Hi Joe_Lurie and thanks for this greatly informative post. Great to know about these amazing features.
As useful as many of these are, updates have some issues as they're targeted towards the audience in millions and there are umpteen number of configs and combinations in modern-day machines
I cant help but notice that I have been having an issue with my external exFAT HDD since late and up until now I was not etching it up to the windows feature update to 20H2 which I performed two+ weeks or so ago. [That too, after being warned that my device will no longer be supported after a while if I dont update and getting constant nags about this in action center. :P]
Thing is, after the update the laptop didnt boot to windows and had a startup trouble. I ran Startup repair and when it started I didnt think much of it at all. However, all out of the blue, a couple days ago, my laptop decided to conclude that the Hard Disk has a RAW filesystem and is filled up to the BRIM (both being false). Its a 2TB Seagate Backup Plus Slim Silver external exFAT drive, and was working just great up until now. Oh, btw, it shows up perfect and works great on other machines and all kinds of Operating Systems, just not anymore on my own laptop.
I did some basic troubleshooting like uninstalling driver from Device Manager -> rebooting -> reconnecting, but still observe the same behaviour.
I even went so far as to do the same with the USB Controller and Chipset drivers for my laptop, but still to no avail.
So I dug in further in and checked under Events tab, and to my horror noticed multiple instances of the "Device not migrated" event. A quick Google search told me to uninstall the device having this issue, reboot and reinstall drivers from manufacturer. But i had already tried it as mentioned above. Also, SCSI devices (or most USB external hard drives) are PnP - aka drivers are neither required nor do they exist.
I am really clueless at the current moment and curious as to why such a reliable and thoroughly tested windows update would simply fail to recognize my existing and fully functional Hard Disk.
I hope I can get some valuable assistance here, because I am really tired as it has already been almost a week and I don't want to unnecessarily format a known good HDD as it is working as confirmed on other machines and also because I have nowhere to backup the data at.
P.S.
I have already tried connecting it to other ports on the laptop and have also tried connecting other USB hard disk devices, and in all situations but this, all peripherals are working as they should.
