What happened is not Windows having a "mini stroke".
For future reference:
In Disk Management the active lettered drive or partition is indicated by hash marks.
You left click to select the applicable drive and then right click to select menu options - including Format.
For certain partitions (e.g. Recovery) there may not be any presented options other than "Help".
Any disk related actions, especially reformatting, require very careful checking, doublechecking, and then some as each step is taken.
And it is also good practice to disconnect other drives beforehand.
Plus you can have a backup without needing to reformat drives etc. as a prelude to a "backup routine".
🤦
This was going to be THAT backup. That was the day I decided I was going to back up moving forward. I have precisely one spare drive able to hold.
And to remove extra drives just to format one is silly, nobody removed drives from their computer before formatting an external drive.
Calling all members. Do you honestly remove everything from your PC before formatting a thumb drive for example?
And as mentioned, with PCBs supposedly cracking, my card is supported but who knows, that's over $1700 risk to remove drives. Per above and I looked since, one is pretty much under the GPU and since putting in the 4090, the other two are inaccessible without removal either.
My conclusion is my Windows install is borked. As in my previous thread, there are rouge registry keys that I can't remove as User, Admin, or "mock SYSTEM". Though not unusual for some, I find remnants of folders after uninstalling an app scattered in the 20 places Windows feels like it needs to have for 1 application (Local. Roaming, App Data, Program Files. etc.. far too frequently. Devices fail to come online without saying toggling in Display Settings. Folder say they are in use and aren't. Windows occasionally opens phantom Explorer Windows.
My PC is Virus, Malware, Adware, Ransomware and any other kind of infection free you can think of. I think ive just made too many changes both software and hardware over the course of this installs lifetime. Not to mention the half baked H-build updates Windows puts out.
So I'm chalking it up to bad luck and a FUBAR Windows Install. Sometime next month I'm wiping all the drives and starting over. Fresh Windows, Fresh program installs and configurations, no importing anything (except where required ).
Welp I think this rant thread has run its course. Feel free to lock.
