windows update to 1909 loses healthy disk

disconnecting the 6TB does not ensure that after the update I'll be able to read it
what I don't understand is why winver has no problems with the 6TB and updating to 1909 showed it as unallocated as if GPT managemant is no longer compatible with windows, but my 3TB disk which is also GPT was readable?
I'll try to update be force to 20H2 and see what happens maybe bugs of 1909 were corrected....
thank you

I have not had a drive not be readable unless there was something bad going on with it. I have connected some drives that have sat 10 years and windows reads the disk. Windows cant show files from linux though unless you install a driver for it.

one old 200gb WD that had no errors under SMART one day just quit working completely, still spins but it is dead. Total failure, and who knows why, but windows and the BIOS cant see the drive anymore. If the BIOS cant see it, then windows wont either.
I ought to put it in a portable case and see if it works. Its funny to look through a pile of old drives and see how really small they are, like 40gb, 60gb, 20gb.

thanks for your prompt answer
that is why I ran hard disk sentinel and minitools partition wizard and even chkdsk to see that everything was alright with this 6TB disk. And it was. There is no excuse for this sudden change of policy on behalf of Microsoft. Especially when it is inconsistent (my 3TB GPT managed disk was readable)
Old disks are entirely different. The whole purpose of updates is to move on and 200GB disks are really not 21st century product.
Windows has said goodbye before to few programs (requiring windows 10) and few hardware devices like SCSI
and that's the way it should be. PCs last on the average 5 years if you work everyday. When I buy a new one I replace hard disk, DVD etc
I think this is part of what we call progress

Or planned obsolescence, it depends i guess :)

200gb disks are not this century? Hooked up 2002 100gb wd ide last year for scrub on some old motherboard np. 300gb wd sata still worked fine too like 15 years old.

edit: IBM deathstars were dead of course :)

I have seen it where real old harddrives cant spin up the disk as the heads are stuck to the platters. They do park their heads in a non critical spot when shut down, so if you can get them to spin they might still be ok.
Take off the cover and see if you can spin the platters, just do not slide the arm across the disc face, the heads fly across resting on an air cushion never touching the surface in operation until parking.

Now looking at it, got two dead ibms, 2000 30gb and a 2001 45gb that was serviced once. One ibm ide 2002 100gb actually worked it seems.

All the data was moved from those 2 way back when so no need to try anything really. Pretty sure they didnt die while in a system though.
