Five minutes sounds right to me. That’s the standard in the instructions IIRC. You might even go down to 1 or 2 minutes in a USB enclosure.
This is the thread, I’m sure you have already been reading it.
I have not tried it on an EARS drive but other apparently have.
I have kept the bootable thumb drive that I made from the instructions. They are so cheap its worth having a dedicated one. Added HDSentinel DOS to it, and used that for checking drives on a server that had motherboard mirror raid.
