Must be OK then. I am sure both ways will do the job..
Did find this tho click here text taken from link..
If you find you run the defragmenter and it hangs like D.S.'s system, be sure that your anti-virus program and other programs are turned off during the defragmentation process
Some programs, like anti-virus programs, make regular hard drive accesses. This interrupts the defragmentation process. If this happens too often, the system will give up. It's kind of like when someone is doing math in their head and you start yelling out random numbers at them. Eventually they'll get distracted and have to start over. If you do that enough times they'll give up and punched you in the nose. Good thing computers don't do that.
Just a cautious warning to anyone who are thinking of trying IObit SmartDefrag 2.01,it is in BETA and possibly cause one or two problems.Though im sure it will run fine for most it pays to be aware of it being in BETA.Afterall,this is your harddrive your playing with.
Apologies if sounding over the top,but if you play with BETA products...be aware of the risks !
