Seagate sata2 issue

[Gman15]

hi guys.

2 days ago i bought the Seagate ST3250620AS Barracuda 250g 16mb cache hd.Im running it in a Asus nf680i board.Weird thing is after i loaded Windows,installed my chipset drivers,9.53,went to device manager and ran the Sata benchmark in there,i noticed that its telling me its a Sata1 and not 2.Benchmark speed i get is 68mbps,when im sure it should be close to 80mbps.my older 80g sata 2 seagate gets 75mbps,with 8mb cache,can someone please help,as im not sure if its the motherboard or hd doing this.the 80 gig shows as sata2 and not sata1.

cheers guys.

Check to see if there is a jumper on your drive. Many drives have a jumper to limit it to SATA 1..

Hi Samuknow.

i doubt it,but will check it out,do Sata drives use jumpers?

cheers.

some drives have jumper to limit their output to SATA 1 so they will work with older boards...

Next to the SATA connector, there should be four pins. If there's a jumper on the two outermost pins, then the drive has been jumpered for 1.5Gbit/sec operation.

The reason for the jumper? A certain manufacturer built chipsets that only supported 1.5Gbit/sec operation, but confused drives into thinking the chipset supported 3Gbit/sec.

One thing however. SATA II DOES NOT MEAN 3Gbit/sec!!
