Hello,
I want to recover data/partition from external disc: testdisk shows "unknown" type.
How to proceed?
Thanks in advance for helping.

Re: Unknown type
Do not choose partition type None.

Re: Unknown type
Sorry, but I still do not know how to solve this problem, even after checking TestDisk Documentation, Release 7.1.
What one should do if partition type is "unknown"?
Thanks in advance for advice.

Re: Unknown type
If you choose partition type: None, it means there is no partition, so it's useless to search for partitions...
PC Intel or EFI GPT is probably the correct partition table type.
Please copy and paste the whole testdisk.log file.

Re: Unknown type
Hello,
I chose the suggested partition type Intel. Result again: P unknown.
Then I tried advanced-file system utils
A list was displayed. From this, I tried NTFS and FAT32.
But apparently, testdisk cannot read boot sector. Should I click on "rebuild BS"?
Or, what do you recommend?

Re: Unknown type
Hello and "Happy New Year":
I provided all the requested information about my issue, but I didn´t receive any more answer. Hence, I suppose you do not "dare" to give me the answer that Testdisc does not work at least in this case. Am I right?
Sincerely, PM

Re: Unknown type
It's useless to search partitions inside a partition D:
If a partition is missing, search for them on a disk instead (sda, \.\PhysicalDrive2 or sdc).
If the filesystem is damaged, read https://www.cgsecurity.org/testdisk.pdf chapter "Repairing filesystem"
