Why does the disk drive light stay on (XPs)?
According to the XP-80 manual, this is normal behaviour. The light on the disk drive stays on constantly when the power is on and becomes brighter when the XP is reading or writing to the disk. The disk drive keeps spinning which speeds up access to the disk because the disk drive is always in a ready state. It is doubtful that this behaviour will wear out your disk drive, however I would recommend removing disks from the drive when you don’t need them, because the disks themselves will eventually wear out. (I also do this because it is quieter without a disk spinning). Warning: Don’t remove the disk while it is being read from or written to. The drive light is brighter when there is disk activity.
