Some suggested to try format/label and choose "other" rather then
Automatic detection, and then try to provide values that would yield an
identical geometry as disks labeled by Sun... did not try this.

Some suggested upgrading the firmware by using a Sun Patch, I found out
though that Sun's patch states that: It will only upgrade Sun disks!

I went with the remaining alternatives, return the disks, if possible,
and buy Sun labeled ones.

Thanks again to all,
