TestDisk wrote backuped Partition Tables wrong to disk
Posted: 19 Dec 2017, 19:34
Hello,
4TB-Disk (GPT, 3 partitions, each NTFS) went corrupt, started TestDisk, said first GPT signature corrupt, read alternate GPT signature, was fine.
I backuped the working GPT signature and wrote it to disk.
System Restart.
Checked Computer Management, showed me this nonsense: The empty 128 MB are correct, the starting position of (D:) is correct too, the rest is nonsense. I'm saying what TestDisk wrote to the Disk is not correct at all.
(D:) should be around or exactly double the shown size, (I:)'s and (J:)'s Size is correct, but they should be located at the end of the disk. There should be no empty space after them.
This leads to me being able to list the files on (D:) (as the file systems starting position appears correct) but not on (I:) and (J:).
While I do not think it's simply TestDisks fault I wonder what went wrong with writing the backup to the Disk.
Do I have to check for something else before writing the backup to disk? Sector Size or something?
I'm currently unable to come up with a logfile as I'm still running a quick search on the disk.
The green entrys show the content of the backuped data, the white line is just a wrong entry after writing the backup to the disk and can be ignored, I guess. I also tried to set the "unknown"-labeled entries to GPT EFI/NTFS and also to MS Data/NTFS. Setting it to the latter one showed me the above situation from picture 1.
Really hope someone can help with this problem - it's kind of life relevant.
