No need to use a mirror, just do single drives. ZFS checksums everything and will detect an error on a scrub even if you don't have another copy of the data to compare against.<br></blockquote></div><br><br>True. I use mirrors as I'm usually testing more than one drive. It makes it faster to fill them up, I only need to copy 1 drive worth of data. If you're only using one drive, it will work fine as well. The other test utility mentioned on the Ultimate Boot CD also sounds interesting, particularly if it can do multiple drives in parallel like ZFS can. It stinks that you can't trust even brand new hardware. HDDs have been particularly bad the past few years, even before the flood. <br>
