The 2200 and 1100 are both the same circuit board, but the 2200 supports two hard drives and the 1100 suports only one.

Currently i own 2x 2200's and 2x 1100's.

I can say as sure as death and taxes, that there are switched mode regulation stages on the main circuit board. One of which will provide 5 volts to the hard drives and many of the other 'parts' of the circuit board. There will most likely be a 3.3 Volt stage too and one to provide the CPU core voltage.

I counted 4 power inductors on one of my 1100 boards.

If you have a clear view of the circuit board you will see the hard drive power connectors. The power and regulation parts of the circuit are on the same side of the board as those connectors and they extend right to the front of the board.

You will see lots of round things, they are capacitors and situated down the same side of the board there are also 4 power inductors. For example the two near the front have 472 stampled onto the top of them.

It doesn't really mater about the details of all this, my main point is that it could be one of the above 'on board' power stages that is faulty or possibly not powerfull enough to supply your larger hard drives, or it could be the 'power brick' that you plug into the wall.

The cheapest way of finding out if it's the power brick, is simply to buy a new one with a slightly higher power rating. 12 volts @ 5 amps = 60watts They are cheap and easy to get hold of and it may solve all of your problems. It is the first thing to try after you are sure your hard drives are working.

If you don't at least try this, then there is nothing else i can suggest.

I guess you need to ask yourself how far are you prepared to go, or how much are you prepared to spend/risk on your 2200?

Another option you could try that will cost you nothing! is to fit/connect only the main hard drive and not the second drive. Obviously you will not have any mirrored data backup BUT you will only be using half of the power. If your 2200 runs fine with just 1 hard drive fitted then it is a good indicator that it's some form of power issue.

That's all i can add to help with the problem if it's a power issue.

The 2200 is a good little unit but as you have suggested maybe it's time to look for a new replacement if you are not prepared to put any effort into finding the fault.

The closest modern equivalent to the 2200 is a GOS unit, the '210' which is a twin hard drive model like the 2200.

Goodluck!
