comment Recovering mismatched sectors in a RAID array
And yes, there are multiple versions of the data and no way to automatically determine which one is right. That's why the system doesn't try to repair the inconsistency automatically, but leaves it for a human to examine manually instead.

comment Recovering mismatched sectors in a RAID array
I wouldn't say it's "almost certainly" the checksum is wrong. If there's a discrepancy, it's probably because of corruption on one of the drives, and that could happen on any of them. (The alternative is a bug in the kernel code that calculates the checksum, but that code is well-tested and is the same for everyone, so there'd be mismatches on lots of arrays if that were the problem.)

comment Recovering mismatched sectors in a RAID array
There is alternate data, even with RAID5: it's what you get by ignoring the data from one of the disks (as if it had failed) and recomputing it based on the checksum and the other disks. It's even possible for that version of the data to be the "correct" one.

comment Restore EFI boot partition
Note that efibootmgr will only work if the system has been booted in EFI mode. Make sure your liveUSB supports EFI booting (it should have an EFI/boot/bootx64.efi file) and that you're actually booting it that way, not in legacy BIOS emulation mode.

comment When was my machine last touched?
Input device files' timestamps don't change when you move the mouse or press a key. The timestamp is part of the inode in the filesystem, which is unrelated to the driver that actually handles the input.

comment How do multiple boot loaders work on an EFI system partition
Many people seem to think that UEFI is another name for Secure Boot, but it isn't. Secure Boot is just a feature of newer UEFI implementations. This question is about UEFI but isn't related to Secure Boot.

comment NVIDIA Proprietary Driver on Debian Jessie Problems
You don't need this entire xorg.conf file on a modern Xorg installation; just the "Device" section is sufficient to tell it which driver to use. It can autodetect the rest.

Yeah, that's better.

comment In what shared library is read()?
Point is, the wrapper function is in a shared library (specifically, libc). It's not right to say that no shared libraries are involved.
