Removed SATA 1.5 Gb/s limit jumper now computer won't boot

I bought a new computer and I'm using a hard drive that was originally in an older computer that didn't support SATA 3.0 Gb/s speed, so I had the jumper to reduce it to 1.5 Gb/s. I have it in a new computer and I just remembered that the jumper was in place to reduce speed, so I took it out, now it won't boot. I'm sure that if I were to just put the jumper back in it would work, but I would like to know if i can get it to work (BIOS recognizes the drive), or why it won't work. I'm fairly certain that my motherboard supports the SATA 3 Gb/s, because I have a core i5 750 in there and the board supports some i7's.

If you need any more information just ask.

If you move a windows installation to new hardware, it won't boot. The HAL is built at installation time specific to the base hardware in the system. Also, if your old installation was an OEM install with OEM license, then the license can't be moved to another machine. The OEM windows license is tied to the system it was installed with. If this is not OEM then you could do a repair installation of windows to rebuild the HAL and it should work. Probably has nothing to do with the jumper.
I had a new operating system installed(it's been running for weeks now), when I put the machine together. I had the computer up and running then I shut it down to change the jumper after doing so, the computer will not boot.
Make and model of the drive and describe in more detail what the boot failure is, what stage of post, or any error message. Did you make any changes in BIOS such as setting the ports to SATA mode from IDE or Legacy?
Seagate Barracuda 7200.10 ST3750640AS 750GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive (Perpendicular Recording)

Didn't make any changes in bios, but I get Pri Master Hard disk:S.M.A.R.T. Command Failed

also getting this:
Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key
Download Seatools and test the drive, the smart command failed could mean the SA area of the disk is not being read.
I ran that, and I get the following:
No hard drives found
if you believe this to be incorrect, check cables, drive power connection and jumper settings.
and then try again.


Assuming the jumper is the problem (should be)
is it even worth it to have the drive to be able to use 3.0 Gb/s? is the drive even fast enough for the 1.5 Gb/s increase to even affect the drive's performance? because if it isn't then I'll just put the jumper back on and forget this whole situation
Try it with the jumper back on, should not make a diff, unless you have to set the speed in BIOS, never saw that but you never know...
alright I'll do that, check the post above i edited it before i saw you post again.


put the jumper back in to limit it to 1.5 Gb/s and it works fine.
Most drives don't hit the 3 GB/s speed, most not even close, as with most things, that is the theoretical maximum the bus can move, a lot of other things come into play to determine the true speed. You can benchmark the disk, and in a lot of cases it probably won't even hit the 1.5. Wouldn't hurt to check the BIOS settings tho and the MoBo manual may give some hints.
Alright, yeah, it's working fine for now, I'm not going to bother with it, but I just have to say my mobo better work when i get a new drive (ssd when they become cheap)

I've dug around in the bios settings (which has been updated to the most recent) and i didn't find anything of use, in this perspective, I'll try the mobo manual sometime, but it's not too much of a concern since I'm sure the drive won't hit the speeds anyways.


thanks for the help
