hard drive is in read only

[atlrocks07]

today i installed windows server 2003 on 1 of my 3 hard drives. i have 2 sata and 1 ide...i had nt had a chance everything from my ide to sata... so i installed windows server 2003 just to mess around for a little bit to learn some of it..until i had time to restall xp on the new sata....so my whole problem is that i put my music and video hard drive into a read only..idk what i did but i can create new files on that hard drive and i can read them but cant read the ones that are on there..

and its read-only on xp and window server 2003

thanks
