I have the same problem.

Also have exact problem. Had it before 10.8 but now it gets worse - file deletes after this error. Other apps works fine. Local saving also works fine. Suitcase Fusion plugin for Photoshop is disabled (read somewhere here about it causing problems but not in my case). We have huge windows server disks (3 Tb).

Adobe's "policy" or position is that saving across a network should work, and it does for most users.

What they're telling us is that if it's not working in our case, we're on our own, because they can't support or troubleshoot our network.  In other words, if you are experiencing problems working across a network, you have two choices:

!.— Make sure your network administrator is a competent professional who can fix it; or

2.— Save locally.

Seems like I found solution for myself -

I created (it didn't exist) the /etc/nsmb.conf file, with the contents:

#######

[default]

streams=no

#######

It's an Apple problem, not Adobe

Thank you for reporting here the workaround, badly+.

I wish some part of the documentation at the link you provided would actually describe what that setting does, and whether there are any downsides.

Do you (or anyone) know of documentation that describes just what that setting does?

Agreed - especially when the underlying OS and other Apps work as expected without OS modification, it points to a Photoshop application issue not an OS issue.

Noel - the SMB setting changes the way the MAC OS writes to SMB file stores - it's not optimal.

a few quick googlz for this setting and appledouble files should convince anyone this isn't a good choice.

for every file you save you will now have two forked files.

soooo if I save a file called "myfile.jpg"  - then normally you have a file on the smb vol named "myfile.jpg"

however......

once you set the smb setting discussed here you will now have instead

"._myfile.jpg" and "myfile.jpg"

Ultimately one would hope Adobe would fix it's method of saving data verses the SMB mod that throws you into the dark ages -that's just my opinion however - perhaps some may like having double files all over the server
