I deleted a NTFS partition and quick formated it.  I need to undo the actions.  Is it possible?

Chances improve the less things have happened (written data on) to the drive.

Try this - it has a demo:

Apparently around the net people have been able to use the following software to recover lost partitions. I wish you luck as I thought there was no easy way to do it.

Before following the advice given above by rnicolaus for a commercial tool, I'd suggest you try the free version of that tool first:

Here are instructions on how to use it for unformatting Ntfs:

thanks for the input Torimar - like I said:

"it has a demo"

I read and understood what you said.

The commercial versions of that software may also be downloaded and tried: those are "demos".
What I linked to, is the free basic version of the software which is fully functional and does not need to be registered or bought.

Sorry, but for me these are two very different things.

Although it is 'fully functional', the free version states it is limited to 1GB.  Assuming that usable partitions in 2011 are >1GB I don't think that would be of use to him - even thought he didn't provide the actual size.  The question was "Is it possible?"  Which it is, and I provided a solution to him that he can try before he buys.  It was not "Is it possible with a free tool?"  Which I believe it is not.

I am aware of the 1 GB limit, but so far I interpreted it as referring exclusively to active file recovery.
Whereas 1 GB could contain quite a number of documents and data, as a filesystem limit it would render the software completely useless for unformatting, because '1 GB or less' that's the size of partitions or drives we had 15 years and more ago.

But I admit I do not know from personal experience, so I can only strongly assume it might work.

Apart from that, it should very well be possible to undelete a partition with free software if one uses TestDisk:

I did not mention that before because this is a graphical command line program originally developed for Linux, and therefore somewhat difficult to use for Windows users.

I understood from the very beginning that there was a DEMO version.  So quit kicking sand on each other.  My real problem is an entire partition recovery.  

To add insult to injury my client deleted key files then reformated.  I ran the DEMO and found the deleted files, but the recovery found 0k.  There are 2 files in the RAW data and the suspected file is 2Gb.  So now the delema of $70 and still zero recovery.

Any other ideas?

vic45708 -

Sry - unprofessional of us.

The only chance I know of is a utility like this.

If it makes it easier to take a plunge, they do have a money back guarantee - found on this page:

"EASEUS also provides a 30-day money back guarantee if you are not satisfied with its products. Just try it to recover files after format."

Download and install trial version of this tool:
Then run it - select Full Scale Launcher mode where you can see your disk layout. Delete partition (you quick formatted) and then right click on free unallocated space. Select Recover Lost Partitions. Specify NTFS partition search. It could find several of them so you need to detect your partition according to the used space on it. If found restore it.
No payment is required. This trial version will restore it if possible.

Although there is some controversy about the demo mode, the demo mode allows you to see what is available to recover.  The use of RAW data allows you to even recover files that were deleted on the reformatted drive - "Cool"
