its only 40 gb i am trying to format it from : my computer and computer management neither working and i cannot acces until i format it what to do please help

I get that you're trying to format a drive but beyond that I can't cypher what you're trying to say.
Try to be a little more specific with less shorthand.

hi tarekk, if you're trying to format a hard drive make sure that's its detected by CMOS. If it is detected by CMOS by right Computer Management should be able to detect it, if not then it could be a faulty HDD.
