I'm curious to know if others have the same issue I've had with my Mac and Lightroom. Once again when I went into LR to do some work all my photos are gone except for 4 that shouldn't even be there. I've had this happen before and suspect Apple auto upgrades for the problem for some reason. I will be taking all my gear including external backups to a pro to resolve the issue as I haven't found the pics anywhere that is obvious including on my back up.
Strange strange strange.
Lightroom doesn't really have your files. It has a location that you added from or copied to. If that file is moved from that location then lightroom loses that file. I have most of my files on an external networked drive and this quite often gets disconnected it's not a problem if I take my mac to work with me i am not on my lan.
The first thing is to find out where Lightroom thinks they should be, e.g i have a couple registered as being on an sdcard. I have actually formatted the card since then so i really should remove them from lightroom. If you hover the mouse over the missing folder you may get a tool tip showing the file path. With the SDCard i can right click and show parent folder and right click on the parent folder till I see the whole path k5/dcim/104_0806/ was actually some raw files i edited in DX0 and DX0 added them in that location.
But anyway thats where lightroom believes they should be and where I should look if i want to recreate the link. Currently that card is in my camera.
With the network drive the folder 2008 is in /Volumes/4TB/Lightroom/ Thats not quite the physical location on the remote drive as the share doesn't share all the drive. If I was to attach the drive locally i'd have to find the shared root folder/ to find 4TB/Lightroom/ and the files under that.
Ok so you should be able to figure out where lightroom thinks the files should be, of course that assumes you are using a single catalog. If you start a second catalog lightroom will not know what is in the first. Catalogs actually an sqlite database file , a new catalog means a new database file.
A fairly common mistake is to say copy the files in dcim on your camera card to the Desktop add the files into lightroom and then delete the dcim folder from the desktop thinking the files are added to Lightroom now these files are not needed anymore.
If you imported as a copy then this is true lightroom tends to build a tree in the pictures folder on your account. I think it can be directly under /Pictures but I always create a Lightroom folder in Pictures first. The import dialog should show you exactly where its going to copy files too.
However the ADD option leaves the files exactly where you left them (in the dcim folder on your desktop) If you deleted that folder later and have emptied the trash then they have gone.
If you use timemachine you may have a backup where the dcim folder still existed on your desktop, i am not keen on time machine because it mainly focuses on what files you currently have and recently had, if files got deleted and timemachine starts running out of space then older versions can get deleted. It's not the same as moving to an external drive to make space on your internal drive.
Anyway first thing to do is find out where Lightroom thinks the files should be. That may solve the mystery, I hope its not on the SD Card you took from your camera and opened in your Mac.
