I have an external USB drive connected to my Mac mini. The Mac is running under OS X version 10.5.2.
When I try to delete anything from the external drive I get a pop-up telling me "Sorry, the operation could not be completed because an unexpected error occurred. (Error code -61)".
When I try to copy something from the internal drive to the external drive I get the message "The item <filename> could not be moved because "External" cannot be modified".
This is all not very helpful and probably a wrong setting somewhere. If I switch off the Mac and then connect the external drive to a Windows PC I have no problems writing, reading and deleting to and from the external drive.
Please can someone help me out with this? The Apple site doesn't appear to have any mention of such a problem.
