Accidentally formatted primary hard drive!!!

[jbrown]

MBP 2018 500gb ssd hd

High Sierra

In Disk Doctor I accidentally Partitioned my hard drive - I desperately need to retrieve data for a job interview in 24 hours. Specifically I want to recover:

My Desktop files

\less important, but desirable:

M Photos file.

Nothing has been written to this drive since the accident.

I have tried a few tools ( Techtool Pro 9, Data Rescue II, ), but they only see the empty partition created, note the root SSD where I think the data is.

Help!!!

You need to boot to another drive, and use a data recovery application like Disk Drill.

Free to try, but most recovery software costs $ to recover. Some may let you you do a small number if files for free.

With APFS, you will nee the latest version of a tool that supports it. SSDs are harder still. No backups anywhere? Shared files, emailed files?

Fortunately its not a disaster as I backed up a month ago.

But.....a lot has gone on that month!!!!

Now as I said, I realized instantly what I had done, and so no new data has been written to my disk, so I'm hoping that everything is intact....somewhere!

I've taken the plunge and bought the pro version of DiskDrill....and indeed it has found a lot of stuff recoverable.
However 90% of it I cant open ( test files, jpg, etc. ) - If I try I get a message saying that " The file is in th wrong format, or corrupted ".

Frustrating.

Any thoughts!

Looks like you're going to have to restore from your last backup.

And rebuild any files that weren't backed up.

Sorry about the data for the job interview, but my guess is you ain't gettin' that stuff back -- at least not within 24 hours.

Hmmm...

Pay attention to file extensions.

See if some of your jpegs have the exact file extenstion: .jpg

If not, append it to the name, so it is filename.jpg

If you can then open the file, you may have to re-add file extensions. Have seen that before with recovered files: extensions get removed or mangled.

Probably has to do with meta and directory data that gets whacked when formatting a volume. My understanding is that it is stored separately, and although the the files are there, the extension and/or related info can get chopped or mangled.

File names can get whacked too. Have seen folks recover thousands of images (yay!)...but they are all name sequentially, with no meta data—all that great stuff like creation/modified/last opened date and time, exposure and other camera info—so one would have to open and view and name every file (boo!).

Above my pay grade to say exactly why.....but it does happen.
