[Improvement] disk.py should detect whether the SD card is write protected

[radujipa]

It may be often the case that the Lock switch on a typical SD card had been set either by mistake or by simply inserting the card in the used reader. An appropriate error message should inform the user this has happened.

Perhaps an image could be used to better illustrate what the problem was with the card.

Good idea! Any cross platform way to detect if the card is write protected? dd 1000 bytes?

As far as I've seen, it should be quite simple actually. dd may say something like Error writing file: 19 The media is write protected (on Windows anyway) - needs research

Error messages are now more informative: https://github.com/KanoComputing/kano-burners/commit/415a39bafccec43443aa0f7d275a7e000242b972 https://github.com/KanoComputing/kano-burners/commit/1fa871eeb32b741eeab9cff35aeebaaca0facb97

However at present the downloaded image is still deleted, so users will have to download it again, which is not doubt annoying.

@rluz To test, try with the lock slid to write only.

• The error message should be informative
• The SD card should not be written.
