Hard Drive Acts Full

[Arron_22]

My 1TB hard drive has 431 GB used but says only 46GB left in space. I've tried everything to see whats taking up space. Virus scans come up clean. Please Help me!

What brand is it? Are you sure it isn't just a 500 Gb?

Go into disk management and make sure that the entire disk is formatted as one partition.

Welcome to the community, Arron_22!

I'd follow @Mattios advice and check Disk Management on your computer! Check the partitions and file system of that 1 TB HDD. I'd also make sure there is no unallocated space on it. Here's a link that explains how to get there: http://pcsupport.about.com/od/windows7/ht/disk-management-windows-7.htm
I'd also check your HDD manufacturer's website for a diagnostic tool to test the health and SMART status of the HDD.
If it's your system/booting HDD, I'd run Disk Cleanup as well: http://windows.microsoft.com/en-us/windows/delete-files-using-disk-cleanup#delete-files-using-disk-cleanup=windows-7

Hope this helps. Keep us posted!
