Does the disk support DMA ?
Have you enabled all the relevant DMA settings in the kernel config ?

I think it's ok, or not?
thanks for your attention. |

That's Multiword DMA, not UltraDMA.
Check your BIOS settings.
Or else read the output of dmesg from the LiveCD very closely for any clues.

I've the same disk.
It works fine until UDMA5 not if Bios is set to Auto or the UDMA6 option is chosen manually.
| Code: | /dev/hdb:
Model=Maxtor 6Y120L0, FwRev=YAR41BW0, SerialNo=Y36G1ZWE

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=240121728
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4

If I put UDMA6 the bootloader isn't able to start and the ide0 is reset when the disck is mounted.
| Code: | # grep DMA /usr/src/linux/.config
CONFIG_GENERIC_ISA_DMA=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
# CONFIG_BLK_DEV_IDEDMA_FORCED is not set
CONFIG_IDEDMA_PCI_AUTO=y
# CONFIG_IDEDMA_ONLYDISK is not set
# CONFIG_IDEDMA_PCI_WIP is not set
CONFIG_BLK_DEV_ADMA=y
CONFIG_BLK_DEV_IDEDMA=y
# CONFIG_IDEDMA_IVB is not set
CONFIG_IDEDMA_AUTO=y
# CONFIG_DMA_NONPCI is not set
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set
