Hello out there!
Thanks for your work on antiX - It's great, i love it!

I just installed antiX-15 on my beloved IBM T23 (160GHDD+1GB RAM) and did an apt-get dist-upgrade.
The machine runs nicely.
Now I want to access a second HDD that is plugged into the IBM's-Ultrabay-slot.
(It has been there since i powered up the machine, i did not dare any hot-plugging...)
I can hear this drive spinning, but how can I access it, since i don't know the /dev/sdX ?

Yeah! I just answered the question by myself... __{{emoticon}}__
In Terminal:
I used sudo gparted, checked which devices were there and see: It's called /dev/sdb !
Ok, then i created the target directories in /mnt
sudo mkdir /mnt/dirname1
sudo mkdir /mnt/dirname2
...
and just mounted the drive there:
sudo mount /dev/sdb1 /mnt/dirname1

Actually this is basic stuff, but i dicided to post it, since it took me a bit to get there. May it help!

--------
What you are looking for is the point you are looking from (Mooji)

To check newly plugged in devices, __{{emoticon}}__

or to just look at drives, you can :
or for a tiny bit more info
or lsblk, or lsusb, lspci or some other way, depending on what kind of device it is.
There are usually many ways to do stuff. Go play with them, and see which one you like.

Thanks a lot for the hints!
