How do I fsck my boot drive?

[ICMike]

What is the procedure for checking your boot drive? Should I boot to the recovery boot option then go to root?

fsck /dev/sda1

I'm assuming I should check all partitions sda1, sda2 and sda5.

You can always fsck a drive by booting from a live CD, but there are ways of getting it done at a regular boot.

The boot drive will be fsck'd automatically every so often (possibly every 20 boots?), and you can change this frequency with tune2fs.

Also you can force this in various ways - although I haven't done these recently nor confirmed they work on Ubuntu systems:

sudo touch /forcefsck

and reboot as normal

or

sudo shutdown -rF now

As to which partitions you should check, yes, all partitions occasionally (except a swap partition - no point in fsck there); it depends if you have issues at the moment.
