HDD 0% to 100% spikes

[Denjin]

Hello everybody,i am having some issues with my HDD ( i think ) and i decided to post here in hopes we can identify the problem together and hopefully try and fix it.

The issue is this, whenever i download files or install large files ( games ) my HDD disk usage jumps from 0% to 100% ,non stop, lagging my PC a lot to the point where i can hardly click on anything. The CPU usage remains low , the ram usage remains average.

All HDD tests i made show it's in good condition, health status good and low temperatures.

MY HDD is Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM.

Any help is appreciated,thank you for your time.

PS : My HDD is not fragmented,does not have high system entropy and its not even close to full.

What exact test did you do? Did you run the seagate diagnostic; both long and short tests?

Next it would help if you posted ALL of your exact system specs; ie exact mb, exact ram, exact video card, exact pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, post the exact make and model# If you have a service tag# post that as well.

Do you have CACHEING turned off?? It sounds like it.

If I remember correctly those 7200.12s were the drives with the bad firmware.
Have you updated the firmware for the drive? If not, I would do that right away. The issue is that the drive suffers sudden death ie becomes a paperweight without the update. Here is the support page, check the ser# to be sure however the one you listed has an update.

Thanks for the replies all.

I have installed new firmware for my HDD and the spikes are still there when i download or install big files. However my PC does not lag at all anymore. It works fine even though the hdd usage jumps from 0 to 100% all the time while installing / downloading.Also i have cacheing enabled.

It seems to work ok so far ,i hope it holds. Thanks again for the help everybody !
