Noisy seek on PLEX 482448

I have just installed a PLEX 482448A in my system. I am generally happy with it but the noise it makes while seeking seems very loud compared to all other drives I have used. Using NERO CD speed utility the drive sounds like it is about to take off during the seek tests! Is this due to the very fast seek times or do I have a dud drive?
Also, I live in the US and do not have the Plextools software supplied. Where can I get this?

Thanks in advance::confused:

Yes the Plextor PX-W4824TA drives produces a rather weird noise when seeking. This is normal. Please read our Plextor FAQ for the answer to your ‘where can I get PlexTools’ question.

Thanks for your help
