I’m creating a Mac OS X USB boot drive, just in case

So I’ve decided to make a USB boot drive with lion just in case of my MacBook Pro HDD decides to die on me..

Fired up Disk Utility, created a Mac OS X partition on the thumbdrive  and restored the lion dmg (InstallESD.dmg) to the drive.

Ejecting USB drives takes two tries with CleanMyMac

Some time ago I found that when I tried to eject any external drives  from my Mac it always failed on the first try, but succeeded on the second.

This is very annoying, as I’m using alfred to speed up pretty much every command on my Mac. So basically I had to type “eje” (the start of the Eject command) two times instead of one..

It turned out that CleanMyMac checked the drives as they where being unmounted, thereby locking the drive. So I disabled these settings and voila, everything worked.
