Error code -8062 while copying large file in OS X 10.8.4
I have to copy a very large Time Machine backup file to another disk before resetting RAID 1 on my LaCie 4 GB 2Big drive. File is about 350 GB. After getting through about 2/3rd of it, I am getting an error saying " .. you don't have permissions to copy some items..." and when I click OK, then I get an error code - 8062.
I am using MBA Mid July 2011, OS X 10.8.4, Time Machine backup on LaCie 4 GB 2Big RAID 1 drive to FreeAgen 1 TB.
I would appreciate any thoughts on this. It has happened twice now and since the process takes a very long time, I have wasted three days on it now.
Thanks you.
