■Error Messages
If an error related to the disk occurs, one of the following messages may appear. If this happens, check the possible
causes and solutions listed below. If all else fails, try a different disk. If this doesn’t clear up the problem, contact your
Yamaha dealer.
dEr Disk Error. An error occurred while writing to or reading from the disk.
Try the operation again; if the error occurs a second time the disk or drive may
be faulty. If the drive has been in use for some time the heads may be dirty. Clean
the heads with a commercially-available floppy disk head cleaner. If the error still
occurs with one disk and not others the disk should be considered faulty and should
be discarded. If the error occurs with all disks the drive may be faulty. Refer the
problem to your Yamaha dealer.
Pro Write Protected. You have attempted to format, write to, copy to, or delete data from a write-
protected disk. Use a disk that is not write protected (set the disk’s write-protect tab
to the write-enable position).
For Unformatted Disk. The loaded disk is not formatted for use with the PDP-400. After making sure
that the disk does not contain any important data (for another device, for example),
format the disk as described on page 38.
