When I first got my computer I was able to store information, photos etc. on a 650 meg disk. Now when I try to store info on that same disk I get the message " This file is on a network drive with create but no modify privileges. Please ask the administrator of this network to change this condition.", and I am unable to store the info on the disk. I am not hooked up to any network that I know of. Can anyone help me get my computer back to normal? Step by step instructions please, as I don't know much about computers. Thank You.
