I have a HP Pavillion dv5224ea Laptop with Windows 7 on it. Recently I discovered a Error in Event Viewer:

The driver detected a controller error on \Device\Ide\IdePort1.

Event Viewer is recording A LOT of these errors (sometimes 13, one after the other!). Do I need to worry? What does this error mean? What device could "\Device\Ide\IdePort1" be? What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

Try running 'chkdsk c: /f' to see if there are any issues. – MrStatic Mar 8 '10 at 6:23
    
I have run chkdsk c: /f /r /b, no problems... – Kryten Mar 8 '10 at 6:29
    
Windows logs everything, so if the machine is working I wouldn't worry about it. If the machine is hanging, my guess is that you're having an issue with either a disk drive or an optical drive, most likely. Could be a loose cable or a failing drive or maybe you need to reinstall drivers. Do you have any idea what kind of device you actually have installed on IDE port 1? – goblinbox Mar 8 '10 at 6:30
    
No, I have no idea. Anyway I can find out? – Kryten Mar 8 '10 at 6:37
    
I think you should go to the laptop manufacturer's forums and ask there. The only way I know how to know for sure, other than that, would be to open it up and look. – goblinbox Mar 8 '10 at 10:10

First off, this seems to be an error for the second SATA port since numbering starts at 0 for computers and it specifies 'atapi' which is what SATA is based off of.

I suggest looking under the device manager to see what device is hooked onto port 1, and if it is the cd drive, don't worry about it. If it is a harddrive, keep semi-frequent backups.

Maybe you should check SMART logs/information of your HDD. Just google for "smart monitoring tools windows".

If they're fine, then reinstalling Windows should help. If they aren't, maybe it's a better idea to replace HDD preventively.

Edit: also it may be caused by loose SATA connector.
