SD card only showing fraction of used space (lemmy.world)

Hello all

So I have a weird situation, where I accidentally removed an SD card before unmounting it properly and it got corrupted.

I then did a fsck which filled the card with a lot of fsck-files, but got the card working but only in a read-state.

I then used KDE's partitionmanager to repair the partition. Which made me able to write to the card again.

I then deleted all the fsck-files - I don't know if that was smart, but some googling told me it would be safe. Which is was, sort off.

Because now my SD card work. Files stay on the card - I use it in a China retro handheld - and the roms play just fine.

The weird thing is that after deleting all of the fsck-files, the card only show up as having used ~3GB, while all the roms take up ~60GB.

Does anyone know why that is? And possibly how to fix it? It is not a big deal, I just can't find an answer to why it happens or any solution. But any input would be very much appreciated.

I am a real Linux novice, so this might not be the best advice, but why not just remove the partition and repartition it?

Well I could. But copying several thousand small files back and forth just takes ages. So I was hoping there was some smart way to just repair some underlaying error.

But novice or not, it would be the most straight forward way to fix it. So thank you for your suggestion! If nothing else works I will have to anyway haha.

I’m just an old seasoned Linux user, which has tainted me with an attitude of never taking the easy solution :p
