I was installing the buster-lite.img file to an SD card following the guide from the official website. I have done this before and because it is a small file it generally takes no more than a couple minutes. The memory card slot in my laptop is a bit sensitive so when I moved the laptop it caused the card to eject (I know silly from me). My issue if that it was clearly not finished and I can't seem to write to the SD card at all.
I am no expert with computers and the advice online is to place the card into a camera? or seem to be very involved or quite complex just to reformat the card. Other things I read lead me to think the card is knackered. I actually would like to fix this rather than just buying a new card, I know they are cheap but would be interesting to know what exactly is wrong

Sorry if this is trivial as I say I am a complete beginner.
