Second time, the stressor (copying a 5 gig drive image to it) the machine held up, but got many DMA WRITE errors to ad6 ... below is the smartctl output on that drive, but I don't see anything other than the DMA WRITE errors, though I confess to not being really up on what smartctl outputs ... lighty# ./smartctl -a /dev/ad6 smartctl version 5.33 [i386-portbld-freebsd6.0] Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: SAMSUNG HD160JJ Serial Number: S08HJ1MYC31118 Firmware Version: ZM100-33 User Capacity: 160,041,885,696 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: ATA/ATAPI-7 T13 1532D revision 4a Local Time is: Mon Feb 20 08:36:15 2006 CST SMART support is: Available - device has SMART capability.
