Todd The reason I'm reusing a disk is not because of hardware failures, but rather because I've abandoned a particular use for that disk, maybe changed operating systems, maybe tried something using ZFS and want to change to some other techonology. I know that the best way to reclaim a disk after read-failures is to wipe it with zeros, and this takes days. And by the way, I typically use only WD disks, not seagate. Thanks for the confirmation.
