Scratch Disc Setup?
« on: November 08, 2007, 03:58:00 pm »

I am having a problem setting up my new Mac Pro.  Please give me some insight.
I have purchased a Mac Pro with 4 hard drives.

I have read here that placing the Photoshop CS3 program on Drive #1 (Mac HD) with all the other programs and then the scratch disc on another drive is preferred.  So - I tried to put my scratch disc on partition #1 (200GB) of drive #2 (750GB).  The second partition (about 500GB) was going to be for some file storage.  Drives #3 and #4 are stripped for the major file storage with backup to an external RAID set.

When I did this, I get a message on startup of Photoshop - "Could not initialize Photoshop because the disc is not available".  However, if I make drive #2 only one partition, it seems to work just fine.

But I do not want to use up the whole drive (750GB) just for Scratch.

What am I doing wrong?

Thanks.

I don't really know what you are doing wrong, but here is some helpful information from Adobe about memory management:

Yes, that link worked fine.  Thanks.  But, it did not address my problem.
I am trying to assign the #1 partition on drive #2 as scratch disc, but have not been able to.  For some reasoon, it does not accept it.

Jerry,
Thanks very much.
I just re - partitioned drive #2.  The first partition is about 195GB and the second partition is about 500GB.

Last time I formated both partitions using Mac OS Extended (journaled) and GUID partition table.  That did not work.

This time I formated both partitions using Mac OS Extended and Apple partition map.
This is working fine.  So now I have to go back and only change one thing at a time to see which change made it work.  Also, I will have to do some reading about what the differences are.

BUT - bottom line is I think I am all set.

Thanks for pointing me in the right direction.

Hi there,

You only need 20GB for the Scratch Partition
