SATA speed for HP Seagate drive

Hi, this isn't about a homebuilt computer, but is about an issue I would
guess folks here know about.

I have two HP servers, ML110G5, bought about 9 months apart. Each came
with a single 250MB SATA disk.

The first had a Seagate ST3250310NS drive which identifies itself as
Model: GB0250C8045, Rev: HPG1

The second had a Western Digital WD2502ABYS drive which identifies itself
as Model: GB0250EAFYK, Rev: HPG0

Having put a pair of larger drives in the later server, I moved its WD
drive to the first server, to use as mirrored RAID, which works fine,
having the disks configured in the HP RAID as individual Legacy JBOD,
and using software RAID1 under CentOS 5.

The issue is that the Seagate Drive will only run at 1.5Gb/s, whereas the
WD will run at 3Gb/s. This is reported in the HP RAID BIOS as well as the
Linux dmesg.

I swapped the SATA signal cables to the drives, and the 1.5Gb/s rate stays
with the drive, not the port.

I have checked the Seagate drive, and the speed link is already removed,
which I thought should make it run at 3Gb/s.

Does anyone here know if this drive can be made to run at 3Gb/s? If so,
what am I missing?

Thanks in advance for any advice!

Tony
