166 Chapter 14—SCSI & External Disk Drives
D24—Owner’s Manual
Connecting the D24 to a Personal Computer
The D24 can be connected to a personal computer via SCSI. The personal computer
can then mount the internal MO disk drive and any connected external MO disk drives.
Since the D24 uses the DOS FAT16 filing system to manage files on disk, MO disks for-
matted on the D24 can be mounted by PC computers running a Windows operating
system, or Macintosh computers that can mount DOS formatted disks. The D24’s
internal MO disk drive appear on the computer’s desktop much like any other drive.
External hard disk drives can also be mounted by a personal computer, although this
only applies to disks that were initially formatted as DOS FAT16 volumes using a per-
sonal computer. See “Formatting External Disk Drives” on page 158 for more informa-
tion.
When the D24 is connected to a personal computer, the SCSI connection between the
D24 and internal MO disk drive must be disconnected temporarily. See “Accessing the
Internal MO Disk Drive” on page 168 for more information.
D24 sound files and some of the project settings files appear on the computer’s desktop
much like any other file. Since the D24 sound files use a proprietary Yamaha format,
you cannot play them using common audio playback software.
When a D24 disk is mounted by your computer, do not use any disk utilities on the disk,
such as defragmenting software. Doing so may damage the disk or stored data.
To connect the D24 to a personal computer, the computer must have a SCSI-1 or
SCSI-2 interface. Since each device on the SCSI bus must be assigned an exclusive ID,
you need to be extra careful that the SCSI IDs used by the D24 and any external disk
drives do not conflict with those used by the computer and any connected peripherals.
PC computers typically use ATA-type internal hard disk drives, which don’t require
SCSI IDs, reducing the risk of an ID conflict. Macintosh computers with built-in SCSI,
on the other hand, typically use SCSI ID 0 for their internal SCSI hard disk drive and
SCSI ID 3 for their internal SCSI CD-ROM drive.
Use the following SCSI ID table as a guide when connecting the D24 to a personal com-
puter. See also “Assigning SCSI IDs” on page 156 and “Setting the SCSI ID of the Inter-
nal MO Drive” on page 193.
To connect the D24 to a personal computer, you’ll need a good-quality SCSI cable. The
end that connects to the D24 must be fitted with a 50-pin, half-pitch SCSI connector
(pin type). The SCSI connector on the other end must match the SCSI port on your
computer. See the owner’s manuals supplied with your computer for more informa-
tion.
Note: Do not attempt to access the D24 MO disk drive or any connected external disk
drives while the D24 is in use. Doing so may seriously affect performance.
