40gb of hard drive space disappeared due to boot camp

I recently had a second partition on my MacBook which was a fat32 that had windows 7 on it. I decided I wanted to remove it and did so through the boot camp assistant. After deleting windows 7, I went back into boot camp to merge partitions and after that operation completed, the 32gb of space that was used for the partition was gone. I tried using the disk utility to find second partition but can't, it only recognizes the partition that mac osx is on and says it is 120gb capacity when hard drive is 150 gb. I would like to format the entire hard drive and have it as one partition again, does anyone know how I can do this?

Keep in mind things I have tried to find hidden 30gb's of space. I already erased hard drive through the disk utility. I tried to use all features of boot camp. My computer can't find missing space and I am super frustrated. I have snow leopard and my computer is a white MacBook from 2008 with intel core duo chip.
 
I would double check the figures again to see exactly the sizes
Your 150 GB drive will never show 150 GB available

Your answer *might* be the HDD discrepancy listed on the Guide here at MR: Hard Drive Size Discrepancy

Hard Drive Size Discrepancy

Why does my new 500 GB hard drive report it only has 465 GB? Have I been ripped off?

No, you haven't been ripped off. 500 GB = 465 GB, strange as it seems.

The reason is that computers count a "kilo" something as 1024 (binary 2^10) while the rest of the world count a "kilo" as 1000 (decimal 10^3). A 'mega' in computer binary system is 1024 x 1024 = 1,048,576 (rather than decimal 1,000,000), and a 'giga' is 1024 x 1024 x 1024 = 1,073,741,824 rather than decimal 1,000,000,000

This creates a discrepancy of approximately 7% between the number of GB the computer reports, and what is advertised as the drive's capacity in GB. It is important to note that there is no difference in the number of actual bytes of storage - it is only a difference in reporting when the binary 'giga' terminology is used.

A 500 GB hard drive has about 500,000,000,000 bytes (it is never exact, commonly a drive is designed to have more bytes, to allow for a certain number of defective sectors to be mapped out). When counted on the computer, 500 Gb (decimal) = 500 billion bytes = 465.66 GB (binary).

Some propose using a different term, gibibyte (GiB) for the binary figure, however that is unlikely to catch on in the marketplace.

As seen here, my 1 TB HDD shows up as such (and yes I am running snow leopard)
