I don't know what I did, but I couldn't figure it out..

For a couple of days now, the G drive's label is using a bold font.
Usually, it's the letter that gets assigned to a removable drive.
It is bold for any USB drive I mount.
A HD with two partitions, has the one bold and the other not.
If I assign the same drive in a different letter, it is displayed normally.
It's the only letter that gets this behavior.

Is there a setting somewhere that I absent-minded set?
Is there a way to do this in purpose?
