Hi.
I have two new 3TB disks that I'm testing prior to installing in a production
server. I created a zpool mirror, dumped a bunch of data to the pool and ran a
scrub. I got back numerous CKSUM errors, the same number on each drive. I'm
guessing this is not a problem with my 3TB drives but a controller or some
other hardware problem. Is this a correct assumption?
The PC where I'm running this test is using a GA-E7AUM-DS2H mainboard and
non-ecc memory.
