yes most likely.

the kernel is detecting your partition table just fine it seems.  the
8 is the major number of the device, 16, 17... are the minor numbers,
they correlate with the major/minors of the /dev/ nodes.  the third is
the number of 1k blocks that device has, sdb1 is clearly the mac
partition table as they are almost always 31.5k

the dd trick shows you can read the device without problems, are you
sure the filesystem is not corrupt? or that the disk is not failing?


badblocks -sv /dev/sdb 

and see what happens.
