I added a U3 digital drive (dongle type) to use as a scratch drive. The computer recognizes the drive no problem, but Photoshop (v.6) only offers C: for possible scratch drives. Any help would be appreciated.

recognition of external drives, especially in previous version of photoshop has historically been "spotty".

Since the scratch drive performance is so incredibly important to the optimal performance of photoshop, removable media simply doesn’t compare in terms of speed, and thus is generally not recommended.

With that in mind, caveat emptor. You’re better off getting another hard drive.

I’m on a laptop, so to add a drive it will undoubtedly be a usb drive, giving me the same read/write speeds (or there abouts) as any other usb device – or so it would seem to me. I am guessing that this will not be possible though. Thank you for your response.

Based on your results so far, I’d agree.

Besides, you’d want at least 2 gig set aside for Photoshops scratch file, so, I can’t see a flash style drive as a viable solution (if I understand you right).

The ability of Photoshop to recognize an external drive is, as I mentioned, flaky. Usually it’s more a function of the OS and the type of drive, but some have gotten it to work successfully, others, not.

If you can get an expansion card to provide eSATA support, then you can utilize an external HD with an eSATA interface. This sort of drive is normally seen by the computer as a standard HD, not a removable. I would imagine that the only way to achieve true SATA transfer rates would be if your eSATA expansion card was PCIe, something your computer may not support.

Not too many laptops accommodate expansion cards, unfortunately.

PCMCIA?

That’s how I upped my old laptop to USB 2.

How about Firewire connections?

On the other computer a Firewire connection seems a lot swifter than an USB one.

But there again, an external drive is an external drive unless the system thinks otherwise?

My system thinks a Firewire Lacie 250 GB HDD is internal.

It shows it that way at least.

Neat! A possible solution?

Some external drives work with both Firewire and USB options.

I always find that Firewire takes minutes whereas USB takes hours for similar type transfers but that may be a limitation of this mobo
