Direct Storage being bocked by Comodo

wintord · September 30, 2022, 5:18pm

Does anyone know a fix for the Direct Storage API being blocked by Comodo.

If check in the xbox game bar on windows 11 under gaming features, it states the GPU and OS supports the latest DirectStorage IO optimisations. But under drive status it states on all my nvme drives that BypassIO not Supported due to driver: cmdGuard.

If you open an elevated command prompt and type fsutil bypassIo state (drive letter):\ I get the following reply

BypassIo on "c:" is not currently supported
Status: 506 (At least one minifilter does not support bypass IO)
Driver: cmdGuard
Reason: The specified minifilter does not support bypass IO.
Storage Type: NVMe
Storage Driver: Not BypassIo Compatible

If I uninstall Comodo it will then pass the direct storage requirments. Which going forward will soon be needed once developers start adding this to there software. I could do with it now with messing about in software in my spare time.

Is there a workaround available for this issue, or does anyone know if Comodo are aware of this problem with there software blocking important windows features going forward. (its not just Comodo most anti virus programs appear to be blocking direct storage API’s at the moment, outside of windows built in virus protection.

My computer freezes randomly, I checked the event viewer and found this warning every time it happens.

Was this issue between Comodo Firewall and DirectStorage somehow resolved?
I have the same issue: BypassIO not Supported due to driver: cmdGuard

Hi sa5o,

Thank you for reporting.
Could you please tell us exactly what did and what happened ?
Also provide us the below detail:

Are you using any other security software simultaneously with CFW ?

Thanks

No the issue is still there, only a very small amount of Anti Virus programs have yet to sort this issue out. Its down to the advanced features they offer over Microsoft’s own security systems that’s built into windows.

I noticed this has been ongoing since September 2022. We are now into the best part of August 2023.

I have used comodo for well over 15years. I’m shocked there is no public solution to this.
Will it be fixed or should I just uninstall.

C:\Windows\System32>fsutil bypassIo state c:
BypassIo on "c:" is not currently supported
Status: 506 (At least one minifilter does not support bypass IO)
Driver: cmdGuard
Reason: The specified minifilter does not support bypass IO.
Storage Type: NVMe
Storage Driver: Not BypassIo Compatible

Check how it is in the Beta version of Comodo, because I have no problem on this version
