Well, yea, kinda.  I was just wondering what can your wife's account see in 
the /dev directory?  It could be that she can't see anything.  Another thing 
I"m wondering is if there is a difference in groups, etc. in your wife's 
account and yours.  /dev should have permissions:  766.
However, you may want to back off those permissions for /dev/sda1 to 660 
because /dev/sda1 is not a directory, so executable is not needed.  (Also 
make sure root is the owner of the devices and disk is the group.)
