I am having this problem. I can save sessions on my native HD and my Glyph FW 800 but not my LaCie FW 800 drive. Same message. I am using PT 11.3.1 and I have updated my iLok manager in case that had something to do with it. Going to possibly try reformatting my LaCie HD. Any help solving issue would be great!

UPDATE: I read somewhere I should restart my Mac and it worked. While doing so I also reset my SMC and PRAM for good measure. It now saves to the laCie HD. Hope this helps others!
