    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."

    on researching multiple posts about same topic it seams this error usually generate if you have a built in card reader that didn't receive a windows 10 driver update . or on upgrading from windows 7 to windows 10 while the system have a built in card reader (by built in meaning they are not plugged in through usb , but maybe soldered or hardwired to the board) so yea the forum suggests that all it takes to fix it is disable the faulty driver in device manager . however i recommend you try to find them a dedicated windows 10 driver on manufacturer's website and installing it after completely removing and deleting older ones on prompt .

    If it is a card reader that causes it, remove it for a few days and see if the error goes away. If it does, it might be worth considering getting a newer one that specifies Windows 10 support.

    Microsoft iSCSI initiator Service. Try and disable that. See what happens

    Silly Me--I was waiting for an email to let me know someone had replied. Now I see have three very prompt ones. Many Thanks:
    .
    @nIGHTmAYOR: I get about equal frequency of errors for each of the four USB ports I listed. They are all on a new ASUS z390M-Pro motherboard (specifying Windows 10x64) and the system was built about a month ago--installing 10-pro and updating (as far as I know). For each device DeviceManager's [Update Driver] reports that the "best" driver is installed. The Manufacturer is listed as "(Standard disk drives)." I cannot find anything specific for these ports on the ASUS site.
    . @swarfega: I have nothing plugged into any of the USB ports.
    .
    @Pluginz: MSiSCSI service was Manual-start and was not running. I started it, but that did not help. I changed the startup-type to Automatic and rebooted. There was no change.
    .
    I appreciate all these suggestions.

    I meant you might have to remove and unplug the whole card reader to see if the errors go away.

    Right, right, swarfega. I think opening the tower and handling the motherboard is beyond my paltry skillset. But I could disable that port in Device Manager if I knew which one. But each error specifically references one of the four USB ports I mentioned. Those errors do stop as each is disabled. I hope disabling would accomplish the kind of test you suggested.
