was my mac hacked?

[angelwatt]

this also happened to me, which prompted me to look for answers, my hd was renamed from mac hd to numbers and letters also some files where moved around and renamed, does anybody know what could cause this? I'm gonna take human error out of the equation ,we my wife and I are both
working people and have no kids messing with our computer, we just want to make sure someone isn't trying to get personal information.

Can you provide more info. What was the HD renamed to? What other files were effect and where are they on your system? What type of settings do you have setup, like for Sharing for instance. Do you have any network services active like VNC or VPN? Like I said, need the info.
