Beyond installing the Intel chipset driver, the only possibilty may be a firmware update from Seagate but it is unlikely to be required.
Try testing different SATA cables and ports and make sure no other SATA devices are connected (like optical drives).
Do you have one 200GB partition?
When you say slow response time - can you explain exactly why you think it is slow?
Is this drive an OS drive or a data drive?
Actually it is quite stange as the sata does not need to have a driver, unless if a sata controller is configured as RAID or AHCI.
So i will suggest you to make sure that you have the latest BIOS version 0069.
And make sure that you have the latest drivers versions download from the website.
Try to run a check on your disk to see if everything is fine. Usually you may get your hard disk tool from the Manufacturer Seagate.
Hopefully, someone else will give some more light as well.
Hi intel people,
I have exactly the same problem as s.acer, but I use the Vertex Turbo from ocz (Rated 240 MB/s).
I use the latest firmware for the disk, and the latest Bios update for the D945GSEJT bord.
The disk is in AHCI mode with the Intel Driver, it maxes out at Read: 140 MB/s and write 120 MB/s.
