    I'd like to partition my photoshop scratch drive, so as to utilize the faster outer edges of the spin. Q: In disk utilities, how is the outer part of the drive visually represented? Is the outer edge represented as the top section "A" or bottom section "B"?

    See attached screen grab. :)

    Cool, it works. :)

    I found that fancy dancy AJA software thingy I've been seeing around here (turns out it's free) and thought I'd test out four partitions.

    Partition 1 = 5GB on the outer most section of disk.
    Partition 2 = the remainder of the outer half
    Partition 3 = the remainder of the inner half
    Partition 4 = 5GB on the inner most section of disk.

    Interesting observation: Partition 4 is indeed the slowest part of the spin as expected. However, the second partition tested slightly faster. Hmmm. Anybody know what's going on here? Perhaps some sort of testing circumstance anomaly and not representational of actual performance as a photoshop scratch disk?
