During the second disk install with 'mkdev hd' , it gives a choice immediately at the fdisk section:

The recommended default partitioning for your disk is:

a 100% "UNIX System" partition.

To select this, please type "y". To partition your disk
differently, type "n" and the "fdisk" program will let you
select other partitions.

Then 'divvy' shows up with the following table:
+-------------------+------------+--------+---+-------------+------------+
| Name | Type | New FS | # | First Block | Last Block |
+-------------------+------------+--------+---+-------------+------------+
| c0b0t1d0s0 | NON FS | no | 0 | 0| 71545476|
| c0b0t1d0s1 | NOT USED | no | 1 | -| -|
| c0b0t1d0s2 | NOT USED | no | 2 | -| -|
| c0b0t1d0s3 | NOT USED | no | 3 | -| -|
| c0b0t1d0s4 | NOT USED | no | 4 | -| -|
| c0b0t1d0s5 | NOT USED | no | 5 | -| -|
| c0b0t1d0s6 | NOT USED | no | 6 | -| -|
| hd1a | WHOLE DISK | no | 7 | 0| 71553477|
+-------------------+------------+--------+---+-------------+------------+

Erasing and creating a new FS as name u as type vxfd with the same first / last block as #0, upon i[nstall] creates my I/O error.


Am I do something wrong? I just need the second drive working as additional storage.
