My 1TB box developed a fault. The replacement has just arrived, and it's 500GB. Who do I ask for a 1TB to replace mine?
If I remember correctly, when it was noticed some time ago that the 4k box had been reduced to 500GB, the question was asked and a Mod replied that in the event of a future failure boxes would be replaced like for like. I thought it was odd at the time because they can't carry an infinite stock of 1TB boxes.
Based on that thread @Kelvin_Harding you should have been sent a 1TB replacement.
