There is any easier way of dealing with wins.dat, turn off nmbd. This 
will stop it being created in the first place, but you will not have 
network browsing.

you should probably be aware that wins.dat is not a log file and I don't 
think that it is your problem anyway. If you do a google search, you 
will find lots of results about usb drives not wanting to hibernate.
