Clear temporary Windows Update installers

If you have problem to update Windows, e.g. it gives you 80072EFE error, it may be worthwhile to clear the Update Installers in your system and restart again. The instructions can be found at:

Especially method 10 which tell you how to empty the software distribution folder.

After you clear the "cached" installers, you may want to restart you system before re-try the update services.

VirtualBox USB and Ubuntu

I finally manage to get the USB working inside VirtualBox. I followed the instructions from this site https://help.ubuntu.com/community/VirtualBox/USB, restarted my machine, and like magics, my USB works inside my guest system now!

Ubuntu and NTFS

It seems that by default Ubuntu does not allow you to format drives with NTFS system. If you want to have more advanced options, you need to install the package ntfsprogs, i.e.

sudo aptitude install ntfsprogs

After the installation, you can format disks with NTFS system and check their "health"
