[SOLVED] Mounting USB EXT4 Partition Fails

But we might be onto something with your dmesg hint, because it says:

Quote:[ 358.756005] EXT4-fs (sda1): ext4_check_descriptors: Block bitmap for group 0 overlaps block group descriptors
[ 358.756013] EXT4-fs (sda1): group descriptors corrupted!
[ 395.164635] EXT4-fs (sda1): ext4_check_descriptors: Block bitmap for group 0 overlaps block group descriptors
[ 395.164642] EXT4-fs (sda1): group descriptors corrupted!

so there still seems to be something wrong with the FS of SDA1. But e2fsck seems not to see it. Do you know an option that can see or fix it? I have a backup of the most important data on the partition, but I would really like to try to fix this somehow...
Also, I don't know how it even got corrupted...

Hmmm, that's a good question. Can you narrow down when mounting sda1 fails. Perhaps after a kernel upgrade? Maybe the kernel you're running now (4.14.58+) can not mount this partition, but prior version does

Can you run e2fsck with parameter -f again, to force check again and see what happens?
