When partition a disk, it is not possible to divide disk's geometry (I think the geometry - CHS) exactly evenly. so there is always a little bit left over at the end (8mb sounds right) because the math has to go to the nearest round figure. The extra just falls off at the end, you don't see it (or you can format it as a logical partition if you want - like Scott has done here - and it will show up on your partition table). But usual you don't bother about it and it doesn't show on your screen except in Disk Management, where it's visible at end of the table as empty unformatted space.
For example when I partition a 25OGB disk, I would allocate say 40GB for system drive and say 60GB for storage, so I'm off for a start. There is 150GB remaining which I get round to when I have decided some use for it. The 150 GB only shows in Disk Management where I go when I need to re-evaluate my partition table.
Otherwise to all extents and purposes, 100GB is enough for most people to get by on for time being, and thats all that shows on drive settings in My Computer. Add on another partiton when needed - say, when the movie or music collection starts to grow too big for existing partitions.
Alternatively you can format one 250GB partition, or, since many people like to keep system drive separate, 50GB for C:\ and the remainder into storage partitions according to what storage cabinets you think you need.
In your case Scott, you've partitioned and formatted that little extra bit (8mb) that can't make the math when the allocations were worked out, so you are seeing it in your drive set up My Computer. If you delete it so that its empty space, you should not see it in My Computer (best thing to do - just lob it off your work space and don't worry about, its not much use anyway). If you do feel need to access your total space, then you can go to Disk Management and see the whole table.
