Maybe, you had some labeling on the disk? Or some partition (not starting from block 0) on it, which contained your ZFS pool. In order to ZFS to see the pool, you will need to recreate that partition first. Your earlier post shows MBR partitioning, but not partition? Perhaps you just need to remember what the partition was?
