Possible to have 2x HDD in HP Nc2400?

Hi!
I installed a HDD caddy instead of the optical drive in my HP. It runs fine with a 5400rpm 120GB disc. Just got Ubuntu installed on it.

But.
As long as my normal 1,8" 60GB drive is connected nothing seems to work.
When I press F9 to access the boot menu, before I can do anything a message comes up, something like: "No boot disc present, press any key to continue".

I can have everything connected and boot from a USB-stick (Ubuntu Live-cd) but the drives don't show in Ubuntu. Could there be some hardware restriction for having two drives connected? BIOS-issue?

Thanks

 

Appears you have both the 1.8" ZIF and the 2.5" HDD competing to be the master device on the PATA channel. You can have them both running concurrently so long as one is master and one is slave. So the solution is either:

- set the 2.5" HDD to be slave. Check for jumpers on the drive and/or caddy.
- set the 1.8" Toshiba ZIF HDD to be slave mode by jumpering pin1+2 as shown here.

Worth also looking at the 2510P Owner's Lounge for more tips.

 

Thank you nando4!
Just jumpered the disk, which was a real hassle
Finally got it with some aluminium foil which I wrapped around the contact and fixed with some regular tape.
Now it boots up and I can access both disc!

Didn't stike me that I could check for the 2510p solutions.
Thanks again!

edit: I just want to post my results.
The disk i put inside is really nothing special.
I will switch to SSD in the future but I got it for $15 with shipping so it was worth a try.

Note that the scale is different since I pasted them one on the other, but the new disk is pretty much twice as fast.
