I am seeing similar events with my current computer and with my last computer.
My setup consists of two WD Black Edition 1TB drives:

Model=WDC WD1001FALS-00J7B0, FwRev=05.00K05, SerialNo=WD-WMATV0705568
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=50
 BuffType=unknown, BuffSize=unknown, MaxMultSect=16, MultSect=off
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=1953525168
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio3 pio4
 DMA modes:  mdma0 mdma1 mdma2
 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: Unspecified:  ATA/ATAPI-1,2,3,4,5,6,7

00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI
Controller

I also have smartmond running to periodically query the drive. In my case I
have two drives running in a mirrored configuration and this will arbitrarily
kick one of the drives out of my RAID array (using md). I just spent the last
few days recovering from a RAID event that killed the entire array (due to this
problem I believe).
