Computer crashing

Hi guys, I have 3 drives installed and my 3rd drive (F drive) which is 250gb i think it is having some problems recently.. i try to move a file to F drive and my computer freezes up and when i go to Event Viewer it gives me this message:

An error was detected on device \Device\Harddisk1\D during a paging operation.

So i dont know what to do now, Is there any free software that i can run on it ? And if the hard disk is damaged in any way then is it possible for a software to block the part of the harddrive which is bad and use that part which is still good ? Because this issue only started to arise once the harddrive was 90% full.. after that i deleted a few files but still i have the same problem.

Also when i try to run Disk Defragmenter it says "Disk defragmenter has detected that chkdsk is scheduled to run on Volume F Please run chkdsk /f"

But i've restarted my computer many times it always ran chkdsk before logging on and it found alot of errors on F drive and then the chkdsk is completed but the error is still not going away so i could defragment my drive.

If you didn't run chkdsk /r to repair it, then do that. Otherwise,
download the manufacturer's diagnostic tools instead of using chkdsk. Create a boot disk with it and run it. That's the manufacturer of the HD itself, not the PC.

Oh okey im running the chkdsk /r on drive F right now

It stops at 17% in stage 4..

Then go to plan B. Download the manufacturer's diagnostic tools.

Boot disk? As in ill be needing a floopy for it? My floopy drive isnt working i havent used it in ages.

Anyway the chkdsk was working but very very slowly it went from 17% to 30% in like 1 hour. Anyway now im running it again and it stops in stage 2 and says An unspecified error occurred.

A boot disk doesn't have to be a floppy. A CD is fine. In some cases a USB drive is good too.

I dont know which diagnostic tools am i supposed to download? I have Seagate harddrive.. can you tell me which one from the seagate website i have to download.

Click on the EN under ISO image in the right column.
Burn the image to a CD and boot the machine with it.

Thanks alot don. Will try that
