Error when selecting volume

Question

Hello,
I just restarted my Maxtor external hard disk (which I use for time machine) because my Mac did not recognize it anymore.
Now it does but I get an error when selecting the volume for Time Machine. The error says:
"The file '.0011246f8842' can not be saved in the map 'Time Machine-reservekopieen'."
Does anybody have a clue what I need to do to get my Time Machine working again?
Thanks!
BB

Hi, and welcome to the forums.
I'm not sure if that's the same message, but it sounds like a common permissions problem.
Try this: Open the Terminal app (in your Applications/Utilities folder).
In Terminal, the prompt looks like this: user-xxxxxx:~ <your name>$
(where <your name> is your short user name). It's followed by a non-blinking block cursor (unless it's been changed via Terminal > Preferences).
At the prompt, type the following exactly as shown, substituting the name of your TM drive exactly, including any spaces, between the quotes:
sudo chmod 644 /volumes/"TM drive name"/.0011246f8842
Press Return. You'll get some warnings and a request for your Administrator's password. Type it in (it won't be displayed) and press Return again.
Then try a +Back Up Now.+
