Stop using the system. Take it to a data recovery service.
It's an expensive thing to do, but is the surest way to get around the problem, and even then there's no guarantees. I'm sorry, but formatting wipes the drive clean. Luckily, it does not overwrite all the information on the drive, it simply removes the ability to access it, so any of the storage area which has not been overwritten since will actually still contain data, and it is possible to lift that data off.
Unfortunately, the fact that the drive has been converted from FAT32 to NTFS as well leaves me with little hope, and I'd be reluctant to even recommend one of the downloadable data recovery programs that can be found available, in order that you might try to get it back yourself. I really think the best option is either a professional service, or simply 'biting the bullet', contacting management with the problem, and getting that Document folder and its contents put back on your machine again by them.
