I have an 8TB external HDD formatted as ext4, one single partition per gparted. I do NOT have any data on it at this time that I care about, so there is no issue of extracting data from it.
The drive began to act strangely - e.g., it would take a very long time to save a very small file to it. Using gparted I created a brand new ext4 single partition on the drive, thinking that mighy magically make the problem go away. But it did not.
When I run fsck on the drive, I get the message that the superblock has a bad magic number, and that I should restore that superblock with a good magic number from the backup superblocks. However, every one of those backup superblocks also complain that they too have a bad magic number.
What does this tell me about this drive?
How can I fix this problem with the superblocks so I can continue using this drive?
