recover data from formatted HDD

can i use recuva to do this ?

original partition - full drive space - mac os journaled

new partition - full drive space - FAT32

the drive hasn’t been touched since it was formatted (ie no files added or removed), it’s still an empty FAT32 partition.

using windows 7 to try and get the data off it.

So it was a Mac file system and it was formatted as FAT32? I don't think that Recuva will recognise any Mac directory strictures.

You could try a scan, it won't do any harm. Run a deep scan: this won't find fragmented files, but you might get something. Or look for any Mac recovery software.

it was previously a mac formatted drive, with all the data

it was then formatted to fat32
