Anyone updated to 1809 of Windows 10 and is using a Thunderbult 2 Promise Pegasus R8. (or any other TB based ones)

I am wondering if 1809 is causing issues with the drivers from Promise.

I am unable going back to previous version of Windows without doing a complete clean install, (My favorite thing in the world to do.)

Issue has now finally been found, 2.5 months later of not being able to use my R8 unit.

For Windows 10 version 1809 do the following.

"
In device manager > disk drives > Promise Pegasus SCSI disk device > properties > Policies the 'removal policy should be changed from 'Quick removal' to 'better performance' and the 'write caching' should again be enabled.
"

I wanted to post this here for any Windows users of any of Promise products.

This solution is not 100% good but it will at least make your unit semy usable. I recommend you do NOT update to 1809 as it will brick your Promise Pegasus, it will never recover even if you then plug it into older versions of Windows. I tried down to Windows 7 and it was completely bricked. Only solution to recover was to factory restart it with a Mac OS computer and sell it to a MAC OS user.

I have now sold my units and moved to a different brand due to lack of support.
