These are parse errors, caused by an incorrect assumption that the
name you supplied was a partition name.

This means (probably) that partition a is not a ufs partition.

This suggests that your c partition is too big for the disk.
So what does the partition table info at the end of the drive look
like? What does dmesg say? I'm looking for information like this:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 35551782 0 unused 0 0 # (Cyl. 0 - 2212*)
h: 35551782 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 2212*)
da0 at ahc0 bus 0 target 8 lun 0
da0: <QUANTUM QM318000TD-SW N491> Fixed Direct Access SCSI-2 device
da0: 40.000MB/s transfers (20.000MHz, offset 8, 16bit)
da0: 17366MB (35566500 512 byte sectors: 255H 63S/T 2213C)
