My dad recently purchased Photoshop CS2 and installed it on the C: drive that came with his Dell PC (2.33GB w/2.5GB RAM). Its a Seagate 80GB IDE drive. We also installed a new Seagate Barracuda 160GB model ST3160023A. I partitioned the new HD 20GB for a scratch disk and the rest is used for file storage. The new drive was formatted in NTFS (same as the old drive).
Since we installed the new HD, Photoshop is very slow performing simple processes. For example, he took a 160MB image and ran a plugin that changes the tone to a B&W image. He ran a series of tests doing the same plugin several times. The first two times it took 8 seconds to render the image. The third time it took over 10 minutes. He ran this test process 3 times, closing Photoshop and rebooting between tests. Each time with similar results.
We removed the new HD and reset the old HD to the original configuration and repeated the tests. This time it took :08, :08, :55, :26, :26, 1:35, 1:40, 1:59, and 2:08 for the same process on the same image. A second test run, after rebooting produced similar results.
What could we have done installing the new drive that would cause Photoshop to run so slow? It's not just that plugin that runs so slow, we just used that one for consistancy in testing. Just even opening an image file can take a very long time with the new HD installed. Any ideas?

I'n not sure if I understand this right, why are you using a partioned area of D? drive for a scratch disk, as apposed to the whole disk, and which way have you set up PS for primary and secondary? in an ideal world you would have your second (spare) disk as primary and the main (OS )disk as secondary.
Another possibility is your new disk has a problem sector, or is maybe not compatable in some way with your main drive (fairly unusual) Wayne

Niot really wanting to do a complete reinstall of Windows and all the other apps on the new HD. Are you saying I should have used the whole 160GB drive as scratch disk. That's a little excessive isn't it?

you dont need to reinstall anything, go to edit/preferences/plug-ins and scratch disks and just select from there. as for the partiton, I don't see the point of partitioning the drive for PS, it doesn't need the whole drive, but it will work fine without it's own partitioned area, the problem with a partiton is that sometimes the drive will try to read/write to both sections at the same time causing a conflict, which can cause slow running and can also cause excessive wear on the HD.

OK, I understand now. You are referring to primary and secondary in relationship to the scratch disk settings in PS. Here's how we set it up.
The new drive was partitioned into two drives, D: (20GB) and E: (140GB). In PS preferences I set the scratch disk to Primary as D: and Secondary as E:
I doubt its a problem of disk incompatability. Both drives are Seagate Barracuda models, 7200 rpm
