I have a netbook , Asus eepc 1215N, with 2 gb ram. It has become very slow ,running win 7. I'd like to install a Linux distro so i hopefully gain some speed back (use it mostly now for browsing ). My system partition has TC WDE on it , i just started the option:"permanently decrypt system drive/partition". It has 7 hrs to go ....... Question: can i just format the drive ( with a disk utility run from usb or external cd drive )? there is no data to be kept.
