Hmm. Maybe you or the other troubleshooters have already done some or all of this, we here wouldn't know, so here are a couple of things. I'm trying to keep in mind that you've replaced the MBP, this fact making it obsolete to
- Have the drives stayed mounted before on another Mac?
If they were only used with a PC: How are they formatted?
If they worked fine with another Mac:
- Does it occur also if the external screen is not connected?
- If not in Finder, do the external disks show up in Disk Utility?
If they do show up there, trash the file ~/Library/Preferences/com.apple.finder.plist, then log out and log back in.
If they do not show in Disk Utility:
- Are you running any 3rd-party apps or tools or drivers for peripherals where you can't be 200% sure that they are 100% Mountain Lion compatible? (Also check Login Items in your user account.)
- Only temporarily for test purposes, create a new user with same permissions as your current one. Log into that one and see if the problem persists. If it does, it's something systemwide in the OS X (and you can delete the user straight away again. If it doesn't, it's something in your user account. Please report here.
This may do for now...
No worries, there's no reason to fear for your data being lost.

Forgot one thing:
You said you use FireWire. Most of these drives also have a USB port. If you use this USB port, do they remain mounted?

Yes, try to connect at least one of the drives via USB instead of FW, see if it remains mounted. If it does, at least you know it's a FW issue, not a general one, and having it narrowed down - or not - along with the info above should help the final troubleshooter...:
Either way, and if it was all fine on your last computer, your MBP is "new" and still under warranty, right? So, as awkward as it might be, but you should then take it back to Apple, a store or AASP, and have them fixing or replacing it.
