Thanks, Matthew, this works for me. I didn't have to boot the Mac, just made a folder in the Finder, deleted it and started LR. It then worked as it should.
Well this issue still exists in LR4. However it is gone in LR4.1(rc). Hope it stays in the final version of 4.1.
This bug has been fixed in the Lightroom 4.1 release, available now. To get Lightroom 4.1, go to the Help menu in Lightroom and select Check for Updates, then follow the prompts. Or, you can download Lightroom 4.1 from adobe.com.
I just spent a couple hours with this, trying all the above to no avail. (LR 4.2 on Mac OSX.8.2)
First of all, I was getting the error on my local volume (hard drive home folder), not an external drive.
Second of all, I could delete some recent photos, but none from about a year ago or older.
I found a folder each from which I could and could not delete. From Finder, I did 'Get Info' and put them side by side. I noticed that in "Permissions", the my name was on the list for Read and Write on one, but not the other. The other, in place of my name, said "BAK", which I presume was from an old backup.
I added my name to the LR catalog folder permissions, then clicked the gear and chose "apply to enclosed items". That fixed it completely.
Hope this helps somebody out!
The problem I was having with an external Volume in LR 4.3 was with OS X permissions.
1. Select the Volume
2. Get Info and unlock Sharing and Permissions
3. Change Permissions to Read and Write
4. From the Gears drop down choose "Apply to enclosed items..."
5. Hit OK at the prompt
6. Relock the Volume.
I am having the same problem as others have reported--I am on a new mac mini--with LR4.4--The problem only affects certain older folders that I have transferred from external drives. I have changed the permissions to read and write to no avail.
I thought I would be smart and create a new folder--and move the files I cannot delete--no luck I cannot move them.
I still have this problem.
LR 4.3, Mac OS 10.6.8, LR catalogue and photos on External HD
When I try to delete a file within Lightroom, it states that the external HD does not support trash. It then asks if I want to permanently delete it. When I select 'Yes' it still does not delete the file. So I'm unable to delete any files.
This occurred after I moved my Lightroom library and catalogue from one external HD to another (upgrade). To move the files, I followed Option One here: http://members.lightroomqueen.com/index.php?/Knowledgebase/Article/View/1166/187/how-do-i- move-only-my-photos-to-another-hard-drive-leaving-the-catalog-where-it-is
I then followed the solution in 44 on this page to change Permissions of that volume to Read & Write, Ignore ownership on this volume and "Apply to enclosed items..."
Still unable to delete any files within LR.
I can delete files from the Ext HD in the Finder, no problem. But not from LR.
And Heyo! It's back again in LR5. Bummer.
matthewlewis' workaround still works:
Open the EHD.
Create a New Folder on the EHD (Shift-Command-N).
Delete the folder that you just created (Command-Delete).
Problem is gone until next reboot.
I'm seeing a new wrinkle in this bug in LR5. Basically, if I encounter the bug where LR only offers to permanently delete the files instead of moving them to the Trash, it does work again once I create a new folder on the external hard drive and then delete it from the Finder and then return to LR. However, the new symptom is that if I don't first quit out of LR while performing this step in the Finder, when I return to the LR window, I find that:
* the files has indeed been removed from the catalog without my confirmation
* the removed files are not in the Trash
* the disappearance of the files does not result in any reduction in disk space usage on the external drive (and I'm expecting that deleting those hundreds of RAW files should have cleared up a few GBs worth of space).
The obvious workaround is to first quit LR5 before attempting the trick in the Finder, but does anyone have ideas how to locate the files that have gone missing on their own (so I can really permanently delete them manually)? I have maybe 16GB+ of files that seem to have just disappeared into limbo without giving me back the hard drive space (which was kind of the point of cleaning up my catalog).
I just started having this issue after upgrading to LR 5. NOT HAPPY. However, that workaround does work. It's still annoying as heck that Adobe re-introduced this issue in LR 5. I never experienced it in LR 4 or earlier, so this was a surprise.
