Corrupted super block
Ok, so this is driving me nuts. I had to hard reboot my machine and now I have superblock issues on my boot disk. I have a Lenovo u310, which comes with two drives, a little ssd, and another 500gb. I installed Ubuntu on the ssd and put my home on the 500gb. From everything I can see, the big drive is fine (thank god), but the ssd is having superblock/journaling issues. When I reboot and try to run from the ssd, it gets through grub then throws an error along the line of “error: failed to write to sector 0x0938e9.
I’m currently running off a live usb, and I’ve looked around and found what I could but nothing seems to work. I’ve tried going through the process of updating the superblock from a backup from here. But each one of the backups I try says the same thing:
e2fsck 1.42 (29-Nov-2011) e2fsck: Bad magic number in super-block while trying to open /dev/sda1 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>
I almost tried running mke2fs -S -B 4096 /dev/sda1, but it sounds like I should save that for the very end.
I’m not trying to retrieve the data from this drive. I just want to do a clean install of Ubuntu but I can’t because of these errors. Is there some way to just wipe it all away and start fresh? Everything I’ve found for wiping superblocks is mdadm raid stuff.
