every time i start up my computer, it goes fine, takes a little less than a minute, and everythings fine, then i get to the login section and it says "There is no disk in the drive, please insert a disk into drive /Device/Harddisk1/DR3." Then it takes a awhile to get to the desktop, then everything takes forever to do. Im pretty sure that its the hard drive, and it crashed, but i dont know. and yes it is in there and all connected. i have an emachines t6524. please tell me how i can fix it...
