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.
