Recovering data from a formatted USB Pendrive which was encrypted

I have a pendrive which I encrypted in the Windows OS using the bitlocker. Everything was perfect. I had 2 USB drives which are similar. Recently I accidently formatted the pendrive. Later I realized, the one I formatted was the one with encrypted files. I tried to recover the data using Recuva file recovery software. But after scanning, the result is blank. The software shows above 3000 files found, but empty results.

Is there any way I can recover data from the USB disk ? Or since it is an encrypted one, Should I forget the data ?

N.B : I have the encryption key with me.

By formatting the disk you have destroyed the encryption headers, and the recovery key you possess cannot help.

Sorry to say, but your data cannot be recovered.

1.First things first: Make an image of your USB flash drive!

With e.g. one off these tools:

• PassMarks "ImageUSB"
• win32diskimager (doesn't work for me anymore)
• Rufus (the image function is the floppy icon right next to the USB drive selection drop down menu)

... or any other tool recommended by Raymond (HDDRawCopy is good)

You can then play around with copies of that image with any tool you want and no further risk to the data. You can even mount those images to virtual drives (with e.g. OFSmount or possibly within Windows without 3rd party tools).

2.To answer your question

As long as you didn't write any data to the accidentally formatted drive I'm sure there is a way to recover the data or at least most of it.

3.Now to answer your non-asked question - how to recover the data

I've never worked with BitLocker before so I'm not much direct help but I highly doubt that a single quick format (that's usually what formatting is and you didn't supply enough information) of anything removes all of bitlockers key backups.

And there seem to be plenty of tools available for you to try.
