A reminder to use a different port (if possible) in case of USB device problems!

tl;dr — trying a different USB port fixed things...

Now, I know that you all know this. This is just another reminder that I could had used myself yesterday.

It all began when I decided to fire up an old laptop to see how it's doing. It has Ubuntu on the internal SSD, but I decided to instead use another SSD in an external enclosure — that one had W10 installed for testing and had been working fine so far.

First boot. Windows logo. Error message: inaccessible boot drive. Hmm, weird. "You are accessing the boot device to get this far, dummy!" I thought.

Second boot. Took forever to load. Went into recovery automatically. Then recovery failed. Okay. Tried to run checkdisk manually. Couldn't run that. Okaay... Tried to run cmd — no dice. What the hell?

Several more boots, trying to do the same thing and failing.

Then plugged the external SSD into my PC. Ran checkdisk — no errors. Interesting...

Booted the laptop into Ubuntu first, then plugged in the external SSD. Ran a benchmark because it seemed very slow. It got a consistent 1 MB/s. The real world speed when reading a file from it was 0.6 MB/s... Wow, such speed!

At this point I was almost certain that the drive was dying, about to stop working any second. Went back to my PC, tried to copy files there — speeds were actually normal. What the hell?!

My mind was racing and suddenly a light bulb went on in my head. I finally tried a different port on the laptop...

Voilà — the Windows desktop greeted me a few second later and everything ran flawlessly.

So yeah, sometimes it is the freaking port. Next time it's gonna be the first thing I try...

Even some USB extenders behave like that.

I use something like this to add USB mouse and keyboard to my Surface when booting WinPE.
Without it I only get the one USB-A port. Any disk on the nearest port will NOT boot, ever.
Disks will boot on the other ports but the weight of the drives in these spots is unweildy.
I've never needed to try this on my main workstation or other computers so flip a coin.
