Quick update for everyone since I know everyone is waiting patiently... recovery attempts are still continuing, we aren't giving up yet. We've had some success with some of the smaller database files, but the largest and most important database is just over 300gb in size and it's giving us the most trouble. The file size means each recovery attempt we run can take at least 5-10 hours depending on the type of recovery we're running, so it's largely a waiting game each attempt. We'll update further once we've got something new to share. Thanks for the patience everyone.
