I hope this is the most appropriate forum to post this
question in.....?

I have just divided my hard drive using Partition
Magic into two partitions C and E and have installed
an installation of XP on both. My thinking is that the
version installed on partition E will be used for
testing software, visiting dodgy web sites etc and
will frequently be re-installed from scratch.

My problem is that when I boot from the C drive
installation I can still see the E drive and
vice-versa. I would like to totally isolate the two
partions such that any viruses/malware etc picked up
on the 'scratch' installation on E cannot be passed
across to the C drive installation.

I think I can hide the partitions from each other
using Partition Magic and the Boot Manager, but will
this completely isolate the partitions from each
other. Can I achieve the isolation by setting the
sharing permissions from Windows in someway?

Hope this makes sense? Any help appreciated
