DD8
plus Version 2.20 - September 1998
NOTES REGARDING THE USE OF MULTIPLE DISK DRIVES
The DD8 can have several disk drives on line at any one time and these may be a combination
of fixed hard disk drives or removable disk drives. The DD8 can play audio from any disk at any
time. Furthermore, a single project can access audio from any disks that are on-line. For ex-
ample, a project could be playing music from one disk, sound effects from another, foley from
another and dialogue from another. However, please note that when using removable disks (i.e.
MO disks), it is vital that the correct disks accompany the project if it is transferred elsewhere. In
the above example, if the disk containing the foley did not accompany the project when it is
transferred to the mix down room, the foley would not play. However, you will note that the rest of
the project will play correctly - you simply won’t hear the foley cues until that disk is put on-line.
Note that there is no restriction into which drive a removable disk can be placed. If, on System A,
the music disk was on Drive ID#0, the sound effects on Drive ID#1, the foley on Drive ID#2 and
the dialogue on Drive ID#3, they do not necessarily have to be in that order when transferred to
another System B (i.e. you could swap all the disks around and everything would still play per-
fectly). This allows a lot of flexibility when transferring disks from one system to another as each
system may be set up slightly differently (for example, one system may use SCSI IDs 0-3 whilst
another uses 1-4 and another uses 0, 2, 5 and 6). In all cases, the projects will play back cor-
rectly regardless of the SCSI ID of the drive any disk is placed in and you won’t have to re-edit
projects to allow for different system configurations.
The only problem you may have is when an MO disk is transferred elsewhere and the audio
becomes ‘detached’ from the project. Basically, what you must remember is that when transfer-
ring MO disks from one system to another, try to ensure that the audio does not get ‘detached’
from the project.
