How to get back space on hard drive

[hiddenfury]

I was trying to install snow leopard onto my macbook pro 13 in which runs os lion by partitioning my hard drive. I accidentally made the snow leopard partition too big (about 140 gb) so I deleted it and then I tried to increase my original partition back to its original size. However, now it says I used 309 Gb out of 320 Gb of my hard drive. How can I repair this? Thanks

Lion puts a recovery partition on the HDD, and it hides it.

Hold down you 'option/alt' while booting up and the lion record will show.
