- Yes, make sure that if you are using Windows, you have set the policy to
Quick removal.

In addition, before removing, always safely eject the device from the icon in the bottom right... If your drive has multiple partitions, right clicking and choosing eject is not always good enough.
That is down to the individual SSD and no one can say without having the schematics for your individual drive. As stated above, set it to quick removal and always safely remove the hardware.
For your last part, yes that is possible... You don't even need Windows PE, you can just use it as a standard backup machine as often as you like. [1]: https://i.sstatic.net/3mJ5O.png
