Accessing external back up drive
We had to replace the hard drive in our Imac (OS X version 10.6.8). We can no longer access our Seagate external back up drive. It tells us we do not have permission. I can open the permission box. Under all the users it says their permission is "custom". If I try to change any of them to "read & write" or any other option, it automatically reverts back to "custom" We have played ping pong back & forth between Seagate & Apple Support, but both feel it is the others' problem. Anybody else have this problem or any ideas on solutions? Of course this happens as we are trying to access pics for our kids yearbook due in 2 weeks 😟....
