Help lol! Hard drive problems...

[ElectroBlaster]

I recently bought a new shuttle-like barebones setup and I hate the way it all fits together, I had to put an hard drive upside down into this little cage thing as it seems thats the only way it can go in! Anyway this drive was perfectly ok in the old machine I had it in. I decided to check systems temps with speedfan and noticed the drive reports a warning next to "seek error rate" the readings are:

Value-100
Worst-1

The drive is an older quantum/maxtor, the d740x model in an 80gig size. It doesnt knock, rattle or throw up bad sectors so im
I have just dished out a maxtor cd diagnostic thing and the drive passed the 90second test with flying colours so now im doing a full scan test! Cant think of anything else to try tbh...

Couple of things I did today, I turned on the acoustic stuff to make the drive quiet as it was annoyingly loud. Also I did an in depth report using speedfan and this drive had failed the smart test sometime in the past, but is perfectly ok now?

Everything else checks out. I bought this drive second hand off the mm a while back and was placed in one of my systems that can take 8 hard drives, had it chained to two other maxtor's and a western digital drive, speedfan always reported no faults so somewhere between swapping it from that system to this new one has caused a problem.
