Upgrading Internal Hard Drive DCX-3400

Hi all,


I know this has been discussed before, but there's so many threads that makes my head spin. I am trying to change the internal hard drive of my Motorola 3400, to a large drive, OR if it's too difficult to change the external box (now using a 160GB old HDD as expander).


My understanding is the following:

- Max HDD size is 2TB

- To install an internal drive, you first must format it via External Expander, then replace the internal

- Some DCX-3400 models had issues with external eStata drives

- Most drives work, but PVR specific drives like WD AV-GP, or Purple are best



- Can one install an internal 2TB PLUS an external 2TB for a total of 4TB?

- If 2TB is max, is it, 1+1, or could it be just 2TB internal?

- Where is the instructions on how to replace the internal HDD? Do I need any specific tools? I couldn't find it on Youtube and some links here are dead

- Could a WD Green or Blue drive be used without any issues or I must go for the AV-GP or Purple drives (those don't do error checks making recording smoother)?

- What are the issues with external drives and 3400? I just connected one, and am having some drop-out issues, but not sure if it's due to older drive or anything else? Wasn't this fixed with a firmware update?
