Recovery of a Partition Table that was Eased by Testdisk
Posted: 05 Jul 2014, 12:23
With the Windows Disk Management Utility I erased the Partition “Lab3_F” of my 3 TB hard disk.
No further actions took place.
Afterwards I used Testdisk to recover it:
That time Testdisk showed both partitions “Lab3_D” and “Lab 3_F”.
My intention was no changes on "Lab3_D" and a recovery of "Lab3_F".
Due to a misunderstanding of the Handbook I marked only the partition “Lab3_F” as “Primary” and left the other entries open. I assumed in TestDisk no marks means no action. That was obviously wrong.
After the succcessful recovery of “Lab3_F” my partition “Lab3_D” was gone !
No further actions took place.
Now the Windows Disk Management utility shows: The normal search with Testdisk showed overlapping partitions, so I ran a deep search which took some days: or as a text:

My questions are:
Where is the obviously active Partition “Lab3_F” in this table?
What next action do You suggest to recover ”Lab3_D” and to keep “Lab3_F“?
