Constant Accessed to HD after upgrade.

[Ifaistos]

Hello everyone

I have experienced since the upgrade to 11.10 that my HD access is almost constant.
In the beginning I thought that the memory was loaded and had to access the swap file. However when I closed a couple of programs and memory was freed, it still did the same.

I see that my HD access led is being continuously (almost constantly) lit.
I am already searching for a couple of Geil PC3200 chips to increase my memory to 4GB. I have installed the 64bit version so I will be able to access it all.

However I think that the constant accessing to the HD should be caused by smt else and not memory inadequacy. I think that 11.10 is much more demanding on my rig, and I have experienced significant decrease in the performance of my PC.

I will test it again when I find the memory and upgrade it to 4GB. However I would like to explore the possibility that smt else is responsible for the deterioration of performance. Any ideas?

I am attaching one picture. The orange part is the HD access. I can't understand why Ubuntu keeps accessing my HD. It did not do that in 11.04.

Thanks everyone in advance...

I was thinking the same as you ..... memory .....

That would cause the disk usage - but you seem to rule that out ....

The things that I might consider doing is checking HTOP .... to see what activities are
taking place at the time .....

Hello and thank you for your answer.
Could you please be more specific?

What is HTOP, and how do I use it?

Thanks

Htop is an interactive process viewer for Linux. It is a text-mode application (for console or X terminals).

sudo apt-get install htop

Comparison between htop and top

• In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines.
• In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
• 'htop' starts faster ('top' seems to collect data for a while before displaying anything).
• In 'htop' you don't need to type the process number to kill a process, in 'top' you do.
• In 'htop' you don't need to type the process number or the priority value to renice a process, in 'top' you do.
• 'htop' supports mouse operation, 'top' doesn't
• 'top' is older, hence, more used and tested.

To use it, type it from a Terminal :

htop

I have installed htop and it runs just fine.
It looks like a text version of the System Monitor.

Is there something specific I should be looking for in order to find out which program(s) is constantly accessing my HD?

I think I misunderstood the question at first, sorry. If you are trying to see which process reads/writes to your disk, you'll need 'iotop'.

to install:

sudo apt-get install iotop

to use:

sudo iotop

It ressemble top and htop, but only for IOs activity.

Hope this helps

I installed Iotop.

It seems that there is only one thing constantly accessing my HD's.
Picture attached.

Can anyone understand what this is, and how do I stop it?
