Given the ext4 format of the DVR storage disk, not native to either Windows or macOS, had to spend some time on this. Tried the WLS solution…that was a mess, and when everything’s finally installed, there’s no Linux mount command, of all things. Tried the Paragon Software Linux File Systems for Windows, and the Service that it installs wouldn’t start, so that one failed as well. Looked at what I’d have to do on macOS, and decided to find an alternative :-).
Made a Live CD of KNOPPIX Linux, and ran it on my PC. That actually worked. Both the source and target disk were automounted on /media, so I could simply “copy -r” all the directories under “rec” on the source disk to the same directory on the target disk, and that worked great.
Oh yeah, forgot to mention that formatting your target disk on the Tablo is a very helpful first step.
Just that easy…so I’d recommend skipping Windows and macOS and go directly to making that Live CD of your favorite Linux distribution. Or, if you already have a Linux system, virtual, or dual boot or whatever, you’re way ahead of the game :-).
Or ask Tablo to use exFAT instead of ext4…and good luck with that :-).
