How do I access my second hard drive?
Hi! I am newbie, I am sorry if this a dumb question...
I speak Spanish and almost no English
How do I access my second hard drive?
This is what I have:
netra T4-1  2HDD 300GB

I speak Spanish and almost no English

to insert and remove the second or third disc machine detects with

dmesg
Also in the messages

All discs have the green light
but not detected in hot

the format command only sees a disk
with:
# Devfsadm nothing

With touch \ reconfigure turn off and turn on, no difference between the new /etc/path_to_inst and saving
