"Brand New", or possibly a factory refurb? We're off in low probability land, but the power supply, disk controller, or cabling could be itnermittent. Here in Oregon the outside temperatures are approaching 38C, but I assume the machine is cool, the fans are working and not choked with dust, and your air conditioner is not sagging the power line. A common computer power supply failure mode is a failing (low value) filter capacitor on one of the DC outputs. The result can be a high frequency voltage ripple on the output, which can cause intermittents during high activity on the drive. A DC voltmeter probably won't show the ripple, you need an oscilloscope. Lacking that, try the drive with a different machine and different cabling. Or bring it in to the Linux Clinic on Sunday.
