Since updating to Mountain Lion on my iMac, I have found that on two occasions, Lightroom 4.1 seems to eject the wrong disk after import. I get a warning that a disk was not ejected properly and, when I look at the Finder, I see the CF card is still 'in' and one of my externals is ejected. It is missing in Disk Utility as well so I have to power it off/on to get it to reconnect.
I've had issues with that particular external in the past (connected via FW400 off a FW800 drive) but it's always been tempermental in getting an initial connection to the Mac. Once connected it always stayed so.
Though I would see if anyone had thoughts. If it came to it, do you think a 'reinstall' of LR would be helpful? Does this require removing all traces of the program first? I'm hesitant to do that as my catalog currently has 75,000 photos though...
Thanks in advance
You might be right Geoff and it may be a sign of the external failing at this point.
The CF reader is a FW800 version and is coming off that external. It's the third in a chain of FW800 devices and I can't really plug the CF reader anywhere else without losing access to an external.
I'll look into getting a new external. Just thought it odd that this only happened after the update to Mountain Lion and thought I would check here.
