7811fx random freeze in hard drive access speed

I formatted my 7811fx when I got it and updated with most recent drivers. When the hard drive is put on stress, it causes the system to freeze for a second (cursor stops moving), then the system catches up for the missing second (the cursor jumps to whereever it should be if I moved it during the freeze). This happens when I access stuff in external hard drive as well (through eSATA). Could this be a faulty SATA driver or SATA interface on my 7811fx itself?

 

Are you referring to those pings in both the graphs ??

That is just some background process/service accessing the HDD intermittently....

You can run Resource Monitor and check which process accesses the HDD rather 'wildly' in the Disk Section.

You can update the chipset driver, and if AHCI is enabled, Vista might be using its native msahci.sys driver, which probably cannot be updated.

 

no... i actually experience the freezes in the system. the HD Tune pics were for reference. look how the hard drive spikes down to min 18mb at times though.

I'm using Intel ICH9M-E/M SATA AHCI which is dated 4/15/08

 

Yes, that is basically due to a background process....
An interface problems would rather cause heat issues, or massive fall in R/W rates.

You can try re-plugging the HDD into the socket....

 

well, it does cause massive fall in R/W during the busiest seek (enough to freeze the system). perhaps I should reformat my computer. hate doing it btw, takes 2 hours in my life away. I donno if re-pluggin would do anything since seeking on my external hard drive causes the same thing.

 

Monitor the HDD temp....Make sure its not over 50-55*C.

Well, Re-Plugging and then coming across the 'freezes' again would have assured you that this is not a H/W problem.
Its better than you re-format if you don't want to monitor the processes....

If it would have been an interface error, your drive would have been in PIO mode, and you would have seen very low R/W rates of about 15-20MB/s average.
