This doesn't look like an ext4 issue.  Did you actually check that
/dev/sdd1 exists (e.g. "ls -l /dev/sd*")?  You may need to tell the
kernel to reload the partition table and convince udev to create it.

If it does exist, can you dump the partition table with something
like "fdisk -l /dev/sdd", and read some data from the device with
e.g. "file -s /dev/sdd1" or similar?

Cheers, Andreas
