I formatted a 128GB microsd card using Etcher with CoreElec (linux-based kodi) which created two partitions – a 512 MB FAT32 boot partition and a 115 GB ext4 storage partition. I was recently writing to the ext4 partition from my Manjaro desktop using filezilla while the card was mounted on my Amlogic device. I began to get errors trying to write to the card, so I powered down the Amlogic device and mounted the card on my Manjaro machine, but when it mounts, I cannot write to it. I have only written 15 GB to the 115 GB ext4 partition.
Did my card somehow become locked? Did my card get corrupted? How do I fix it?
