Has anyone seen this before? I'm trying to transfer my iMac's Time Machine backups from my old Seagate hard drive to my new LaCie d2 Thunderbolt 3. The old hard drive has a 1TB partition for the backups, and there is about 850GB of data on it. Yet when transferring it to the new drive, the transfer continues seemingly forever, like this: The amount of data just keeps rising and rising with the "about 5 seconds" estimate remaining for hours. It shouldn't be possible to have that much data when the source disk is only 1TB. What's going on? I've tried reformatting and trying again; the same thing happens.
