I appreciate your responses, and have heard of the dynamic-disk thingness before, but ...
The problem is not what to do with the 7.84 mb space, but rather determining where it came from.
Around 06-01-2010 I installed Windows 7 and was amazed to find it had written the first partition of 100mb (BCD, bitlocker, etc). It cost lots of time to find out what it was and consolidate it into the functional Windows 7 partition. Acute Heartburn!
By 08-11 I was certain that I wouldn't place primary reliance on Windows 7, so I spent lots of time learning about Windows 7/XP multi-boot, then installed XP as the 2nd partition. It did not create the 7.84 mb space.
The thing is, I need total control of what is stored on my HD's in order to specify and execute my backup strategy. I suppose I'm kinda "old school" in that it flat-out boggles my poor brain that *any* software product would write some unknown and unspecified (to the user) storage entity to a HD. Even worse that it would hide it from common program facilities like "Disk Management".
So, I'm just after control. Where did it come from? How can I prevent it from re-appearing?
