Mount I/O error

Comment:
I'm new to Unix and am compiling a disk model of an Ultra 2 system. One of the slices (c0t8d0s1) contains 320Mb of data according to Format, but is not mounted. When I try to mount it I get the following response:
# mount /dev/dsk/c0t8d0s1 /paul1 mount: I/O error mount: cannot mount /dev/dsk/c0t8d0s1

You have to build a file system on the partition before it can be mounted.

There are 6 disks (c0t0d0, c0t2d0, c0t3d0, c0t5d0, c0t8d0, c0t9d0). According to Format, c0t8d0s1 has cylinders 1 - 361 assigned to it. I assumed there was data in this slice, but perhaps it's an empty slice. Is there any way of telling whether this slice might have data in it, without running a newfs which would erase the contents of the slice?

# fstyp /dev/dsk/c0t8d0s1
will interrogate the partition for a known file system.

Thanks for that- the response I get is: hsfs fstyp: cannot open /dev/dsk/c0t8d0s1: I/O error /dev/dsk/c0t8d0s1: I/O error Unknown_fstyp (no matches)
Does this mean a file system does not exist in c0t8d0s1 ?
