[ltp] how to silence the hard drive
Mon, 06 Jul 2009 12:00:02 +0200
I recently found something that I would like to share with you. It
concerns the quest of silencing the HD.
One problem is obviously that the OS keeps writing things to the HD, and
there are a number of articles that discuss different ways to deal with
that, see, e.g., laptop-mode package, etc.
However, I was never really satisfied with the results, because my HD
never kept silent for more than 30s.
Now, i discovered the following possible entries for /etc/fstab:
tmpfs /var/log tmpfs defaults,noatime,mode=1777 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
this generates a ram-disk for each mounted tmpfs, i.e., all temporary
stuff goes into the laptop's memory so that the HD is not woken up anymore.
to enfore firefox to use /tmp, one can do the following:
*Move Firefox cache to RAM disk*
/This might not be useful if you're on a very slow modem connection and
restarts your computer very often./
* Open Firefox.
* Type *about:config* in the search bar.
* Right click on any row.
* Select *New > String* from the popup menu.
* Add *browser.cache.disk.parent_directory* and press enter.
* Close Firefox.
