Then use an intelligent automounter, that only mounts things you want it to and lets you make choices about the rest :) > Thanks for the explanation.

The partition table may be slightly faulty, hence the need for fdisk. Recreating the partition table with fdisk should fix that permanently. -- Neil Bothwick Those who live by the sword get shot by those who don't.
