Operation Can't be Completed Because Backup Items Can't be Modified (Not a Time Machine Volume)

When attempting to move a file from an external disk to the trash, via the Finder, I receive the warning message "The operation can't be completed because backup items can't be modified." I can not move the item to the trash. I can delete the file using the rm command via Terminal. I would like to be able to delete items from this disk, using the Finder again.

I noticed this problem shortly after upgrading from OS X 10.7 to 10.7.1.

I did see the other discussions about similar problems on Time Machine disks. This external disk, which I am trying to delete from, has never been my Time Machine disk, nor has it ever been backed up via Time Machine. I do have another external disk that is used for Time Machine

There are no problems reported by the "verify disk" function in Disk Utility.

Thank you for your time.

iMac, Mac OS X (10.7)

Wow Thanks jamie80. I relaunched Finder after googling this error message and finding this thread and your post and it worked perfectly. Thanks for the excellent tip. 🙂

Another happy customer with finder relaunch - I haven't re-experienced it, but mine was created by partitioning my drive (a couple times I should say) heh

@jamie80 thx!

One other solution in case you don't have time to reboot: delete the file using 'rm' comand in Terminal.

I had the same message, but when trying to restore a file from my time capsule. Thanks for the tip. I restarted finder and was able to restore the file to my computer.

Thanks for that terminal kill suggestion. It worked well.

In my opinion the easiest way to fix this is:

1. Open up the “Terminal” application (don’t worry, it’ll be easy).

2. Type in `killall Finder`.

3. Press Enter.

Problem solved. 🙂

Non of the solutions mentioned above worked for me and, like you, I didn't want to mess with Terminal. Tried your solution and it worked. Great! Thank you so much.🙂
