Sudden Significant Drop on R/W Speed of Hard Drive
Hello forum,
My PC has a Gigabyte X58A UD3R rev2.0 mobo, i7 950 CPU, GTS450 and 12GB DDR3 RAM. It is running Windows 7 64bit. There are two hard drives, both from WD:
WD10EALS-002BA0 1TB
WD5000AADS-00S9B0 500GB(Windows is on this drive)
*Both drives are 3 years old*
Recently, everything that involves hard drive R/W is slow on the system basically:
-Windows boot up took about 10mins
(no matter normal mode or safe mode)
-Files Moving/Copying/Opening/Deleting
(Avg R/W operation speed is about 1MB/s on both hard drives, sometimes it gets to 700KB/s and lower; This happen to every type of files. I even tried to copy files from one hard drive to another, it turned out that the speed is the same.)
-Application launch
(not so significant speed drop on this one though, but still its slower than before, applications that took 1sec to open now took 5sec)
What I have done:
-I used the HD Tune application to check both drives. And everything is OK(green color), no warnings or errors. Also, the speed is quite normal(About hundred and more MB per sec).
-Head into msconfig and enable only the services by Microsoft, disabled all others. Also disabled all startup things.
Note:
-I did not make any hardware changes to my computer since March
-No drivers or software is installed/removed since March
-Device manager says both drives are operating correctly and it can recognize my drive model names
Even more strange:
From what I saw from my research on the Internet shows that people with such slow HDD speed problems are always seeing their speed drops reflected in disk testing applications like HD Tune, while mine was not reflected there. This is the very major thing that leaves my head scratching.
I'm running out of things to try and I have no idea why this is happening?
Really appreciate any suggestions and possible solutions, thank you!
