Hi,

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?
