Thanks for the reply. Yes, I meant to say that I tried the "fix" option in the Check Filesystem status and it didn't work. This is the error message:
Phase 1 - find and verify superblock... superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error
I also tried it in terminal with all the other -L, -V, -N options
Its also showing some Errors here:
Actually looking further, the extended SMART test is showing read failure.
