Sooo ... If you have Windows 10, and keep it updated, you can run a Linux Bash command window as a sub-system of Windows 10. I'm not talking about a "virtual machine" instance, it's actually part of Windows 10. Now I'm not sure, because I've not tried this at all, but I'm thinking it aught to be possible to mount a Linux formatted hard drive ... like the Tablo external hard drive ... using that Linux Bash sub-system to copy the Tablo contents to a new external drive by just using your existing Windows 10 PC.
Like I said ... I've not tried this at all. I'm posting this because most folks don't know that you can now open a Linux subsystem that comes with Windows 10.
To try this, you do have to enable the Linux subsystem on Windows 10. Here's how ... see: https://seniordba.wordpress.com/2017/06/05/installing-the-linux-bash-shell-on-windows-10/
If anyone here gives this method of cloning a Tablo external hard drive a try, and it works (or not), please post your results back to this forum so that others may benefit.
