I happened to be looking in dmesg and noticed the following: SCSI subsystem initialized libata version 1.02 loaded. ata_piix version 1.02 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0xC000 ctl 0xC402 bmdma 0xD000 irq 177 ata2: SATA max UDMA/133 cmd 0xC800 ctl 0xCC02 bmdma 0xD008 irq 177 ata1: dev 0 cfg 49:2f00 82:346b 83:7f01 84:4003 85:3c68 86:3e01 87:4003 88:20ff ata1: dev 0 ATA, max UDMA7, 234493056 sectors: lba48 ata1: dev 0 configured for UDMA/133 Does this mean that my SATA hard drive is operating at UDMA/133 rather than 150? Some sources say that UDMA7=UDMA/133, but some mention UDMA/150. Is there such thing as UDMA/150, or is UDMA7 one step up from UDMA/133? Could this an issue of my SATA interface not being completely supported? It's the onboard controller on an 865PE motherboard. Jonathan
