Porschedrifter, just because the drives are new doesn't mean they are ok. Same goes with SMART. One of them could still be bad. It wouldn't hurt to run a diagnostic on the drives.
For the WD drives burn the Western Digital Lifeguard diagnostic tools
to a CD and boot to it.
For your Samsung drive here is a link to their diagnostic tool: http://www.samsung.com/eu/business/s...tools_eng.html
For your Hitachi drive download the OGT Diagnostic tool
For your Quantum drive, try out the Seagate Seatools
These all should be downloadable images that can be burnt to a CD. It's always recommended to run a drive diagnostic outside of the operating system.
