An External Hard Disk is Corrupted
You have a hard disk plugged into a USB port and you find that it cannot be read. This happened in August 2020 and we suspect it was due to brownouts.
This is what I did.
- Plug HDD into Linux machine.
- Run gparted and look at the drive. See a !, right click and Information
- See: messages saying drive is having trouble and we should run chkdsk /f in Windows
- Remove HDD and plug into windows. Using File Explorer, determine which drive letter it is, as it will show up shortly after you plug it in. For us, it was H:
- Run MSDOS box (Start and run cmd)
- Execute command
chkdsk H: /f
(Where H: is the HDD as we determined above)
- This will likely take some time.
- After it finishes, it is OK to run it a second time

How to update your HP BIOS/UEFI firmware
HP has made patches available to fix all these flaws. But because we don't know exactly which consumer models are affected, you'll have to check your machine yourself by going to the HP software-and-drivers support page.
Once there, either type in your device's serial number or let the HP support website detect your model. From there, the support site will walk you through the download-and-installation process. HP has further BIOS-update instructions here.
