Windows 10: Event 507 - Completing a failed non-ReadWrite SCSI SRB request.

Since Win 10 1909 dropped I've been getting hundreds of event log messages...





...Device manager does not show problems. I have run DISM, SFC and CHKDSK with no problems highlighted.


Any ideas?

IOCTL_SCSI_PASS_THROUGH_DIRECT + Failing non-ReadWrite SCSI SRB req

Windows 10 x 64 (1903 18362.388)a. Event Log showing: Error, EventID 521 : The miniport logged an event.b. Event Log showing: Error, EventID 507 : Completing a failed non-ReadWrite SCSI SRB requestand c. when trying to update CD-ROM firmware, ProcMon is showing:IOCTL_SCSI_PASS_THROUGH_DIRECT Error: FAST IO DISALLOWEDI found page " Error Handling in SCSI Miniport Drivers " on IOCTL_SCSI_PASS_THROUGH (ntddscsi.h) - Windows drivers | Microsoft Docs

Now, not being an expert, could it be that some SCSI related driver is missing?

How to check and where to download ?

Thanks!

 

Unending EventViewer Error 507: failed non-ReadWrite SCSI SRB request

I have an ASUS Z390M-pro Wireless motherboard, a Samsung EVO 970 Pro SSD (boot), two separate HDD's with my Desktop junction-pointed to one, and Windows10x64 version 1903. No other storage.

• I keep getting EventViewer Error 507 "Completing a failed non-ReadWrite SCSI SRB request," about 30+ per second when idle. The system is about 1 month new and I do not know how long this has been going on, perhaps since the beginning--the log truncates at about 12,000 entries. The log is [Applications and Services Logs -> Microsoft -> Windows -> StorDiag -> Microsoft-Windows-Storage-ClassPnP/Operational]..
• I can find nothing useful on the internet except that StorDiag is a new Windows feature. Following an example, I ran
  > stordiag.exe -collectEtw -checkFSConsistency -out c:\users\john\desktop
  There were no printed errors and casually browsing the output folder Desktop/StorDiag showed nothing bad. chkdsk and sfc /scannow also come up errorless.

I know nothing here. Does anyone know what could be going on? Any help woud be appreciated.

Thanks to Mark Berry in his post: StorDiag Errors after Windows 10 Upgrade | MCB Systems I have discovered that if I disable certain USB devices, the errors stop. Specifically, Device Manager shows the following devices:

• Disk Drives
  - Generic- Compact Flash USB Device
  - Generic- MS/MS-Pro USB Device
  - Generic- SD/MMC USB Device
  - Generic- SMxD-Picture USB Device
  [...]

If I disable all of them the 507 Errors stop--in fact no more entries are logged. And windows states that the best driver is already installed, for each--but "there may be better drivers on the Mfr website."

 

Event ID 504 and 507 from StorDiag with Windows 10

On a system that sfc, chkdsk is not showing any errors and was clean built last week.

Looking into the event viewer looking at the logs in Microsoft-Windows-Storage-ClassPnP/Operational

I see several error messages with source StorDiag looking at Flash Drives - and none are connected during each start up.

Completing a failed IOCTL request. - Error 504 (12 times)

Completing a failed non-ReadWrite SCSI SRB request - Error 507 (12 times)

All is for the same serial number device

SerialNumber
37270751DBAF002518491

@Microsoft What is this new "undocumented feature"?
