I have a 32GB memory stick which I have lost some important data from. Essentially whilst trying to rebuild a laptop I ran one of the utilities from the F10 screen during Win 7 64 bit installation - I think I ran DISKPART? Is that right? It was a DOS style app that allowed me to erase and I think Quick Format drives. I was trying to format another drive and not realising I had the stick plugged in I accidentally erased that one.. Ok hands in the air, I was out of my depth and messed up... now I need help to recover the data that was on the stick.
When the sick is inserted into my lapop now it says that it needs to be formatted to continue (I just click cancel here). I have tried a number of free recovery utilities to get back the data but the simpler ones don't seem to find the disk and the more complicated ones (such as testdisk and photorec) leave me feeling a little stumped. I tried a photo-rec run on it and whilst it did find a lot of files it did not correctly recover the files I am after.
The most important files I am looking to recover are some large zip files which were contained on the stick. Any help would be hugely appreciated.
