ML115 G5 only sees SATA II drives as SATA I

[Stuart Parker]

Hi,

I have an ML115 G5 running Win 2008 x64. I have 4 drives installed on the SATA ports (not using RAID), one of which is the original 160GB drive. Despite this drive being SATA II, and the other 3 drives being SATA II, the machine is only seeing these as SATA I drives. I have installed the latest drivers from nVidia but this han't helped.

Any ideas ?

you mean SATA I by they are running at 1.5GB instead of 3GB

well it is because that embedded controller does not support 3GB for SATA HDDs

just a 3 new controllers supports 3GB for SATA

Are you sure ?? I thought it was a nforce pro 3400 chipset with an MCP55 ... which is SATA II ??

well now that you dared me... kidding ;-) I checked this
http://h18004.www1.hp.com/products/quickspecs/13013_na/13013_na.html#Technical%20Specifications

4 port Embedded SATA controller
SATA Protocol SATA 2, 3Gb/s
SATA Ports 4 internal
Port transfer rate 1.5 Gb/s total

I won't lie I don't really understand why says 3GB and transfer rate 1.5 GB....

just a wild guess (taking for a fact it supports 3GB)what if you test the controller speed with RAID enabled

also it is the firmware for the BIOS as the latest?

Just to close this off, I discovered the seagates had some tiny jumpers on them which limited the drive to SATA 150. Removed the jumpers and now running at SATA II 300.
