Hello Sebrant,
i recently bought the EC-CH2B from Amazon, mainly because of his support of 20Tb+ Drives.
when i plug it in it works great with smaller drives, but it fails and makes weird noises with my 22tb Red Pros...
i tried with 2 different drives, it failed with both,
i then connected them through different devices and it worked great...
i searched and saw that maybe a Firmware update is the reason?
but i would love to hear your thoughts...
thx in advance.
