[SOLVED] HDD light is on most of the time

In my AAO D260, the HDD led is turned on most of the time, even when the netbook is just turned on and not being used for a while. I don't know if that's something related to the filesystem or a program is constantly using it. If you need to know, these are the lines I have in fstab:

UUID=4b07196b-6704-4dc6-88ce-c343b8af9057 swap swap defaults,noatime 0 0
UUID=b0984a44-3276-4aed-807d-83613b2c05bf / ext4 defaults 0 1
UUID=dadf5fc0-28d4-4c2c-9357-0c63955f5a49 /home ext4 defaults,noatime 0 1
tmpfs /tmp tmpfs defaults,noatime,nodev,nosuid,mode=1777 0 0

and these are the programs running right now:

Does that light necessary mean that the HDD is being used? I'm worried bacause of disk degradation.

Thanks!

Re: [SOLVED] HDD light is on most of the time

Try to measure disk activity (write). A good human readable process-specific tool is iotop.

Just tried iotop and there seem to be no activity on the disk although the light is on. That must be some kind of kernel issue.

Thanks anyway!
