Unfortunately, no. For systems equipped with two internal storage paths (nominally the "removeable" and "hard drive"), it is an either-or proposition.
However, keep in mind there are other mechanisms available to help you:
- The formal hard disk can be up to 60 GB (currently), while the "soft" hard disk (i.e. CF slot in a system that also has a PCMCIA) has no practical limit, and currently are available up to 32 GB.
- Whichever media is selected, you can use a sort of disk ring buffer to ensure that the most recent data is preserved (sacrificing the older data)
- Triggering the system, especially for higher speed channels, can often lead to huge space savings. Transitional recording is another option very appropriate for channels that basically "stay the same" a lot, but must be sampled fast for those few "rare" events.
- If you are using an autostart or diskstart, these can be stored in the device's flash memory, and so that it may be possible to have someone swap memory cards periodically, without needing access to a PC or the imc software.
