Help!!! Error 18 - Selected cylinder exceeds maximum supported by BIOS

Hi,

I ran fdisk and here's what it shows:

ubuntu@ubuntu:~$ sudo fdisk -lu

fsck.ext2: Is a directory while trying to open /mnt

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>

/dev/sda1: Attempt to read block from filesystem resulted in short read while reading block 59507202

/dev/sda1: Attempt to read block from filesystem resulted in short read reading journal superblock

fsck.ext3: Attempt to read block from filesystem resulted in short read while checking ext3 journal for /dev/sda1

ubuntu@ubuntu:~$ nautilus mnt &

ubuntu@ubuntu:~$

I still don't know what to do. I already checked the post http://users.bigpond.net.au/hermanzone/p15.htm#18 and that's how I got stuck with Gparted while trying to create a separate boot partition.

Yep sounds like your data needs fscking. Boot to live cd and check the partitions. There are errors on the data

use:

sudo fsck -a /dev/sda1

This will automatically fix stuff. When it finishes, reboot and remove the CD and see if it boots ok.

Hi,

I ran fsck -a and here's what happens:

ubuntu@ubuntu:~$ sudo fsck -a /dev/sda1

fsck 1.41.3 (12-Oct-2008)

/dev/sda1: Attempt to read block from filesystem resulted in short read while reading block 59507202

/dev/sda1: Attempt to read block from filesystem resulted in short read reading journal superblock

fsck.ext3: Attempt to read block from filesystem resulted in short read while checking ext3 journal for /dev/sda1

Now if I try to boot from the Hard drive I get a message "Operating system not found". More ominously the BIOS does not recognize the hard disk drive any more!

Best regards

Ludmil

If the BIOS doesnt see the drive then its a hardware issue. Check the connectors are in good (Power OFF the system before playing around)

Sounds like the IDE has failed in some way to me, if all cables are connected then the drive has probably died
