At one point I replaced another piece of hardware that was on the same Ethernet switch as this unit and the crashes cleared up for a while. Then I suspected a flaky power adapted but haven't addressed it and then I suspected RF from my amateur radio operations and put the power cord in a ferrite core with no positive results.

I had an SATA drive on it to begin with but then decided to just use the micro-SD card. My guess that a quite large card with much excess capacity would wear level enough for long life. Well, maybe 18 months or so is "long life". For the record, the Freedom Box micro-SD card image formats the root partition as BTRFS. It wasn't a choice of mine. I've used ext2/3/4 for many years and that system has always done well for me. Fortunately this isn't a system that is critical, but it does serve some purposes. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.
