Alright. So my computer got screwed up about 2 weeks ago and i have gotten all the files i want to keep on my secondary drive (D:\) I have 2 drives. H: which is my primary, and D: which is my secondary. H has Windows XP Home on it. I created a bootdisk by right clicking my A drive in My Computer. Clicking "format" and checking the "copy system files" box. When i boot up with the A drive, it starts up in dos. I read a tutorial somewhere that said to format my drive i do this, CD H: FORMAT H: \s \v And it should be formated. Now heres my problem: I cannot change my directory to H:. It says "Invalid Drive Specification". I have tried "CD H" "CD H:" "CD H:\" But nothing works. The only thing that DOES work is "CD A:" How do i fix this and am i re-formatting correctly.. THANKS!
