Lengthy story brief: including an APFS quantity situated on an USB disk to Catalina TimeMachine configuration leaded to begin erasing not solely the quantity however the entire disk. I disconnected the disk throughout erase operation and, since I received no errors mounting learn solely later, I am looking for an answer to get better the misplaced quantity(s) record and/or contents.
TL;DR: I’ve a multi quantity APFS USB exhausting disk which I take advantage of for varied backups (a Time Machine quantity for my MacBook16 with Ventura, one other one for backing up my iMac with Monterey and different volumes used as exterior file storage).
I needed to backup my outdated MacBook13 which is on Catalina so I made one other quantity named “TMMacBook13” on this disk.
I hooked up the USB disk to MacBook13 with macOS Catalina and began Time Machine configuration attempting to make use of “TMMacBook13” quantity as backup vacation spot: at this level I received a dialog saying that “TMMacBook13” quantity wanted to be “initialized” (translated from italian “inizializzato”, I believe unique english dialog might be “must be erased”).
Because the dialog was referring to the “TMMacBook13” quantity, I launched Disk Utility to watch what’s going to occur and I proceeded with “initialization”. On the very second I noticed a quantity disappear from Disk Utility I understood that it was erasing the entire disk and never solely the quantity so I instantly disconnected the USB cable.
Later I mounted this drive in learn solely mode on Ventura utilizing Disk Arbitrator to get learn lony mounts and I noticed that a minimum of a quantity was lacking, good luck that in mount I received no warnings relating to doable disk corruption.
Now I do know I misplaced a minimum of a quantity however, since I did not write something on it after the issue occurred, can somebody inform me:
- I am proper if I am assuming that different volumes’ contents are advantageous since I have never received warnings throughout later mount
- if there’s a technique to get the unique quantity record so I can verify how a lot volumes I misplaced
- if there’s a technique to get again / get better the unique volumes
Is there any software program / technique to get a minimum of level 2, even manually with an hex editor or a forensic equipment (even Linux based mostly)? I am not utilizing the file based mostly undelete instruments as a result of one in all this volumes was a replica of my system disk made with Carbon Copy Cloner, so it would discover 1000’s and 1000’s of recordsdata of assorted varieties.
