What happens if you add a larger hard drive to the RAID5?

What happens if you add a larger hard drive to the RAID? For example, if one of my drives dies on my 1.0TB model and I replace it with a 400gb instead of a 250gb drive? Has anyone tried this??

Nothing. If you are using bigger drives than installed the RAID will only use that amount of space which correspond with the original size of the partition on the old drive. The RAID is not able to scale its capacitiy. The GROW option of mdadm is not supported on the TeraStation. Cheers, Joerg
