Photoshop: Open Lens correction filter is very slow when a NTFS formatted external disk is connected

If I try to open the Lens Correction Filter, Photoshop first access one of my external disk a long time (about 10s) and finally open the filter's windows.

If I unmount all my external disk (I actually have 2 Firewire 800 disk formatted n NTFS using TuxeraFS), then Photoshop does open immediately the window.

To summarize:
- External disk mounted. Open Photoshop, open one picture, to Filter / Lens Correction. Photoshop will access the disk a long time a finally open the window

- No External disk mounted. Open Photoshop, open one picture, to Filter / ens Correction. Photosop will immediately open the Window.

Note the disk are NOT in the scratch disk list.

Any idea ?

I am using Photoshop 12.1 x86 on MacOSX 10.6.8

Lens Correction (and other, similar plugins) are checking the connected disks for how much space is available -- because the plugins maintain their own scratch independent of Photoshop (yes, I know, that's not optimal, but just the way it is right now). If the disk is slow, or misbehaving, then it may take a few seconds to respond.

Humm. It is at least a good explanation.

It looks to me a "bug". Plug-ins delivered with Photoshop should take care of Photoshop settings.

PS: Having 8 GB memory to edit < 10 Megapixel pictures is still not enough...

Thanks for your answer.

Yes, I'd prefer if the plugins just used Photoshop's scratch - but that's not the way they were written, and changing it will take time.

I believe this problem is exacerbated by NTFS volumes using some 3rd party utilities:

Slow performance | Liquify | Photoshop CS5 | Mac OS: http://adobe.ly/iASs8O

Sounds like "TuxeraFS" has similar issues.

Using Mac standard formatted volumes, AFAIK, doesn't exhibit this problem.

Well, the plugins still make the drives spin up when they shouldn't. (yes, I want to see this one fixed)
