scratch disk

In photoshop I keep getting scratch disk is full and i can't figure out how to fix this. What do I need to do?

Make more space on your scratch disk, or add another disk as scratch. It's in the preferences. Googling "photoshop scratch disk" will teach you about what they are.

Think of it this way...
Windows has "Virtual Memory"
Adobe uses something similar; for Adobe's USE ONLY and it's called a "scratch disk"

If you only have 1 hard drive; make some more space

If you can.. Add another hard drive so the Windows Virtual disk and the Adobe Scratch Disks are on separate physical drives and you will notice an increase in speed.

Depending on your computer; it could become a LOT faster. My PC has SATA and I bought a Western Digital Raptor 10,000 rpm drive (Fastest read/write specs out when I bought it) and I noticed a HUGE improvement. I ONLY use the scratch dish for Adobe and when stitching together HUGE panoramas..

Yup,

I also use a dedicated scratch disk.

I used to use my 74 Gig WD Raptor (10,000 RPM) SATA drive and thats the best bang for the buck for scratch disk peformance. Since I wanted a dedicated scratch drive, and felt using 74 gig of it was a waste of a drive.

I ended up making the Raptor my system drive which holds the photoshop program and system files. (I have two of them on raid 1)

So,.. high end robust solution for a scratch disk... And the fastest thing ive ever used/seen in my life...

I am using one of these with 4 gigs of ram, more than enought for a scratch drive. Applying filters, batches processing, and stiching speeds are unreal.

Forgot to mention, never store important files on your RAM drive if you ever got one. I use it only, and strictly as a scratch drive.

When power is cut to a ram drive, you loose data stored on it (assuming there is no battery backup). I use the supplied battery backup (good for 1/2 day) and an APC battery system just incase. You don't really need it for a scratch drive, but some people like to store games and other non scratch type data on them.
