I have some files on a SMB-mounted shared drive. Filesystem is NTFS.
Case 1: PSD (Photoshop file)
I edited the Photoshop file in Photoshop CS5.5 (also tried Photoshop CC), select File > Save. For the first time, it shows:
Write access is not granted
The file is removed from the folder (it's gone!!!). Then I select Save again, Photoshop asks me where to save the file. I select the original folder and the save action is completed successfully. On the 3rd Save, the "Write access" error is prompted again (and the file is gone, again).
Case 2: TXT (Text File)
The file can be saved, edited successfully via TextEdit or Terminal (vi, touch, echo command, etc).
Case 3: PNG
I tried to edit and save the file in Preview. It said, the file is locked, and let me select "Save Anyway" or "Cancel". I select "Save Anyway", it said:
You don't have permission to save the file
What is the cause of the issue? In Terminal with ls -al
command, it shows the permission is:
-wrx------@
and in the Permission section of the "Get Info" dialog, it said:
You have custom access
p.s. I'm using Yosemite OS X 10.10.2
p.s. A post suggested that it's the bug of SMB protocol; CIFS protocol will solve the issue. I tried, but the same issue persists.
If using SMB, the output of smbutil
is as follow:
==================================================================================================
SHARE ATTRIBUTE TYPE VALUE
==================================================================================================
RS_Share
SERVER_NAME 192.168.200.128

If using CIFS, the output of smbutil
