Hello Roy It is unlikely that a driver or anything in the operating system will change the link speed. The link speed is negotiated before the operating system is loaded. This is likely just a compatibility issue with the HDD firmware and whatever device is acting as the SATA controller. Updating firmware and BIOS on the HDDs, system board, and SATA controller may help resolve communication issues. Yes, the T605 supports speeds greater than 1.5Mb/s. Thanks
Hi All, When running : "dmeg | grep ata1", I'm getting the following: ata1: SATA max UDMA/133 mmio m8192[NAME] port 0xee2fe000 irq 10ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 320)ata1.00: ATA-7: ST3160812AS, 3.ADJ, max UDMA/133ata1.00: 312500000 sectors, multi 8: LBA48 NCQ (depth 0/32)ata1.00: configured for UDMA/133 Checking the HD (ST3160812AS) spec shows it can do 3.0Gbps. I have two question relate to my two T605 poweredge servers: 1) Does the T605 support SATA speeds beyond 1.5 ?2) If so, do I need to have a special linux driver to get the extra speed  ? Thank you, Roy
On two PowerEdge T605 I get for the internal disk : SATA link up 1.5 Gbps. Is 
this a HW<=>drivers compatibility issue ?
