The laptop is a Dell E5570 with a Crucial MX300 CT525MX300SSD1, last Wednesday I upgraded Windows 10 Pro to the latest major version 20H2. The upgrade rebooted twice and when it finished - partition D, which was a 312GB NTFS, became RAW.
Examining the partition data shows it's totally random indicating encryption, the first and last sectors are identical probably indicating the NTFS boot sector is still there and data is intact. The OS partition C is ok, meaning D is Opal range-encrypted.
C:\Windows\Panther\setupact.log shows in the beginning:

Windows Logs -> System (eventvwr) shows the following right after the first reboot:

A few seconds earlier it seems KB4592438 was installed (according to setupact.log), which has a documented issue here, here and MS confirmed, regarding chkdsk (which might have been executed automatically on boot). Yet this looks like a different issue surrounding SED.
TPM is enabled in the BIOS, I don't believe BitLocker was ever explicitly enabled on any of the partitions. It's possible to roll back the upgrade for 10 days, so I had to extend that setting to 30 days so not to lose the Windows.old folder. I tried rolling back on a clone disk, just to make sure it's successful, and it was. For now I can't go back since it's irreversible and I'm not sure if it'll help, the big question is whether Windows changed something in the SED/Opal subsystem, or simply giving the wrong credentials.

Drive /dev/sda Crucial_CT525MX300SSD1 is OPAL NOT LOCKED
One thing which is special about D, is that the Administrator's Documents, Pictures, Downloads etc. folders were moved (changed location) from C to D after the initial Windows installation. So this issue might be connected with 20H2 classifying C as not-encrypted, finding OS related folders on the Opal encrypted D, and somehow corrupting D in some later process.
I've read posts online regarding Windows "taking ownership" on SED/Opal for some reason, can this be the case here? This clearly seems like a severe upgrade bug. What does "Locked = N" actually mean? Is there a way to get the partition data back?
Thank you!
