I've tried repartitioning the whole drive and it wont, it just keeps giving me an "input/output error" message. i've tried erasing also. i've tried using terminal to do it by hand also. no luck. i do have some spare IDE's around but this box dont have IDE ports only SATA.

I read somewhere that there was an issue within diskutil that was not working properly. but i dont have any other OS X disc to try with. thats the main reason i downloaded this new 10.5.2. EFI. hoping if this one didnt intall completely then i would just use it to partition the drive then simply use the first disc to do the intall on the newly/correctly formated drive.

btw. im not trying to dual boot at this point just want to try out Leopard. seeing as how i've always only used Windows.
