I want to check my partition for errors using Disk utility.
When I press the "Check Filesystem" button, it says that an error occurred ... device is busy. How can I ignore that error and carry on with the check?
I have Ubuntu 12.04 LTS.
The device/partition may be mounted or being used by some process. Also, please don't try to run a check on a mounted file-system; can result in severe data loss.
I'd suggest booting from a Live CD/USB (ensure that your drives are not mounted) and then trying to run ``fsck".
