Link2SD: Mount script cannot be created

After making a 1744MB ext2 partition on my 4GB MicroSD with the Aparted app (since my Windows SD slot is broken) and trying to select ext2 when I start Link2SD I always get the error: > Mount script cannot be created > > mount: Invalid argument I tried to delete busybox from system/xbin to install a newer version, but /system won't mount as Read-Write. How do I fix this? EDIT: I'm using KingRoot EDIT 2: So I made an ext4 partition instead, and now it says > Mount script cannot be created > > mount: Read-only file system and I tried running e2fsck -fpDC0 /dev/block/mmcblk1p2 in terminal emulator (seen here as a solution) and I got the output: ` e2fsck: Internal SD card is not found, now mount manually e2fsck: save_log_to_file error /dev/block/mmcblk1p2: |== /dev/block/mmcblk1p2: |============================= /dev/block/mmcblk1p2: |=============================` `/dev/block/mmcblk1p2: 12/116400 files (0.0% non-conti guous) 16193/465096 blocks`
