[SOLVED] Booting from SSD gives "Driver PNP Watchdog" BSOD Plus really slow

[WilsonSebastian]

I have two SSDs, one that I use now that works and my old one which I could not fix. When booting up my PC with the old SSD connected, the computer takes about a minute to get past the motherboard logo screen compared to ~3 seconds usually. When I booted from my good SSD with the bad one connected (it had been a long time since I had booted with the bad one connected), I was able to see the bad SSD and its files. I opened up cmd and ran

sfc /scannow /offbootdir=e:\ /offwindir=e:\windows

It was stuck at beginning scan for a long time, but eventually started checking things. I don't remember exactly what it said, but it had seen something wrong and was trying to fix it. However, I noticed it had stopped, and used diskpart to see that the volume was no longer listed as well as the disk. I restarted, but it was still gone. I've found that the only way to get my PC to recognize it for even a little while is to shutdown my PC and then turn power supply off and then on. Next time, I tried running

chkdsk e:\ /f /r

It started scanning stuff but then froze on "Examining file name linkage". Again, after a while it failed because the disk was no longer recognized.

If I boot from a USB and use diskpart, list disk shows the bad SSD there. However, list vol does not list any volumes for it.

I believe the problem lies entirely with the SSD because I have no issues with using my other one.
Does anyone know any causes for these problems and possible solutions?
Thank you.

Obvious solution is stop using old ssd, its clearly on its way out. The startup time is enough of a clue it almost dead, it showing in some places and not others is another sign.

Do you want anything off it? If not, just put it in a drawer and move on.

I'm not looking to use it, just to get data off. Also, diskpart and disk management list the drive as "healthy."

I would use this opportunity to copy them if you can? if you run into permissions problems, I would boot off a Ubuntu LIve usb and copy the files across - https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview

the boot time seems to contradict windows ssd scores

Clone the drive with ddrescue or HDDSuperClone, then run data recovery software against the clone. Avoid CHKDSK, as it will only make problems worse.
