Hi All

I have got NTFS For Mac v15 running on an iMac with High Sierra 10.13.4.

I just connected a new external RAID enclosure with 4 x HGST Helium 8TB drives inside configured as a RAID 10 striped set of mirrors for a 16TB drive via USB 3.

Paragon recognised the raw drive when it was plugged in.

I selected the drive and selected "Erase".

Paragon unmounted the drive, asked for a name, warned about losing all data and for the last 2+ hours and counting, the progress bar has leapt to about 0.25% with the status step "Creating file system structures" and the drive busily flashing its activity lights and lots of disk noises and has not budged any further.

I've also asked the drive enclosure support team this, but is this normal?

How long would, what I'm guessing is a low-level erase and format, take on a 16TB drive like this?
