I understand that it is recommend that we set an external HD as a scratch disk for use with FCE projects.  Having had two extl. drives fail, and losing all my media files and prevous projects, I am looking longingly at the 1.55 TB free on my internal HD.  Is there any reason not to use that space? 


I would also back-up projects at critical stages on an external device, but I'm begining to feel I would trust the main computer more.  What are the various considerations in this please?  Thank you.  Keith

    You can do that, of course, but if you do I suggest you partition off a chunk of that space to devote to your FC needs.


    To resize the drive do the following:


    1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.


    2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.




    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)


    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.


    You should now have a new volume on the drive.


    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

    You always need a backup in case something goes awry. HDDs and SSDs will eventually fail. Having a backup is simply common sense.


    You would be better using an external drive for use with FC, but you asked about using the internal drive instead. I don't know what Mac model you have since you have not provided that information nor what version of OS X you are running. But if your computer has FW800 ports, then that should be fast enough to use.
