Hi cortman,
#dumpe2fs /dev/sdb1 | grep superblock it does not work for me. its output: dumpe2fs: Corrupt extent header while reading journal superblock But, after few search, i found these two commands and my partition info recovered after trying them. #fsck.ext4 -v /dev/sdb1 #e2fsck -b 32768 /dev/sdb5 Thanks dude. |
Glad I was able to at least point you in the right direction. :)
Glad it's solved! |
