Chapter 17 Using Hard Drives

This chapter explains basic concepts, internal structure, and
basic operation regarding the use of hard drives with the VS-
1680. Read this chapter thoroughly to gain a better
understanding of how the VS-1680 operates.
General Information
Regarding Hard Drives

Drive Partitioning

The VS-1680 saves all data, such as performance data, mixer
settings, system data, etc., on the hard drive. It cannot
operate without either having an internal drive or being
connected to an external drive via the SCSI connector.
Furthermore, the hard drive or external drive used by the
VS-1680 cannot be used by another device. The VS-1680 is
able to address 500MB, 1000MB, or 2000MB sections of drive
space at once. If you use a drive with a capacity that is larger
than this, you will need to divide it into appropriately sized
sections. Each of these sections is referred to as a "partition."
You can create up to eight partitions per drive. With larger
drives, we recommend you create 2000MB partitions.
Ex. 1: When the drive is 810 MB, and the
partition size is 1000 MB.

Each partition on the VS-1680's drive is treated as an
independent drive, and is given its own partition number (0-
7). When a single hard drive has multiple partitions, you can
specify which partition of which drive will be used ("Drive
Select," p. 222). The drive partition currently used is referred
to as the "current drive."
* If you wish to use removable disks or song data on both the
VS-1680 and the VS-880, there will be limitations as to what
you can do. This is a result of factors such as differing
partition sizes and the available number of tracks. For more
detailed information, refer to Chapter 20, starting on p. 239.
* The VS-1680 uses Roland HDP88 series hard drives, although
it is possible to use other drives. For simultaneous recording or
playback on the maximum number of tracks, getting more out
of the available hard drive space, and in order to get the fullest
performance in general from the VS-1680, we recommend
using the HDP88 series hard drive. In some countries, such as
the United States, the VS-1680 is shipped with an HDP88
series hard drive already installed.
