I made a clean reinstall of my computer yesterday after I seemed to have hard-drive problems. Now it seems they have returned. My computer freezes for a few seconds every few minutes. I checked the Event log and discovered there was a surge of errors with the following characteristics:

  • Level: Error
  • Source: atapi
  • "The driver detected a controller error on \Device\Ide\IdePort0."
  • Binary Data:
    0000: 00100000 00000001 00000000 C004000B
    0008: 00000004 C0000185 00000000 00000000
    0010: 00000000 00000000 00000000 00000000
    0018: 00000000 00001005

How can I diagnose the problem?
I suspect my 1.5TB drive, but how can I confirm it? Currently I have 2 hard drives in my desktop - one is a brand new SSD and the other is the 1.5TB Western Digital "green" drive.


  • I don't want to diagnose only which hard drive causes the problem, but also if it's a hard-drive problem, cable problem or chipset problem.

Disconnect the one hard drive you can and see if the errors stop. If they don't its the one plugged in, if they do its the one you unplugged.
