Hard Disk speeds Reduced suddenly!

Specs: Windows XP SP3 Integrated

I have been running Windows XP SP3 with my newly purchased hard disk since 1 month. I observed that I was getting around 20 to 30 MB/sec speeds during file transfers between 1 partition to another e.g. c: to d:

Then after 1 month suddenly i noticed that my win xp loads very slows taking about 3 to 4 min to complete loading of programs in system tray, etc. and also when i make a c: to d: file copy then it shows only 1 to 2 MB/sec speeds and takes about 3 min to copy a 200 mb file from c: to d:

So I am very nervous regarding this sudden change in speeds of hard disk ... i even checked speeds using some hard disk utility tools and they only showed up max. 3 MB/sec speeds.

Please advise what could be the problem with my Hard Disk!!

The IDE channel(s) may have reverted to a slower setting. Don't worry - it's just Windows! I had a problem some time ago where my CDROM drive got very sluggish indeed.

See: How To Enable Direct Memory Access (DMA) In Windows

For how to check the settings and change them if necessary.

hey bro, I checked all settings in device manager in primary and secondary ide channels and they were already set to "DMA if applicable" and i had nothing to change.

And problem continues so plz advise some other thing... :(

Yes, but what was the "Current Transfer Mode" showing? "DMA if applicable" refers to what's been requested, not what it's set to.

Current Transfer Mode is showing "Not applicable".

You need to uninstall the “Primary IDE Channel” in Device Manager by selecting it and right-clicking it and selecting "Uninstall" or click the red "X" on the menubar at the top, Reboot so Windows reinstalls it, then reboot again and check the properties as before. "Current Transfer Mode" should now show "UltraDMA Mode" and will probably have a single digit like 5 in there too. Post back with results - even if it works, we like to know, and it may help others.
