[Tfug] MBR problems

[R351574NC3]

Well, disk utility should have been provided by your HD manufacturer. Of 
course, linux gazette recommends that the best thing to do is dd 
if=/dev/zero of=/dev/hda (or whatever you are using). You want to make 
sure you wipe out the whole disk. Getting rid of the MBR naturally 
cleans up the partition information, but the partitions are still there. 
The idea is to clean all partitions.
