I have quite a startling problem, i use a 32 bit Vista OS, and i have a bunch of games i play on it. I uninstalled a few, they were all above 6 GB, so i though id defrag my harddisk. Well i tried to defrag with vista but the program never opens ( the default one).... then i tried Pc Tools Disk Suite, and everything was going smoothly, then my laptop just went off and i forgot that it was on low battery... now the startling bit, wheni checked the amount of space i have on my hard drive i found out that i had actually 10 GB less than how much i had before i started the defrag. I started with 43 GB and now i have 33GB...i thought defrag was supposed to clear space.. and i think the sudden shut down of the computer messed it up. PLEASE HELP!!!
