Undelete HFS+ partition

Using Windows 7 storage manager I accidentally deleted my hfs journaled partition containing a lot of precious iMovie data.
I would like to "simply" undelete the partition.
Nothing at all has been touched on the ruined disk after the mess and I've cloned it onto another disk so I can try recover without messing the original disk.

What should I do?

Any kind of tool for any kind of operating system that will allow me to recover data (and, possibly, folder structure) is incredibly welcome.

Free to try.  You pay for full functionality.

The best data recovery available ... free to try and find out if your data is recoverable, then you will need to buy GetDataBack to complete the recovery.
I have used it to successfully recover data where other data recovery has failed.

If you want to try to recover the partition then use:
"Partition Recovery Wizard"
Mac supported

Other recovery software:
"Get Data Back for Mac"

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

You deleted the Mac partition on Windows and you have made a clone so try to recover the partition on both the Windows PC and also the Mac.

If the partition cannot be restored in full then try to recover the data on both the Windows PC and also the Mac.

One or the other should work.
Good Luck.

None of this solution got my data and file structure back...

The opensource called Testdisk did this in 5 minutes: great great software :)

It was as simple as:

a) Clone the disk (just to be sure)
b) Find the lost partition with testdisk and restore it
c) Resize the partition of a very tiny bit with standard Mac Os X disk utility (otherwise the pc won't boot with the disk attached: strange, uhu?)
d) Reboot and live happily everafter
