    i have an imac snowleopard and my ex drive is working normal with NTFS (installed Tuxera NTFS to enable read & write on it) yet on my photoshop performance preferences, photoshop can see only my start up disk on the list and my external is not there....like there is no other option to see the other ex drive...

    even though i can read & write on it normally, not only this but i also share it on the network
    yet on my windows laptop everything is fine...

    Do you want to use the external drive as a scratch disk? Well, if PS isn't letting you, then that's a good reason not to.

    How much free space do you have on your internal drive? It's not good to have little free space left. 10% is often considered a minimum.

    It may be the NTFS format that is the problem. Do you have an HFS+ formatted external drive -- for Time Machine? -- that you could try?
    Or make an HFS+ partition.

    It's typically slower using an external. Any scratch disks needs a lot of free, preferably contiguous space. NTFS is not exactly well supported on the Mac, and definitely not officially supported by Adobe on the OSX versions of their software. I wouldn't use a volume formatted that way for a scratch disk. More ram is ideal with CS5 and 6. An ssd with some amount of free space is second best. If you're using an HDD, it needs a lot of free space to maintain performance, and it should be formatted appropriately.

    Hi, don't know if you'll be able to help me... I am kind of new to this and am not sure what to do.

    Photoshop CS5 keeps telling me that my scratch disks are full, even though I have just over 300G free on them. Now, I am trying to set up an external hard drive(1.8TB free) as a scratch disk, and Photoshop isn't picking it up?

    I read the conversation about: "It may be the NTFS format that is the problem."
    My external is also in a NTFS format. Could that be the problem?

    Not sure if this will make sense, but I really need help, as I can't continue with the design untill my scratch disks are sorted out.

    Like others have said, at a minimum setup a partition on your external drive that is formatted in HFS+ and see if Photoshop picks it up.
