Currently there seems to be no way around the Mac Pro (5,1) shutting down power on sleep mode to USB 3 drives connected via a PCI/E card. The result is an "improper ejection" message and then the drive reconnects. Sonnet reports it's just a function of power savings in the hardware.  Will "Keep it Spinning" work on any drives (SSD, RAID, etc.) to keep them "connected"?  Running Sierra.

Thanks!

Keep Drive Spinning will prevent the drive from going into power saving mode so long as the computer itself is awake and your user is logged in. If and when your computer itself goes into its own sleep mode, the drive will be free to sleep as well.

Keep Drive Spinning is compatible with any sort of drive, so long as the drive is writable.

The Problem was the MAC internal Settings.
The MAC are goning in to sleep after 1 hour when i create in the Backgroud a Veracrypt Volume.
I would like to create it and it work around 12 hour.

But now I found the Solutions.
I used the Terminal and the "pmset"
The "Disksleep" and "autopoweroff"time was to short.
I setup to "0"
