Hi Sander. Good to know. Indeed I think something's wrong with the enclosure, I keep getting some minimal corruption from time to time. I also use btrfs over luks. I'm considering buying a thunderbolt (I have a macbook pro) to esata converter, as bypassing the usb interface might be more stable. I imagine esata is better for btrfs then usb, correct ? Anyone here has experience with thunderbolt in linux ? My understanding it that if connected at boot time, devices should just appear as normal pci devices. Best, Miguel
