Test your hard drive with this utility. Disk Test can write to all free space. Covers old file data. Verifies operation of all disk space. This program will create a file named ~temp.tmp and start writing to it, and will continue until all of your free space has been overwritten. It tests all those upper locations on your HD that you probably have never written to. When you have a 200GB drive and you have 140GB used, that is not the time to find out you can not write more than 148GB. Test it out with this program.
This tool will erase the temp file and release all that clean memory that now has nothing but billions of the character U.
