A precise message would be helpful.

But you may be running off the end of the disk -- i.e. the FreeBSD slice may
extend past the end of the disk.

60Gb in disk manufacturers (DM) terms means 60*1000*1000*1000.
Operating systems (OS) usually take 1Gb as 1024*1024*1024
Thus 60Gb(DM) == 55.8Gb(OS) while you are perhaps looking
for 56Gb(OS)
