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
@Microsoft What is this new "undocumented feature"?
