Hard drive light is constantly on. What's using it? [closed]

The HDD light is lit solid all day and the system has slowed significantly.

Running i7 with 15.3Gb RAM on 10.04

Read though many threads online and checked the I/O which seems to be negligible and only writing to the journal - jbd2/sda1-8

The fsdsk shows that sda1 is healthy and in good form.

looking at glances things look good:

Blender is running. but its not doing anything.. just sitting there.. even if I close Blender the HDD light still stays on...

Trying to figure out what's slowing down the system...


Download iotop and run it to see which process is accessing filesystem :

  • sudo apt-get install iotop
  • sudo iotop -P

So i'm not sure what was happening to my machine but it only started giving problems after one of the routine ubuntu updates. Then stuff started to fail. clicking the restart button just brought up a small blank window and programs started failing... After a forced shutting down I was stuck at boot up and wasn't able to get past

BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands

(initramfs)

After much digging I found this thread which got me back up and running:

Can not boot! initramfs error!

The steps that worked for me were:

The following step is for removing the i-node

In the terminal I typed

sudo debugfs -w /dev/sda1 debugfs 1.41.11 (14-Mar-2010) debugfs: clri <8> debugfs: quit After that restart the system and again boot into the live cd

In the terminal type

sudo fsck -yv /dev/sda1 It will work.....definitely

After logging into the desktop in the terminal type the following commands

sudo apt-get update sudo apt-get autoclean sudo apt-get check

Hope it helps someone else...
