Back to topic:
If you have Quarterback Tools in DH0 (system, _HairyDave_, AnyOtherName, whatsoever), I think is that obvious the man who maintain the Amiga before (rest in peace) use it to do the backup files.
Then it's simple:
- Find the quarterback tools drawer (name of directories on Amigas;
- Open the rescue utility (I forgot the right name);
- Make the rescue app scan the DHx: (the lost partition).
- Point another partition to do the salvage (be sure you have enough space in the other partition, of course;
- If you get a message like "archive xxx is damaged, it won't be recovered", stop the scan and quit the application;
- Wait until someone who have an expertized knowledge in Amigas arrives to do the job for you;
- In the case the last sentence is true, stick with him/her in order to know a bit more of this wonderful piece of OS. ;-)
