Possibly, or it could just be that the drive packed it in. I've dealt
with numerous drives at work there the drive just decided to die on a
whim, or sometimes with the partition table becoming corrupted.

But, this is fdisk, which I have known to have some very quirky
results when it comes to partitions defined under other partitioners
(particularly windows partitions).

Try "cfdisk /dev/sdb"
Maybe you'll have more luck.

Also, just to double-check, you don't have any card-readers etc
installed on the machine do you? If you did, sdb might actually be a
cardreader drive (and depending on the device, if there's no card they
can also give weird partition info).
