Intermittent hangs. Event log shows event 11 atapi: The driver detected a controller error on \Device\Ide\IdePort1. How do I find this device? Is this probably a hardware problem?
I am investigating intermittent hangs, where my cursor becomes an hourglass and the system will not even respond to ctrl-alt-del. In the event log, I find
Event 11 atapi : The driver detected a controller error on \Device\Ide\IdePort1.
How do i determine which physical device(s) this is associated with? Does this indicate a hardware problem, or might driver or firmware be the source?The system has been running fine for a couple years. I am not aware of any software changes that have occurred recently, though I did have to forcibly remove and reinstall iTunes a little while ago.
I have run SMART checks on all drives and run some diagnostics. I ran chkdsk on the one that I thought was the culprit, but no errors.
Just in case it was a memory-related hang, I tried to use the microsoft memory diagnostic on floppy, but it wouldn't write to the floppy (even though I could format it and copy files freely).

Hi
Go into your setup and look at what drive is adressed at each port; 1,2,3,4....
Then go to Device Manager and look how many SATA controller you have and how many ports for each, then start count from 0 for IdePort0, 1, 2, etc. for each SATA controller, so if you got 4 ports for each SATA controler, here it is how you got to count:
drive 1 - IdePort0, drive 2 - IdePort1, drive 3 - IdePort2 and drive 4 - IdePort3 in sequence
I hope it helps
I concur with the comments made by Laborn, I have also been wrestling with this same problem for several days now without any fruitful outcome.
Admittedly I haven't tried all the suggestions mooted in this thread, but from what I've seen non have been conclusively successful.
My only conclusion being that the Event Log is not really 'Fit for Purpose' in that its not providing confidence to users with an accurate assessment of the real root cause to this problem !
Is it a problem with the Drive ? Or you name it ?
The only viable workaround I can find for this problem is to leave my PC in 'Sleep Mode'!
At least this gives me the immediate access I used to enjoy, not withstanding the occasional hangs I still get when online.
This thread is 7 years old and still, no one has clarified this confusing, horribly written "solution" to what should be a really simple task of determining the physical drive that corresponds with any given ideport.
"Go into your setup" is essentially nonsensical. What setup? That's not a Windows term.
"Then go to Device Manager and look how many SATA controller you have and how many ports for each..."
How many ports for each? What does this even mean. There are no ports listed in Device manager. Only channels. Again. Nonsense that doesn't even try to conform to MS terminology. The rest of his comment is rendered useless by this same conflation of terms.
In devise manager, on my W7 Pro 64 OS, I see, listed under IDE ATA/ATAPI controllers, I see this:
ATA Channel 0
ATA Channel 1
ATA Channel 2
ATA Channel 3
ATA Channel 4
ATA Channel 5
Opening the Properties/Details for each channel and scrolling through all the properties, the words "port" or "ideport" are not mentioned once.
It is 2016, and I have spent 2 days now trying to find the answer that was posed in this thread:
How do i determine which physical device(s) this [Error 11 Ideport] is associated with?
Or to put it more concisely: How can one determine which physical drive corresponds to which ideport without having to open the computer case?
I can't believe there isn't a simple utility app that performs this function. Or a simple, straightforward method.
While this error can indeed mean anything, like faulty hardware - it is indeed VERY OFTEN related to bad, cheap IDE/Sata Cables. I had this error multiple times already and i just again finished exchanging SATA cables on a PC to fix the errors.
Main sources of the Event 11 Atapi error are
*) Cheap SATA cables, usually those which come with your motherboard
*) Old SATA cables which are used in a PC for some years already
*) Low quality SATA cables
The error can appear "all of a sudden" after months or years - and there is no visible indication that something is wrong, all cable connections look fine. The problem is that SATA cables and connectors have a very low life-span, unplugging and re-plugging them a few times could already be reason enough to replace the cables.
( The error can cause lock-ups and delays in working with your PC since the PC tries to access drives and encounters errors, or your PC/Windows can also switch your IDE/SATA controller from DMA mode to the slower PIO mode which means that your drives will work less efficient than using DMA mode! Also..the indication that there is an error on "Atapi" does not necessarily mean that the connection to your CD/DVD drive is affected. I just did some troubleshooting assuming the same thing - just to find out it was actually the SATA connection on my second hard drive. )
Solution: Get high quality SATA cables with metal latches. Replace ALL and ANY of the Sata cables, especially if you use those which came with your motherboard. I had this error multiple times already on various computers affecting various drives, burners and hard drives. Each and any time replacing the cables fixed the problem.

Maybe this information can help:
Computer Management -> Disk Management -> Right click on "Disk0" (Disk1, Disk2 etc) -> Properties -> Details -> Property = Physical Device Object name
\Device\Ide\IdeDeviceP2T0L0-7 - this is my first HDD (Disk0)
"IdeDeviceP2" - maybe is "\Device\Ide\IdePort2"
I have 2 IDE DVD-ROM and 5 SATA HDD. DVD-ROM connect to PATA port and same P*, but different T* in IdeDevice****.
All SATA disk have different P*.
But if one HDD1 junk to folder on HDD2 and have errors, in error message show port for HDD2 !!! Add drive letter to all HDD (maybe not all partitions) and EventViewer show correct "IdePort"
