First of all, thanks a lot for this forum and for any clue that could be provided as I'm all new to this utility and kind of issues.
The issue is on a raspberry disk which was created by the raspberry imager on a microSD card.
It used to display two main partitions:
bootfs
rootfs
The rootfs partition somehow got corrupted.
Now, when reading the card with a usb card reader on a different linux system, the first partition and its files are still readable but the second partition is not recognized and not even mountable any longer.
The objective is to recover this partition - and its files...
I followed the step by step document but I'm struggling to recover the partition as quick search and deep search don't find the expected partitioning.
Also, the raspberry partitions look a bit odd.
I created a new raspberry system with the raspberry imager to be able to compare. It's created on an sdcard with the same capacity and same manufacturer so it's expected to display the expected partitioning info...
Testdisk gives the following information "Bad relative sector" for the clean new disk using the default "intel" setting whereas the system does work (ie it boots correctly in a raspberry device and the filesystem is ok):
Code: Select all
Current partition structure:
1 P FAT32 LBA 4 0 1 259 63 32 524288 [bootfs]
Bad relative sector.
2 P Linux 260 0 1 60905 63 32 124203008 [rootfs]
Bad relative sector.
No partition is bootableAlso, I don't understand the superblocks structure of the raspberry as it lists only "superblock 0", so it is unclear which superblock would have to be recovered when this step is reached:
here are the superblocks of the second partition of the clean new system:
Code: Select all
Ext2 superblock found at sector 21233664 (block=2654208, blocksize=4096)

Linux 10628 0 1 71273 63 32 124203008 [rootfs]
superblock 0, blocksize=4096 [rootfs]
To repair the filesystem using alternate superblock, run
fsck.ext4 -p -b superblock -B blocksize device
TestDisk exited normally.
So I've got two questions please:
- 1. Would it be technically possible to copy the boot sector dump of the clean new system onto the corrupted system? What would be the steps? (PSB the boot sector dumps in the testdisk log for both a clean new raspberry and the corrupted one)
2. assuming the partition info gets fixed, which superblock could be used for recovery? (PSB the superblocks analysis in the testdisk log for both a clean new raspberry and the corrupted one)
Here the testdisk log of the corrupted disk (the deeper search was skipped in this instance to focus on boot sector dump and superblocks):
