Windows 7: How to identify device in error?

How to identify device in error?

I am seeing Event 11 errors in my system log. How can I determine which device this error refers to? In this case, how do I determine what "Ide\IdePort5" refers to?

- ATAPI (AT Attachment Packet Interface) is an interface between your computer and attached CD-ROM drives and tape backup drives.

Most of today's PC computers use the standard Integrated Drive Electronics (IDE) interface to address hard disk drives. ATAPI provides the additional commands needed for controlling a CD-ROM player or tape backup so that your computer can use the IDE interface and controllers to control these relatively newer device types.
ATAPI is part of the Enhanced IDE

How many do you have?

See my system specs. I have one SATA CD/DVD drive and no tape drives. There are five SATA hard drives spinning, one of which is not activated. On USB there is one Sandisk CF reader with no card in it. I also have virtual drives for mounting ISOs, but nothing is mounted at this time. The errors are recent. I've been running Win7 for about a week and just started seeing the errors.

Earlier versions of my system specs showed RAID 0 for two drives. I had to break the RAID array and change the Intel SATA storage from RAID to AHCI to eliminate iaStor errors.

My question is: how do I determine which physical device \Device\Ide\IdePort5 refers to?

Reading would be one way of telling.

It's the optical drive.

I am still interested in knowing the answer, in general, of how to know which physical device a unix-like \device name refers to. While that information may not be needed to interpret this error, it may be useful in the future.

This utility allows you to browse the Object Manager namespace, including \devices: WinObj

Not all devices map directly to hardware.

Thank you. WinObj is very interesting.

Windows 7 Ultimate x64

I'm having this same problem and can't figure out the cause. Whenever im doing random stuff my computer will freeze for about 30 seconds or so and when i check the event viewer i get the following error:

Error Source: atapi
Event ID" 11
The Device detected a controller error on \Device\Ide\IdePort5

I thought it was my cd-rom drive so i replaced an SATA cd-rom with an ide cd-rom i had laying around. Figured this would check the cd-rom, the cables, and the sata connection on the mobo.

Then i checked my hard drives. i removed all drives and put in a single new sata drive with a clean installation of windows 7 and am still getting this problem. I've also swapped the SATA cables out with new ones as well.

Anyone have any ideas as to what the problem may be?

From the 30 seconds, I'm guessing it is trying to access the drive, and then timing out.

Does it still happen if you have a disk in (or out if you currently have)?

Check your config like in my screenshot, should explain it.
