I Just used the EASEUS Partition Master, the tool recommended by Ramchu at http://www.partition-tool.com/personal.htm
. It worked perfectly. I was able to shrink the Vista partition and then load PCLOS 2010 in the blank portion of the hard disk. As far as I am concerned, this question is solved thanks to Ramchu.
Before running EASEUS Partition Master I defragmented the hard drive and I ran chkdsk c: /f from the terminal. I have been told that chkdsk must be run from the command line, not the GUI. In order to run chkdsk from the command line you must right click on the terminal in Vista and select administrator. Once you type in chkdsk c: /f and hit enter you will be asked if you want run chkdsk upon reboot. Type y, hit enter, then restart your computer. Chkdsk will automatically run before the reboot and fix disk errors. The "/f" command is a command to fix errors. My understanding is that If all you want to do is see the errors, you can simply run chkdsk from the command line and hit enter and it will list the disk errors.
