## What is Bit Rot protection?

Bit Rot, also known as data rot or silent data corruption is a data loss issue faced by disk drives today. Data on the drive may silently get corrupted without signaling an error has occurred, making bit rot more dangerous than a permanent hard drive failure.

* fix: retry detach azure disk issue ([#78700](https://github.com/kubernetes/kubernetes/pull/78700), [@andyzhangx](https://github.com/andyzhangx))
    * try to only update vm if detach a non-existing disk when got <200, error> after detach disk operation

* You don't have to use `File()` in the default value of the parameter.
* It uses a "spooled" file:
    * A file stored in memory up to a maximum size limit, and after passing this limit it will be stored in disk.
* This means that it will work well for large files like images, videos, large binaries, etc. without consuming all the memory.
* You can get metadata from the uploaded file.
