Apple OSX can read form a lot of disk-formats, but can not write to them.
First problem, windows NTFS.
Tuxera

Email
If you have more than 1 email address (who hasn't), you probably have the problem that when sending an email the wrong email account is selected in Apple mail.
On the internet there are some suggestions how to change this in older version of OSX, but the following method will work for OSX Lion 10.8.2.
Start mail
In this example the HF One needs to be the first mailbox.
Click the command key (⌘) and click and hold the Left-Mouse on the HF One icon or HF One-text and drag it above the iCloud
Release mouse and command key when the correct position is reached.
This should endup with HF One above iCloud.
That's it.
