I just bought a 250 Gb Seagate FreeAgent external harddrive and am unable to erase the disk as suggested before copying any files to it.
When I go Disk Utility> Erase> and then select FreeAgent Drive on the left, the Volume Format and Name come up in grey, and the "Erase" button is not highlighted (it can't be clicked.) I am running on OS 10.3.9. Even if I weren't to Erase it before using it, when I try dragging disks onto it, a message pops up that reads, 'The item "_____" could not be moved because "FreeAgent Drive cannot be modified.' Can anyone help me?
