WD My Book Live Duo - RAID 1 - problem with mounting disk in linux - bad block size 65536

I tried mounting a single drive in RAID1 and ran into a problem.
I was able to connect to /dev/md0 with the mdadm command, but when I used command mount /dev/md0 /mnt/wd - I’m getting an error:
wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error. dmesg may have more information after failed mount system call.

Dmesg shows me:
EXT4-fs (md0): bad block size 65536

Unfortunately, I have no idea how to get around this problem.
I’m waiting for any hints
