Comment 1 for bug 245022

Thank you for taking the time to report this bug and make Ubuntu better. We need to try and determine what process is using your hard disk. To do this, could you please try running 'iotop' from the terminal and report back which processes are using the most disk I/O? Iotop is not installed by default, and is not available in the normal Ubuntu software channels. However, it is available from Tormod Volden's PPA, which can be accessed here: https://launchpad.net/~tormodvolden/+archive.

Please note that high disk I/O can be a symptom of many different problems. Whilst there might be a few people exhibiting high disk I/O, there could be many different causes for this. This means that your problem may be unrelated to the problems seen by (or discussed by) other people with these symptoms. Your problem is not 'critical', as there is no evidence to suggest that it is affecting a large number of users.

You could also try disabling Tracker (if enabled) to see if your problem goes away.

Thank you
