ITunes filled up my HDD and I can't clear it!

I'm stumped. I installed iTunes onto my main HDD, main partition, and was going to use my music off my external HDD. Problem is, when iTunes started compiling a database, it told me I ran out of hard drive space. Somehow I lost 20Gb (at least) of space in this time, and now I'm running with only 850Mb of free space on my main partition. I uninstalled iTunes, thinking it would erase that data... but it didn't. I've used CCleaner, cleaned my registry and installation as well as doing a disk cleanup with it, and still, those files are somewhere hogging all my HDD space. What on earth do I do? I'm using XP Pro SP3 and my HDD is a Samsung Spinpoint-P 250Gb SATA with two partitions, ~125Gb each. Please help, this is urgent!

 

hmm my suggestion explore ur HDD with some of the software from any of these (http://www.majorgeeks.com/download.php?id=8&sort=7) and then see where the main problem is i had a similar problem with jkdefrag and had to delete 6 gigs of senceless data with the poblem i didnt use partitions but it should probably be about the same deal

 

Am I supposed to be searching for specific files or what? There's a lot of programs on here, and I'm not quite sure which one I'm supposed to be getting, or at least what the purpose of said program is to be.

 

I USEd that JkDefrag and that didn't affect it at all. Should I try something like Total Commander?

 

Okay, I tried using AMUST disk cleaner to find what was taking up so much space... no dice. It's stright-up invisible. Someone's gotta know winXP well enough to help me out here...!

 

Tried Windows Disk Cleaner?

Maybe Windirstat might help id what is taking up space.

 

ya the files are hard to find short of scaning whole drive then viewing only the must space taken idk what is wrong with your drive short of seeing it
