I purchased a Seagate Goflex home 3TB NAS system in 2012 that I now need to remove files from. I have forgotten the password sadly so after much research decided to remove the drive from the Goflex case to connect to my MacBook Pro via SATA to USB cable or the Insignia dual hard drive docking station. But the Mac won't see the drive on either of these. So, now I have a Seagate Barracuda 3.5" SATA drive that I still can't access because my Mac doesn't see it. I'm at a loss. Any help would be much appreciated.
did the goflex have more than one drive? if so its probably raid and I've never gotten a drive apart from its raid controller to mount. if it was a solo drive then encryption is your issue.
this article http://knowledge.seagate.com/articles/en_US/FAQ/214075en says the following:
Encrypted backups can only be restored using the Instant Backup software and your password. If the password is lost, then the backup cannot be restored.
if the NAS was just one drive and wasn't a backup but just naked files, i am not aware of how you could have encrypted the entire drive a la file vault so this would be a question for the seller. Poke around seagate's site to see if they have any low level disk utilities. i once got a WD SATA drive to read after everything else failed to mount or recover it using their HD utilities but i had to use a windows VM to do it. i would imagine you would start with putting it back in the go flex case with its controller and then try any seagate tools from there. Good luck.
