Answer #2
found in net..
Specify one or more hard drive partitions that have enough free space–approximately three to five times the file size of the largest image and at least ten times the size of the largest bitmap-mode image–as scratch disks. Don’t specify a network drive or removable media such as a Zip or JAZ drive. Photoshop 6.x can create 200 GB of scratch disk files on up to four hard disk partitions; Photoshop 7.0 can create an unlimited number of scratch disk files, limited only by hard disk space.
To set the Scratch Disk preference:
Choose Edit > Preferences > Plug-Ins & Scratch Disks.
Choose the drive that has the most free space from the First pop-up menu.
Choose a second, third, or fourth drive, if available, from the Second, Third, or Fourth pop-up menus.
Click OK.
Restart Photoshop.

You shouldn’t do that while PS is running!
