Hello... So I am trying to salvage an external drive that will not show up in the Finder or Disk Utility. It's a 3TB Seagate with FW800 and mini USB ports. I've tried multiple cables on multiple ports on multiple macs with multiple versions of OSX. No dice. It does seem to turn on when supplied power and a port on a mac, I can feel the slight vibration of it. Purchased Disk Warrior which also doesn't see the disk. Poking around online got me into messing with the Terminal. Not my comfort zone but I can follow directions reasonably well. Aha! Terminal appears to see the drive, although it won't allow me to do anything based, I assume, on some kind of permissions issue. For example, I enter: Michaels-Mac-Pro:~ Mike$ diskutil repairvolume /Current Projects (this is the name of the drive) and get back: Usage: diskutil repairVolume MountPoint|DiskIdentifier|DeviceNode Repair the file system data structures of a volume. Ownership of the affected disk is required. So, although it won't let me in, this at least feels like progress insofar as the disk is being recognized. Still, that's not good enough. I don't care about salvaging the disk, I'd never trust it again, but I'd love to extract the contents. It's not quite worth a recovery fee to me, at least not yet, but this is important stuff that hadn't yet been backed up. Any and all suggestions are welcome and appreciated. Thanks!
