Windows 7: Possible problem with HDD

Windows 7 64 vir

Hello guys,

I have already made a complete backup of my 500 GB SATA very slow HDD and I decided to make a complete test in order to see if the drive is really failing. So, I have downloaded both seatools from windows and for DOS (test tools made by the drive's manufacturer) and performed all kind of tests. The HDD passed all tests. So I have made a performance test with the HD Tune and results are attached. I cannot understand how Seagate drives that shows good health can have constant test speed of about 3 MB/s. There must be some kind of test result that shows the drive is failing. Is it perhaps possible that there is some kind of "software switch" to reduce the speed of the drive?

I have also made a test of seagate 80 GB IDE drive to compare the results.
Interesting is that I have this problem with the HDD after only about 2000 operating hours.

I'll try to insert it into another computer in order to check whether the drive is failing or maybe the motherboard.

Here is my performance on a 1TB Seagate with 12,000 hours of operation.

The performance of your HDD is clearly bad at the moment. If you have everything backed up then you could reformat the drive and run the speed benchmark again.
Another benchmark program is CrystalDiskMark.

I have made a lot of surfing and I have finally found the cause of my problem. It was very strange to me that only that drive started failing after only 2000 hours (possible of course but unlikely) and I found very unlikely that HD performance test would show almost straight line. This very I suspect some "software limit" and I was right. One Tom's hardware forum I have found a clue and inspected "Device manager". I have found that "Enable DMA" mode is grayed out. After that I have found Intel Chipset drivers for my motherboard even though that motherboard is from year 2005 (I thought windows 7 must already have these drivers because it is newer).

So I have installed software drivers and chosen uninstall to all items listed under IDE/ATA/ATAPI. After restart, device manager list showed something else. It showed AHCI this time. The computer was obviously faster, so I performed the test again. The results are presented in the attachment.

Thank you all who gave me advises, the problem was actually in drivers.

So this thread can be locked.
