In Destructive Record mode, recording over existing clips replaces the original audio permanently, which allows you to keep disk use to a minimum. However, if you have sufficient drive space, it is usually best to use Pro Tools in Nondestructive Record mode, to avoid losing any previously recorded material.
When defining the record range and setting pre- and post-roll, Destructive Record mode works the same as Normal (Nondestructive) mode.
Unlike the other record modes, it is not possible to cancel or undo record takes when using Destructive Record mode (see
Canceling a Record Take).
