First of all, you'll always get the "using fictitious geometry" error. It doesn't affect performance. I think this is your real problem: right out of the box, the included disk has a "read only" element set which many people, particularly in the Linux world, will tell you requires a very special driver to turn off. Hogwash. Just execute a: scsiformat -w /dev/sd1 which may take half an hour, but it will completely wipe the drive, eliminating the read only feature. You can them create and label one or more partitions. I suggest you use the /stand/sysinstall options (at the bottom of the first page), which will help you create, label and format the partitions.
