CLEANUP DISK
Pressing CLEAN (F3) in the main UTILITIES page will take you to the CLEANUP DISK page
which allows you to clear out redundant recordings and so save valuable disk space. Pressing
F3/CLEAN shows this screen:
It is possible to have a disk full of unreferenced audio files. These are pieces of audio that have
no association with any project. These are usually created when recording. For example, you
make one recording and make a mistake. You drop in again over that, recording a new piece of
audio. If the original recording is not in another project, the audio associated with the original cue
you recorded of it has become ‘unreferenced’ and is taking up disk space needlessly. Of course,
if you keep recording over and over again on the same spot, you can fill your disk up fairly
quickly. Also, if you delete a cue from a project via an appropriate remote, you can end up with
unreferenced audio. The functions in the CLEANUP page allow you to deal with this.
The CLEANUP functions are:
CLEANUP
This will only erase unreferenced audio but will not ‘top and tail’ the cues that are valid. However,
because CLEANUP keeps all the audio that may be being referenced (no matter how small),
you may see no change or only a small change in the FREE ON DISK field because unlike
MINIMISE, if just one cue in one project uses one second of a ten minute recording, the whole
ten minutes will be kept. If you need to free up a further nine minutes and 59 seconds, use
MINIMISE.
Pressing CLEANUP will give this message:
Because audio may be being referenced by an EDIT CLIPBOARD (if the disk has been edited
via an appropriate remote or used by DD1500/DR8/DR16), you could try a cleanup and end up
with no appreciable increase in available disk space. This option allows you to select whether
you want the clipboard to be deleted as well. You should make your choice using F5 or F6 as
appropriate.
Next, you will be given a final safeguard prompt:
When performing a cleanup, you should be aware that it is possible to have a project on a
removable disk but for the audio for that project to exist on another disk (maybe the project is on
an MO but the audio associated with it is all on a fixed hard disk). If the removable ‘project’ disk
is not present on the system when you perform a cleanup, you run the risk of losing all the audio
for that project. The reason is simple...
The CLEANUP function works by searching all the projects on all the disks currently attached to
the system and it establishes what audio is being used by those projects and what is not. It then
deletes any audio NOT being referenced by those projects from the disks.
