Posted: 14 Mar 2019, 05:37
I have a situation where i ended up overwriting my main ssd of the workstation. Below is the chrnological order in which the system-partitions/ file-systems were created.
PROBLEM BACKGROUND/HISTORY
GPT partition with 0%-33% , 33% to 66% and 66% to 100% partitions all btrfs type. some important data was stored in this partitions ( from here on refered to as the data
I accidentally overwrote the whole disk with a new partion table and partitions , (2 to 3 times ) each partiton of 0 to 3% and 4% to 100% of GPT type and of FAT32 and ext4 file-systems respectively.
ISSUE:
With the above issue at hand i am trying to restore back to GPT - btrfs partitions mentioned in point "1" above
After initial research i am trying to use the testdisk software to restore back the deleted partions.
However upon selecting the particular partion to restore as listed below.
If I press "P" at this point (as per the instructions on the test-disk website), i see the below screen. TestDisk 7.0, Data Recovery Utility, April 2015 Christophe GRENIER http://www.cgsecurity.org
