Formatting and booting from cd problems.

I'm trying to reformat my D(57gigs) drive partition and not harm my C(19gigs) drive, but everytime i use a awin98 start up floppy to get to some command prompts I try to put in Format D: but it says "Format not supported by D:, Format Terminated" but C drive can be formatted. I can't get to my Bios settings to have my cd rom to be first to boot but i went to set up and changed boot order but still cd rom wont boot first it will just pass on to the A drive. SO now I'm getting desperate and frustrated I asked some people not on here but friends they said not to format cuz it will kill my computer but theres a grip of adware things on here from trying to download a Keygen activator thing for PhotoshopCs2. if someone can help me get my D partition formatted I'd be grateful and on top of that from getting a blaster type virus or something from downloading mmorpgs my computer's internet went out so i did a system restore many times and it would freeze and not do anything so i would stop them and restart the computer and do it over. I had about 47-50 gigs now im reduced to 7 gigs of space and its a 80 gig hard drive so i dunno if space is stored or not or something is killing my space. . is there a way that i can increase the size and get rid of whatever took up the space if so that would help me out instead of having to reformat my drive.

 

its windows Xp i just want to wipe the D drive i cant fully remove the virus or whatever because i dotn have enough money to buy a proper anti virus program.

 

Is the D drive in NTFS file system? Being stubborn?
