Formatted HFS recovey

#1 Postby BParrot » 08 Jul 2012, 10:31

Hi.
Please help me with my problem.

I've just formatted HFS disc with Time Machine(OS x) backups. I formated it in HFS again.

So, i tried testdisk. it found 2 existing partitions.
EFI (40 - 409639)
HFS (409640-1953262983)

After deep scaning(NOT full - only first 40cyl) it found 2 more partitions(Screenshot)

I write new map. I set 2 found partitions to primary.

BUT! After writing new map I get error, while trying mount this drive.

Can you help me, please?

P.s. I start new deep scaning.
P.p.s. I can't press P to view list of files. There is no such option.

Thanks a lot!

The problem is, HFS+ doesn't list any files.
Formatting is overriding your previous file system.
TestDisk will find only an empty partition.
In your case it's advisable to use dataracovery software.
You can have a try to use PhotoRec.

It's advisable to go into File Opt and deselct all files.
Check only needed files.
It saves a lot of time to sort files after recovery.
If you need file names and directories you should use commercial software.
