(When I look at the 160 GB drive with fdisk, I see a size > that's a certain number of sectors (?) xxxxxxxxxx+ with a plus sign at the > end. ) They do not have to be exactly the same size. The size of the raid1 array will be slightly less than (to allow for metadata) the size of the smallest drive. So, partitions the 160GB drive as a single 160GB partition, and partition the 200GB drive as a 160GB and a 40GB, but don't be stressed about getting the sizes precise. Then raid1 the two 160GB partitions together, and you get a bunus 40GB non-RAID partition to play with.
