I work in Mac OS Mountain Lion. PSD preview doesn't update when i change psd-file placed on external hdd or flash drive (ntfs or exfat).
Сhanged psd-file in Photoshop cs6 (preview don't update).
Did you actually save the file after the "change"?
It is likely a bug in Mountain Lion's Finder or metadata code.
Photoshop updates the image when it writes the PSD, including thumbnail/preview.
This problem in Lion too, but when i use external drive with HFS it's normal.
My friend has same problem (Lion + Photoshop CS5)
Same problem with PDF files.
Now it's very difficult to detect latest version of psd-file.
Does anyone have a similar problem using not HFS file system?
Now it's with jpg preview
