I have a multi boot setup with windows 8 and ubuntu 13.04 and i'd like ubuntu to ignore completly the disks tha are related with windows.
I know that i could write some script to delete devices by
echo 1 > /sys/block/sdX/delete
for every disk tha i want ubuntu not to show up but it would be better not to add these disks in the first place.

Also tried to ignore from udev by placing a rules file in /etc/udev/rules.d/ with something like:
but with no luck.

Anyone has any idea how to prevent ubuntu from using disks?
