How to recover data from a deleted partition?

[Puck_Man]

A few days ago I formatted my pc, not the first time I've done it. I have 3 hdds, 2 internal and one external. I was a bit paranoid with backing up, so I backed up my main hdd on the external. However my paranoia just clouded my mind and I totally forgot to back up the second drive. I realized that after I formatted. However I had deleted all partitions during the format and installed the OS on the disk I had backed up so nothing was wiped from the second one. Using Lazersoft's recovery program I recovered the old partition and got my files back no problem. Today I decided to make my external drive internal. I thought to back it up before doing it but for some reason I was getting errors while trying to do that, windows explorer crashed once or twice. I did manage to start the transfer, it was about 20 gigs of data, but the drive uses usb 2.0 and it was taking forever. I got impatient and a bit cocky and I thought that since I'd already managed to recover data once, I could do it again should the need arise. I got it out of it's casing and removed the adapter and plugged it in, I could not access it without formatting it. I scanned it with the same program I used on the other disk but this time I did not find the files. Then I was messing around in the computer management and created another partition, nowhere in the process did it say that the disk was going to be formatted. I could now use it but the data was not there. I am almost certain it was not been formatted since I never authorised something like this and the system always notifies you when it is about to format a disk. I've scanned it again, nothing. I took it out and put the usb adapter back, still can't read it. Currently I am scanning it with the program using the usb adapter but I don't know what good that will do. I am positive my data is still in there as there has been no new data on it besides the new partition. What can I do to recover them? Some are irreplaceable and important.

EDIT: I gave up and went through the process of making a new partition. Turns out it does format the drive when you do it so I formatted it at least once by accident. Oh well, not much point to it now.

You could try Partition Wizard's MiniTool or Partitiion Find and Mount to possibly recover the partitions of your hard drive. But if those applications turnout to be unsuccessful then I'm afraid your last possible option would be a professional data recovery service.
