I try to open it by using c drive and ejecting it butt it doesn't work

What are you trying to do? Eject C drive? C drive is normally your boot up drive, why are you "ejecting" it?

If it is your CD drive which won't open, then buy a new one. They are cheap enough. Just take your case off remove the power + ide cable and make note of where they plug in and then put the new drive in.

My dvd hardrive don't open ? Thaks

Your "C" drive doesn't eject.

You probably mean your "CD ROM"

Try to cheek the sysbol very well with drive that is working for because C it usually booting storage place why other drive we follow by D,E& F
