Open /etc/fstab in a root text editor:
gksudo gedit /etc/fstab
You'll see a line beginning with /dev/hda, I'm hoping. If not, it might have the following sort of thing:
# /dev/hda
UUID= <lots of letters and numbers with some dashes>
At the end of the /dev/hda line or the UUID= line, you'll see a zero, then a tabbed space, then a one. Change the one to a zero; we want both of them to be zeroes.
Save changes, and close the text editor. This should disable automatic filesystem checks. Very useful if you've got a 500 gigabyte hard disk
Be sure to manually check the drive every so often for safety!
Can any experts here help me, after I installed Ubuntu 8.04 LTS for a few days, it automatically scans for hard disk error stuffs everytime when I boot up. This is annoying, but how should I turn it off?
Technical details: Windows XP and Ubuntu Dual- boot machine, XP on /dev/hdb1 (NTFS), Ubuntu on /dev/hda (Ext3) and Personal Music / Document Stuffs on /dev/hdb5 (Ext3, despite Windows XP shows Ext2, using the Ext2IFS program.)
