I have just purchased and installed TI 10 (and got update 4942). I have made a bootable CD. When I tried a full backup, I decided to put the tib file on my E: drive (I have C and D drives of 40 gb each and an E drive of 80gb which I use mainly for storing mp3 files and photographs). I thought it would be better to put the tib file on a CD/DVD but Nero would not accept it. I would also like to know if I should set up a secure zone. Sorry if this is very basic but I am totally new to this! Thanks.
