Partition magic expirence??

[tpunx99GSX]

Does anyone have expirence using Partition magic, today i used it and created a partition that i could backup some files so i could reformat my computer and when i restarted the computer to finish the setup of the partition the computer froze at around 10% of being complete, so i turned the computer off and when it started to come back up winblows xp would keep restarting my computer when the startup screen would come on, so im thinking oh great my xp is fucked. so i put in the xp cd to reinstall it or to make sure the partition is still there, and sure enough its not seeing my original partition, and my 120 gb hard drive is only showing 35 gb of space which is the space that i had allocated to the new partition. Does anyone know how to bring that partition back and maybe get some of the files back that were on it namely one file that was a .rar or .zip file that had all my backed up items such as pictures and movies?????
I really need this back so any help would be greatly appreciated.
