RAW Power does restore the data but only for drives that maintain stable “inode” values (this is a file identifier that each file on a disk gets). It is supposed to remain unchanged as long as the file is present on the drive (it will change if the file goes to another drive). It’s not a unique identifier or fingerprint. It’s just a simple number. However, some drives do not keep the inode stable (perhaps they use a different file system – not sure) and that breaks the link between the original file and the RAW Power editing data.
