Hide a partition

I use Windows 7 for 64 Bits. My partitions are dynamic.
I need to hide two of my partitions (D and E). There are some solutions for this here at WBB and in Google, but I need a procedure or app that hides the partitions even if my HDD is hooked to another PC as a slave disk. Is that possible?
Thanks
