When I try to save info on my 3.5 disk I get the error message A:/ is not accesible. No ID mark was foung on the floppy disk. I am operating win2k. I have tried different disks. The drive worked at some point. I cant format a disk. WHEN I TRY THE DRIVE W/O A DISK IT SAYS PLEASE ENTER A DISK. The light comes on only when I try to access the drive. I have opened the box to add a dvd/cd burner I have installed some programs by downloading but not by disk. i dont know what a bios is but i dont think i messed with it. HELP PLEASEWhen I retart the computer with the disk in the drive it does not ask me to remove it. I tried the floppy drive in safe mode same thing. how do change the bios on startup?? I couldnt find it.
