WD3200 test questions

[NozzaC]

Hi

Could you guys possibly help me interpret my HD Tach results? My system comprises a E2160 @ 3Ghz and P35-DS3L mobo.

HD Tune Pro: WDC WD3200AAKS-00SBA Benchmark

Read transfer rate
Transfer Rate Minimum : 7.2 MB/sec
Transfer Rate Maximum : 81.9 MB/sec
Transfer Rate Average : 64.0 MB/sec
Access Time : 12.7 ms
Burst Rate : 122.8 MB/sec
CPU Usage : 51.1%

Does look right? Seems to me the CPU usage is very high. I'm also wondering why there is a big speed drop for an instant (down to 7.2MB/s) at the same point in every test - about 4 seconds in. I have no other apps running. I've turned off virus checking etc.

Thanks in advance.

I think it might be an issue with HDTune (which was what I used rather than HD Tach as I said in my first post). I noticed that when I'd used HD Tune it was still taking up 50% CPU even when the test was finished and had to kill the process manually.

HD Tach results indicate a 3% CPU usage. I tried the WD tools and they gave my drive a clean bill of health. The only issue raised was that on starting the tools it said that Windows was not set up to use a drive over 137GB and would I like it to alter the registry and reboot. I said no since this sounds like the sort of thing which could mess up my boot. Any ideas on that?
