So fsck tried to read part of the filesystem and got an IO failure.

Messages coming back from the IDE driver indicating fatal media
errors: you've got bad sectors on the disk.

IDE passes the error back up to the filesystem...

... and the filesystem logs the failure and passes EIO back up to the
calling application.

The kernel is working exactly as expected in the presence of
unrecoverable disk failure.
