i have a gigabyte GA-8I865GME motherboard with SATA I ... i bought a Seagate ST3160815AS hdd with SATA II ... i put the jumper in the correct position but still doesn't work ... not even the BIOS does not detect the hdd ... pls give me some detailed advises ... on how to install the hdd ... sorry for my bad english ...

put the jumpers back the way they were , they are for factory use only.

sata drives don't need jumper setting

how to install that drive can be found here.

I've just found this about jumper settings:

So the jumer settings CAN be changed by the user if needed.
However, if your mobo can do only 1.5 Gb/s then probably the default jumper setting should be used.

(there would be no advantage of using it on 3 Gb/s, as the max. througput is only 78 MB/s)

thats only to change the speed of the interface, not to tell the computer about slave , master settings.

sata drives do not need that one drive per cable

becuase xzoli moved those jumpers he may have set it to SATA 3.0Gb
if your motherboard does not support that speed it will not work.

the guide tells you that as well.

" SATA 3.0Gb/s. Before doing so please make sure your motherboard can support SATA 3.0Gb/s. (hyz022507) "

only if a poster understands his /her computer would i tell them to change the speed, mind you thats seagate all over.the 3gb drives i use ( samsung ) auto switch to what interface is on your board.

Confirmed: I removed the jumper and now my Linux kernel reports:

Although, I could not see any speedup, the measured transfer speed is still around 70 MB/s as before when it was working in 1.5 Gb/s mode.

So, 1.5 Gb/s mode is good enough for most commercial configs.
