Unable to list or recover from volume

[matthewcmead]

I have a volume in which /Users/ has disappeared. I can search the volume using the search command (recompiled to have a list of names I'm interested in) and find various matches which make me suspect the data is still in the volume.

When I attempt to list anything on the volume by fsoid (found from search) or by path (e.g., /Users/) I get the following:

• Volume 0 has Virtual OID 0x6400000000 ... END: No objects with Virtual OID 0x6400000000 and maximum XID 0x915 exist in nx_omap_btree.

Any ideas on how to get to the point I can list / recover from this volume?

Thank you!

This means that the object map of the latest transaction doesn't contain any records for the object you're interested in, and you'll have to (1) explore an older transaction and/or (2) scan the entire disk for object map records that you're interested in. These are tasks which Drat currently isn't capable of (hence me closing this thread), though I would like to add these features.

For now, you may be interested in alternative software like Disk Drill, which is capable of (2).
