Some older Quantum drives are at least blacklisted for overestimating their capabilities when reporting their best PIO/DMA-Modes. Personally, i use an EX 4.5GB ok in DMA Mode, but it also claims to do UDMA (can't verify, don't have a controller for that). You should really try turning DMA off with hdparm -d 0 /dev/hdb martin
