When I try to read the boot utilities disk in the FDD I get a message "disk offline". The access light does light up but I cannot hear any noise coming from the drive...
Either diskette or drive.
(1) try this diskette on PC with dcopy (btw, do you have its image?)
(2) try other diskettes in MSX
No noise = heads are not moving, drive can not/does not read track 0 (for some reason)
looks like the drive is broken.
There are different types of drives.
If it is one with a belt, replace it.
If it is one without belt, replace the drive.
