Android disk size and wear level check

Use this command to get mount names and origins:

df

To get block information for data use the command:

tune2fs -l /dev/block/mmcblk0p56 (example)

If any block does not report “clean” then we can use e2fsck to clean them.

To do a check with e2fsck without changing the file system:

e2fsck -n /dev/block/mmcblk0p56 (example)
