My computer would not shut down - hard drive light stayed on for many minutes. My computer usually shuts down fast. I finally turned off power then rebooted. I got to Windows start up screen but then nothing and hard drive light was on. Tried safe-mode and it hung during loading drivers. Tried again a few times. Finally it got further and did a disk check on its own on my data drive - not main drive.

I then got into windows and everything seemed fine. I checked the event viewer and a few hours before this happened there were 5 red errors labeled atapi stating: "The driver detected a controller error on \Device\Ide\IdePort1." all time-stamped a few seconds of each other.

But I have no IDE Devices. Both my hard drives and my DVD drive are all SATA - I have no IDE devices.
Or does SATA use IDE device? If so, how do I tell which of my drives is port1?
What could this error mean? I did a disk check-now and found nothing wrong with either drive.

I was doing something inside my PC prior to this. Maybe I knocked a sata cable loose?

It is possible you knocked a SATA cable loose, it is also possible that one of your devices is going to die.
You should be able to check device manager under IDE ATA/ATAPI controllers (or something with controllers in it--dunno what win 7 says) and it will tell you what port it uses when you click on properties.

It does not list ports. It lists channels - are channels the same as ports?
And if so, I cannot tell which hard drive is on which channel because in device manager under IDE ATA/ATAPI controllers it just calls them "ATA Disk" in both channel 0 and channel 1. I guess I could disconnect the data hard drive and see which is left but is channel the same as port?
