While booting Ubuntu 7.1 shows "There are differences between boot sector & its backups" hence slowing down boot process

Asked by Capslockmat1

1. While booting, Ubuntu 7.1 performs a file scan everytime and it shows following error

     "There are differences between boot sector & its backups"

2. Then it shows a long list of "Differences" like

......498:00/0d, 499:00/0a.....

3. Then it displays "Not automatically fixing this"
4. This process takes about 2-4 mins and hence making boot process slow.
5. I started getting this error when I suspended the laptop for the 1st time after installation and tried to resume. I had to restart as it did not come back from suspend. After that it started showing me above error during boot up.

Please help me with this.

Hello Again:

a work around is edit the fstab so as to not to check the partition at start-up..

Give this command for more info

man fstab

Quote from the same:

[QUOTE]
 The sixth field, (fs_passno), is used by the fsck(8) program to deter‐
       mine the order in which filesystem checks are done at reboot time. The
       root filesystem should be specified with a fs_passno of 1, and other
       filesystems should have a fs_passno of 2. Filesystems within a drive
       will be checked sequentially, but filesystems on different drives will
       be checked at the same time to utilize parallelism available in the
       hardware. If the sixth field is not present or zero, a value of zero
       is returned and fsck will assume that the filesystem does not need to
       be checked.
[QUOTE]

In short means the value under the <pass> column should be set to 0 to bypass fsck

To edit the fstab give the below command in a terminal:

sudo gedit /etc/fstab

and change the values under the <pass> column entry from 1 to 0

and save the file and you should be done

Hope it helps

Hi...

This helped...

This disabled the file system checks during bootup..

But why does it show

"There are differences between boot sector & its backups"??

Is there any issue with my HDD?
