Drobo 5C won´t mount if TI 2021 is installed
I have a Drobo 5C that connects to my desktop computer via USB3. I just turn it on when i sync files from my computer to the Drobo, so it is not on every day. Today when i started it it did not mount, Explorer, Windows Disk Management, Directory Opus or Drobo Dashboard could not "see" the Drobo. Since i installed TI 2021 a couple a days ago i thought that the protection had kicked in and realized that i could not even launch TI 2021 when the USB cable was attached to the computer. If i unplugged the cable, TI 2021 launched.
Though i did turn of all protection and restared the computer the Drobo 5C still refused to mount. I started a laptop that don´t have TI installed at all. The Drobo mounted without issues directly.
Now i uninstalled TI 2021 from my desktop computer and plugged in my Drobo 5C again and it mounted directly.
So, TI 2021 is the issue here and i wonder if anyone know how to solve it?
I can insert a USB3 memory stick into the computers USB3 port without any issues, so there is something with the Drobo 5C that offends TI 2021. I have used this Drobo for years with earlier versions of TI and have had no issues.

Roger,
First, I'd say this is a candidate for starting a Support ticket with Acronis and providing a system report.
Second, are you able to look at Device Manager, both with and without ATI 2021 installed? Perhaps there is a clue there in the USB drivers.
Third, check power settings with and without ATI 2021 to see if there is any change in USB suspend.
Control Panel->Power Settings->Change plan settings->Change advanced power settings->USB settings
Since the issue only seems to be with the Drobo, I'm not hopeful of finding anything obvious here. What is the Drobo file system?
Have you checked the Event viewer to see if anything comes up as an error or warning?

I did file a support ticket earlier this day. Could not provide a system report since it is 26.7 MB and the max size for uploading is 25 MB. Will send it manually when they respond. :)
Nothing special that stands out in the Device Manager and the USB settings in the Power Options, iow USB selective suspend setting, is set to Enabled. The file system is NTFS.
Yes, there is warnings in the Event Viewer as per the attached images. I have noticed that when i plug in the Drobo the disk usage is 100% according to the Task Manager so i launched TI2021 and went into the A/V settings and disabled Scan external drives and that solved that issue but the Drobo never pops up as it should be doing when one attach it. So in the end it did not solve the issue.
In the log from the System you can see that Cyber Protect is involved...
Will update this post when/if it gets solved.
Thanks for chiming in! :)

Roger, you can send the system report by using the in app feedback, making sure that attach system report is selected. Say that the system report relates to the issues you are having with Drobo 5C; include the support ticket number if you have it. Also include a link to this forum thread.

I have now sent in two tickets on the support site but get no mail confirmation nor any reply. Does it even work?
I did send an in-app feedback a couple of minutes ago including the systemreport and with a link to this thread.

Thanks Roger. You should get a confirmation email for the support tickets, which should include a support ticket number. There will just be an automated confirmation of the feedback. Once you have the support ticket, advise that you have submitted system report via feedback.
