its the same as the OP) here:

hard drive is no longer initialized windows 7

FYI, I could not directly download the software mentioned, but at the site linked I was able to find the software. Be sure you download a file called: pwfree91.exe

That is the software mentioned in jumanji's post #3 above.

MiniTool Partition Wizard Home Edition is now christened MiniTool Partition Wizard Free Edition. The link in my post #3 will still take you to the right place but don't search for Home Edition. Download the Free Edition, the very first on that page and it will download from Cnet.
