Hi I have a Sata hard drive with a jumper to "limit to 1.5 Gb/s

jumper it is for "3 Gb/s operation"

I am using:
Seagate Barracuda 7200.10 - 250gig Sata HDD
Gigabyte GA-P31-S3G Motherboard

I have been cleaning this pc inside and out when I found this HDD
jumper setting, at the moment it is jumpered to "limit to 1.5 Gb/s
operation". Can I unjumper it to make it "run" faster with the "3
Gb/s operation"? - would there be a problem with this?

Read the manual or online specifications for your motherboard. Does it
actually support SATA 2 (3GBps)? You don't mention a SATA daughtercard
so presumably the only SATA ports you have are on the motherboard.

What does it says for SATA support (for speed)?

Who put together your computer? They should've matched the settings on
hard disk with the mobo. Was the SATA disk perhaps migrated from an
older computer? If so, maybe the older computer only supported SATA-1
and whomever migrated the disk forgot to change the settings on the disk
when put into the new computer.

You might want to benchmark your SATA disk before and after making the
change to SATA-2.
Note that even if the disk doesn't go any faster when operating at
300MB/s, you still might get a big speed if you are using a port
multiplier and have more than one disk on the same port.
HDTune is free (but only benches the read speed, not
the write speed). You can use http://www.passmark.com/products/pt.htm
for a 30-day trial.
