When you are posting a computer problem or potential computer problem you need to do a few things for us. 1-What brand and model of computer is it. 2-What operating system do you have and is it up to date. 3-What type of interface are you using and is it Firewire or USB. 4-How much ram do you have, 5-Do you have an external hard drive (usb or firewire) or a secondary internal hard drive. 6-Have you tried tweaking the operating system from any of the many posted lists. I may modify this list as occurs to me from answering questions in the forum(s). The Jack Attack!
