The drive in question looked like this in the verbose boot-log:

ata2-master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire
ad4: 715404MB <WDC WD7500AAKS-00RBA0 30.04G30> at ata2-master SATA300
ad4: 1465149168 sectors [1453521C/16H/63S] 16 sectors/interrupt 1 depth
queue

I tried the patch even though it probably isn't applicable to my
problem, and unsurprisingly it didn't help. :-)

Thanks for trying to help though!
