I have the following problem while trying to access and resize a partition on my external hdd which contains Kubuntu 18.04 Lts. This problem occured after I accidentally removed the disk from my computer. I got the following output when trying to resize it from 465.24 GiB to 74.62 GiB.
Command: e2fsck -f -y -v /dev/sda2

/sbin/e2fsck: Inode checksum does not match inode while checking journal for /dev/sda2
e2fsck: Cannot proceed with file system check
