Windows 10: BypassIO not supported due to driver: EaseFilter?

I'm trying to enable Direct Storage support on my Samsung 950 and 980Pro NVMe drives for Windows 11. I get this error: BypassIO not supported due to driver. EaseFilter. I don not know what Easeflt is attached to, how to update it, or remove it and enable BypassIO.

DirectStorage issue- BypassIO not supported due to driver: FltMgr.sys

Hi,

Checking DirectStorage capabilities for my system in the Xbox Game Bar settings, GPU and OS are ok but I see the following message agaiunst my C drive:

BypassIO not supported due to driver: FltMgr.sys

Running the command "fsutil bypassio state c:\" I get the following:

Status: 506 (At least one minifilter does not support bypass IO)

Driver: FltMgr.sys

Reason: The specified minifilter does not support bypass IO.

Storage Type: NVMe

Storage Driver: Not BypassIo Compatible

I'm not finding any suggestion on the web as to how to resolve this that works for me. I have no third-party anti virus installed (just the built-in Windows 11 Defender AV solution). AFAIK the FltMgr.sys driver is a Microsoft file so not sure why it would report as not compatible.

My hardware (relevant bits anyway):

AMD 5800X3D

B550 motherboard

SSD: Sabrent Rocket 4.0 1TB (C drive) - bit locker not enabled

OS: Windows 11 Pro 22H2

Does anyone have any suggestions as to the fix?

Many thanks

H modo74,

I checked on y 3 laptops and all NVMe's are indicated as supporting BypassIO and they are listed as using these drivers, can you check if those are the drivers listed on your NVMe.

H modo74,

I am Dave, I will help you with this.

Have you checked on the support page for your NVMe for any updated drivers or firmware they may provide to try to get BypassIO supported on that NVMe?
