I have been getting rather frequent system errors - that always seem to chain together and result in a USB hard drive removing itself... some background...
I have been using Macrium for some time without drama. For a while (don't know how long) I have been having errors that my backup drives were not available - they were fully plugged in but not recognized by Windows. My backups are on two SSD drives and they both go down at the same time. Initially I thought I had a bad USB hub - replaced it. Bad USB drives - replaced... nothing to date has worked. I have changed ports on the hub and where I plug in the hub. I have changed cables, cleaned out shadow copies of USB drives/hubs, looked for new drivers, deleted drives and let windows reinstall the drives. There are probably a number of things that I have done for better or worse that I can't remember at the present...
I have yelled at the computer in both binary and hex to no avail. I am not technical but I have found that selectively beating on the machine does sometimes work.
The pattern that I think I am finding is a COM warning ID #10016 - Local Activation Permission; followed by information on a DeviceStop ID#100; followed by mrcbt ID #100 - surprise removal - (IRP_MN_SURPRISE_REMOVAL); followed by the second mrcbt ID #100 - surprise removal - (IRP_MN_SURPRISE_REMOVAL); finally finishing with another COM warning ID #10016 - Local Activation Permission.
I am putting this on the Macrium site because of comments that Macrium was creating the shadow drives when creating the backup. I have not done a RegEdit on the key to change the permission as the info that I found was from around 2016 and was for different keys.
I am lost as to why and how to hone in on identifying the problem as opposed to the symptoms...
