I have a problem with my  WD3200AAKS (320 GB)

I own this hard drive from about 1 year ago…until 2 weeks never had a problem with it…

There are times…and many times…when my screen trembles…especialy when i play a game…

first time i thought that my monitor is the problem…but when i’ve connected another monitor to my pc…same problem…“out of range”

next time i thought that my video card is bad…so i’ve connected another video card to my pc…better than i had…and…same problem…

So…my monitor screen trembles…and after 5-6 minutes of trembelliing…suddenly all images dissapear…and my pc restarts…

I reinstaled my sistem again(windows 7) after i deleted everithing on my hard disk…and i repartitioned the hard disk…

my hard disk is working so slow…very slow…i tried to defragment…but same problems…i could’t defragment the partition where is instaled my sistem…(data transfer rate  is 3 mb/sec…and it should be far better)

So i have 2 problems about my hard disk…

1.the screen trembles…

2…and the hard is working very slow…

so what do ?? çause i am desperate

my hard disk is out of garancy…

Windows XP will downgrade a drive’s performance from DMA mode to PIO mode if it detects more than 6 CRC errors.

DMA Mode for ATA/ATAPI Devices in Windows XP:

DMA reverts to PIO:

Here are two SMART diagnostic tools.

HD Sentinel (DOS / Windows / Linux):

HDDScan for Windows:

See this article for SMART info:

I’d look for UDMA errors in the SMART report. These are said to be the result of cabling or communications issues.

As for your screen trembling, check the vertical refresh rate in your display properties. Some LCD monitors will go out of range at around 75Hz. Choose a lower refresh rate if this is the case. You can also see the vertical and horizontal scan rates via the monitor’s OSD menu.

The refresh rate is 60 Hertz

ISTM that you may have a power supply problem, possibly on the motherboard.

I’d use hardware monitor software to watch the voltages, temperatures, and fan speeds. You may find one on your motherboard CD, or you could use the following freeware:

HWMonitor - CPUID:


Open Hardware Monitor:

Alternatively, run your machine with the cover removed, and use a fan to narrow down the source of the problem, assuming it is a thermal issue.

BTW, I doubt that your hard drive is responsible.

yeah…i’ve installed Hard Disk Sentinel…and in the status of the hard disk shows

"There are 2 weak sectors found on the disk surface. They may be remapped any time in the later use of the disk.
At this point, warranty replacement of the disk is not yet possible, only if the health drops further.
Problems occurred between the communication of the disk and the host.
It is recommended to examine the log of the disk regularly. All new problems found will be logged there.

No actions needed."

Health 99%

so may the monitor be the problem…?


A faulty monitor shouldn’t cause your PC to restart.

The hardware monitors I was referring to keep track of the motherboard’s temperatures, voltages, and fan speeds. If any of the fans aren’t working, then this could give rise to temperature issues.
