Hi, I have a 2tb Seagate External HDD divided into two 1tb expansions for backups and external storage, respectively. As of a few days ago I have been able to mount and access the external storage partition; however the backup partition does not mount. As a last ditch effort I'm considering reformatting the drive since I managed to retrieve everything I needed from the external storage partition. However, Disk Utility doesn't respond whenever I launch it - I'm met with a blank window which reads "loading disks", which continues for as long as 20 minutes or until I give up and force quit Disk Utility. That being said, I can't use Disk Utility to mount or reformat the partition. Is there any other method/utility I can use to mount or reformat the disk/partition? Thanks.
