PC unable to read ANY HDD quickly

[cra1]

I'm unable to find any useful info on this peculiar issue. I have a HP dv9000 laptop that has been slowing down. The HDD seemed to be sluggish so i swapped it out for another, and another, all three with fresh windows vista installations. All three of them have very slow performance. I ran HDtune on all three and they all have erratic read speeds. Always starts slow at maybe 2Mb/s then surges to 50, then all the way back down again. The whole test shows this pattern on all 3 hdd's. However, when I use any of the hdd's in my other laptop, they perform flawlessly. Spin up quickly and have a perfect read curve through the whole HDtune benchmark. What could be causing this? Bad RAM? Could the sata controller go bad but still sort of work? Any input would be appreciated. Thanks.

SOLUTION: Turns out the HDD slow downs were due to the all too common DV series laptops bad CPU/GPU's. After a homebrew reflow, the laptop has started working perfectly and reading HDD's quickly again.

Your DV9000 laptop is from 2006. Here are the specs:

Your controller is likely worn out, and on top of that, it uses SATA-150, which is revision 1 (the current iteration of SATA is 3.0).

It will be time to upgrade the laptop, and it is simply showing its age.

I thought that may be the case, but i'm just surprised because the performance was smooth and quick up until recently; then it just immediately took a dive. I'll try the secondary hdd bay and see what the readings are, since i've never used it.

What with the age of your laptop another possibility is that, if they are original HDDs, or at least several years old, They could be in the first stages of failing.
I have had multiple older HDDs act similarly weeks to months before SMART notified me that they were failing. Then, they all failed in a relatively short period of time.
Those were Seagate 7200.11s, from about the time the Seagate's drives took a serious drop in reliability.
