The solution: manually set the number of reserved filesystem blocks to zero:

sudo tune2fs -r 0 /dev/sdb2

Replace /dev/sdb2 with your partition.

My 2.5″ Enclosure has no switch on/off, so … to turn it off I have to plug and unplug the usb cable, but … there’s a better way

All I need to do is to install sg3-utils, and use two simple commands to turn off/on my external usb drive.

apt-get install sg3-utils

and to turn it off/on

sg_start /dev/sdb –stop
sg_start /dev/sdb –start

that’s all!

Let’s assume your original location of mysql is at /media/disk/…
Your new location of mysql is at /
You just need to synchronize two directories /etc/mysql and /var/lib/mysql/. Remember to stop mysql before doing this, and start it after synchronisation.

/etc/init.d/mysql stop
rsync -rav /media/disk/var/lib/mysql/* /var/lib/mysql/
rsync -rav /etc/mysql/* /etc/mysql/
/etc/init.d/mysql start

that’s all!

After some Googling, I found something that solved my problem.

The solution on How to Force Enable Incompatible Extensions In Firefox 3 is very simple:

• Type about:config into Firefox’s address bar
• Right-click anywhere. Choose New>Boolean. Make the name of your new config value extensions.checkCompatibility and set it to false.
• Make another new boolean pair called extensions.checkUpdateSecurity and set the value to false
• Restart Firefox.
• Now, you can activate your incompatible extension, and check if it works with Firefox 3

That’s all
