Why does this happen and, most importantly, how to avoid this? You should ask this question on Security.SE. To avoid corruption you should make backups. In information technology, a backup, or the process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a data loss event. The verb ...

Photo files aren't special in this regard, any file on a computer can get corrupted. JPEGs are probably more likely to show up corruption in an obvious way than a lot of other files types though, so you may notice it more (see @pipe's comment on @alldayremix's answer). Files can be corrupted in many ways, (non SSD) hard drives can be put too close to a ...

There are multiple reasons as stated above. It can just be natural wear over time that corrupts bits of files or physical degrading. If you are continually finding photos and other files severely corrupted it can be a sign of a computer virus. If you don't want your files to be corrupted the first two ways then invest in an SSD as it won't degrade as quickly ...

There are two main causes. The first is data degradation. Bits stored on magnetic media (such as your hard disk) can lose their magnetic orientation over time, corrupting the bit. In harsher conditions (high heat and humidity) the physical media itself can start to degrade. For solid state media such as an SSD, the mechanism is different but the outcome is ...

The answer to the why this happens depends on the type of drive, type of file, filesystem and operating system used, so it's impossible to give a complete answer to this question. But regarding how to avoid this, the other answer touches on having backups - however, with file corruption like this, you need a way to identify when a particular copy of your ...

I'm not going to worry too much about how this happens, because hard disks will fail; just like anything else in this world, they aren't perfect. You can't get to a state where you're never going to lose a file. However, you can get to a state where you never lose a photo - you do this by having multiple copies on separate hard drives, including at least ...
