]We use SATA hard disk. Maybe something else is wrong? Thanks.
Though your hardware connection is SATA, the software interface is
probably IDE. WinXP has no in-box AHCI driver for SB700 or SB800.
To make WinXP use AHCI with AMD requires pressing F6 during setup
and giving it a driver floppy.
Check device manager for a DMA mode such as 'Ultra DMA mode 6'
shown in the attached image.
