I just bought a new PC and have re-installed Photoshop7. What I need to know is which hard drive I should use as my scratch disk.
My PC has two hard drives:
40GB - holds installed software
120GB - image archive containing original and modified image files.
What I need to know is which hard drive to use as my scratch disk to optimize performance? My gut feeling is to install it on the 120GB drive.
Any advice would be appreciated.
Thanks

If you have adequate space on both of them, use the one that's faster.

Denis, I am not familiar with the term "scratch disk", but my Sony Vaio PC has two disks like yours.
I keep all photographs on Disk D, with various photo folders residing there. Works like a charm, and is very simple for this novice. The added advantage is not crowding the applications disk. |

| Seems like you ought to use the drive Photoshop is NOT on ... the 120G drive. |

I doubt it makes a difference for speed, except if the scratch files lead to fragmentation.
The best way to avoid that is to host the scratch disc "on it's own"; this is what should be done, for example, for the swap file. I keep a separate partition for the system swap file. It doesn't speed things up in terms of dividing activity by disc, since it's on the same drive, but it does mean that it's not likely to become fragmented, which does have some, albeit minor, impact on performance.
You can use a utility like partition magic to make multiple partitions on the same drive. Or you can do it with XP, but then you have to do it when formatting the drive, whereas partition magic will do it with your data in place, and is reasonably safe (still do a backup).
The real answer to your question is it probably doesn't matter much. But if you want to keep your files less fragmented, you need separate partitions, or to defrag the drives, say, weekly.
I should have added that, of course, the faster drive is the better choice, all other factors above being of lesser importance.

Two actual distinct hard drives. Had this baby custom built to specs.

Then put it on your 120gig drive but before you do that make sure you defrag the disk so the the file (scratch disk) will be in one big chunk. |

From the Adobe Photoshop CS Help File:
- For best performance, scratch disks should be on a different drive than any large files you are editing.
- Scratch disks should be on a different drive than the one used for virtual memory.
- Scratch disks should be on a local drive. That is, they should not be accessed over a network.
- Scratch disks should be conventional (non-removable) media.
- Raid disks/disk arrays are good choices for dedicated scratch disk volumes.
- Drives with scratch disks should be defragmented regularly.
Note that for you (and me) guidelines 1 and 2 conflict. We can't keep it off the drive our files are on, but neither can we keep it off our boot drive (where our virtual memory resides). In this case use the faster of the two drives.
