July 20, 201015 yr Thanks Joe L., so yeah, I know that won't take the HPA off the drive, but since I will reformat that disk afterwards (or even use it in the unraid server anyway), I don't think it'll be a problem (even if it goes back to a Gigabyte motherboard, as it wont be part of the array anymore). reformatting will not remove the HPA. It will just format the artificially shorter size, not the actual native size. Are there any issues / precautions / steps to be taken when one changes the hardware? Or is it as simple as just powering up after the hardware change and that's it? (even though there's plenty about changing DISKS, I couldn't find anything in the wiki about hardware changes / upgrades). 1. Run a full parity check first... before you do anything else, just to make sure all the disks are working. Then... 2. Stop the array, power down, swap the new drive for the old. (new drive must be at least as big as the one it is replacing, and smaller than, or equal in size to the parity disk) 3. Power up The unRAID server will detect the disk change and will not automatically start until you press "Start" (you may need to check the checkbox under it to enable it) It will re-construct the contents of the old disk onto the new. This will take many hours, but you can use the array while it is occurring. Yes, it is as simple as that. Whatever you do, DO NOT press a button labeled as "restore" (it was present on older releases of unRAID) It is poorly labeled. It is actually an "Initialize Disk Configuration and Immediately Invalidate Parity" button and NOT what you want when you are replacing a drive.

Ok, so I guess I gotta look for and read about how to actually take it off completely. Regarding my second question, yes, I know that about the disks. What I was refering to is changing/upgrading/replacing the OTHER hardware (like in my case that I'm keeping the disks but replacing the motherboard/cpu/ram).
