Windows 7: Want my partitions to display as 50GB (C:\) and 60GB (D:\)

Want my partitions to display as 50GB (C:\) and 60GB (D:\)

I have 120GB SSD and partitioned it into two C:\System Files (1024MB x 50) and D:\Documents And Settings (1024MB x 60) yet when I navigate to My Computer it shows up as 49.9GB & 59.9GB? I've since encrypted the drives using bitlocker so will resizing the drives inter and how do I get them to display precisely 50GB & 60GB or maybe their is a way to toggle on/off the available storage capacity?

Use partition wizard, you can get them perfect :)

How many actual GB are in a 120 GB ssd, my 128 GB OCZ is actually 119 in windows. My 180 GB Intel is actually 167 GB in windows etc.

Disk management will tell you the actual size, in the small box on the left side.

It's not illogical to get such small differences. There is some minimal overhead for maintaining the file system (such as boot sector, reserved areas, mft, etc) that are not counted towards the total amount of space really available. Also consider that the tool displaying that number does some rounding that affect the final result, and depending how precise it is with the maths it may show 59.9 or simply round it up to 60 at some point for simplicity. Most likely this is the actual cause of those minuscule variations.

Both are really the very same number (except for minor rounding differences of course), but there is a subtle difference in the measurement units used in each case. Hard disk vendors typically use gigabytes to advertise disk capacities, while Windows has historically used gibibytes to report storage amounts, even though it shows KB/MB/GB everywhere, which is a bug.
Doing the maths you can get the same numbers:
128 GB * 1000 * 1000 * 1000 = 128000000000 bytes / 1024 / 1024 / 1024 = 119.20928955078125 GiB

Learn something new every day. I never heard of "gigibyte" until I read this thread.

Edit: Just wondering. If MegaByte is only 10 to the third power bytes, then where is MegiByte for 1024 to the third? Seems like some stuff is going metric on me. :)
