I use an external drive quite often with time machine and recently tried to switch to it from my internal back up and got this error:

You do not have appropriate access privileges to save file “.001d4f473c4c” in folder “Seagate Tm #1”.

it says to get info on the file and see permissions....any suggestions? I cant find that file or folder anywhere.....

I need clarification on what you mean? What machine are you using and how many drives are you using for time machine? Remember, we only get what you write, so take your time and read it back-does it make sense to someone else.

Switch from external to internal backup; you mean time machine or retrieving a file from the external? Jon L

We need more info here.
  • you are currently using Time Machine on an internal hard drive?
  • The external drive you have is brand new?
  • Have you formated the new external drive yet?
What you need to do is right click your new external in Finder and Get Info.

Then tell us what's written in the Sharing and Permissions section - you'll need to click on the little triangle to expand that info.
 
ok,

I have two drives that are backed up with time machine. One internal and one external, and I would manually switch to the external once a week or so and then go back to the internal afterwards. Out of the blue, last week, i got the permissions error when trying to switch to the external drive. Under permissions, it is the same user (me) with permissions to read and write as it has always been. Therefore I do not understand what changed. I cannot repair permissions in disk utility as the button is greyed out and not able to be checked. When I formatted the external drive and then used it with time machine (extended journaled) it worked, and then did not let me switch back to the internal drive (same permissions error), so I had to reformat the internal as well. So something is still not right.

thanks

Why do you have both external and internal backups? Do you have a tower type g4 or g5? I would only use an external backup. If it goes down just replace it.

To fix the external, I would just erase it and backup again using the external only as your backup. This way you are not likely to run into the problems you mention.
I only run an external time machine backup and have had no problems.

It is best to have one drive dedicated just to time machine. If you really want another backup method, try superduper and dedicate it to it's own separate backup drive to. Jon L

that does not help. I have an internal backup for convenience and the external because it gets moved off site. The question is why I cannot switch back and forth as I was doing in the past and why is time machine giving me this permission error now?

Okay, now the obvious. Have you run disk utility? Checking not only the disk drive for problems, but run repair permissions. Jon L

Well at this point the best alternative is to reformat the drive and then see if there are any issues dealing with the drives stability. After checking to see if the drive is okay, then re backup time machine from the beginning. Everything should be as it was. The only thing different will be you will only have one day backup instead of 20 or 30 days. Unless you have other files on the drive. Jon L

This explains a fix:

Also, some people seem to have an inaccurate concept of what "Repair Permissions" does in Disk Utility. Application installers write a file containing what the intended permissions are on the installed files. When you run Repair Permission, it checks the files to make sure they are the same as the intended permissions originally recorded in the database file by the installer. So, "Repair Permissions" works for files that were installed by an installer the conforms to this convention, and therefore only works on the system disk.

It's not really "repairing" permissions, but checking them, then changing them back to the original. Without this database file, how would a utility know what was intended? Fixing permissions on a volume requires you to tell a utility what they should be.

This is what I've learned. If it's not correct, someone please correct me!
 
Good info, I would also suggest downloading the Combo-updater 10.5.6 and see if that solves the issue. Otherwise the link below has some other fixes. Jon L

I have the same problem, but I am running two external disks. One of them goes house.
Works fine for four months and suddenly began to give me the
same message, but:
It's your solution the simple way of Mac"?

What about the Mac's guys?

Sorry for my bad English.

Jorge.
 
ok,

I found a fix, whether or not is permanent I don't know, I got info on the external disk and removed the last permission entry which was for "everyone", so now all I see is me (primary user) and staff.....it worked fine in TM, I switched back and forth a couple times and voila......maybe try that....
