The idea was to set the other pairs to RAID 1 arrays, link them with LVM (or RAID 0) into one partition, copy the data, then convert the remaining pair of disks to a RAID 1 array and grow the RAID 0 array to add the additional RAID 1 array. > However it sounds like your drive or your controller is not to be > trusted.

Suspicious is the word for it. Which is why I'm not going back to RAID 5 using my current configuration. My drives are all external USB-2, and split between some ports on front, some on back, and some on an add-on card. My guess is that I had an arrangement that was swamping the channels. I've played around with what is attached where in a manner that appears to have "fixed' that.
