hard disk failure

[Michael Havens]

okay....  I ran fsck /dev/sda1 but it comes back with

  fsck.ext2: unable to set superblock flags on ubuntu

ext 2? that's not right. I think it is ext 4.... maybe 3
so I sat here and thought I would try fsck.ext4 and it is a program.....
hmmmmm so it says that some group ddescriptors are wong and I have it fix
them. then it checks some things (inodes, blocks, and sizes; directory
structure,; directory conectivity; reference counts; and finally summary
information). then it asks if it should fix the wrong free block count for
group 0, then group 1, then group 2....... and it goes up to about group
100 (some groups are okay), then it  just starts scrolls up into oblivion
with a bunch of numbers surrounded by brackets and separated by dashes. No
matter which fsck I use  (ext2,3,or4) it is the same.
