I just did a W7 install on a 1.5 TB drive with 2 partitions. The first is about 300 GB and contains W7, the second around 1,200 GB has the 100 Mb reserved partition. I want to be able to do a full backup of the OS using software like Acronis. So now Acronis wants to back up the C and D drive which contains the 100 MB. I'd like to put other "stuff" on the D drive and not need to back it up in order recover my system if needed. So my thought is to use W7 to shrink the D drive down to 1 GB or so and then partition the remaining space as an E drive for my "stuff". That way I can use Acronis to recover my system without it needing to back up all my other "stuff". Make sense. Seems like it's easier then trying to move the 100 MB and all it does is use up a drive letter.
