My C drive is 28.6 GB of which 17.7 GB is free space. My S drive is a slave drive which I have partitioned into G partition (31.48 GB Logical) and I partition (7.813 MB Primary). http://img53.echo.cx/img53/2556/screenhunter0128zt.jpg 1. I plan on creating a secure zone in the G partition. Am I right in having it formatted as a Logical partition? 2. I had no choice really in formatting the I partition as a primary partition, other than leaving it unallocated. What is the purpose of this partition? Acronis tells me making the partition primary makes it bootable. What would it boot to (if this makes sense)? Why can't I format the whole drive as a single logical partition?
