Atapi - Event ID:11 - The driver detected a controller error on \Device\Ide\IdePort0.

Hi Marc Hendrickx,

Welcome to Windows Vista Answers Forums!

This error may be occur  if you have 2 cd-roms on the same ide channel with incorrect jumper settings.

If the cd-rom jumpers were set as cable select then the IDE cable did not support it.  You may have to Configure the jumpers to master/slave option.

Check the system manufacturer manual to get in touch the the system manufacturer for information on how to do the changes in BIOS.

Note: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk

Hope this information is helpful.

Thanks for your response Praseetha. I only have 1 internal cd-rom on my laptop and I did not connect a second one. So I doubt it if the error is because of 2 cd-roms. Any other suggestions?

Hello
      I'm experiencing the same errors, but only after Windows 7 was installed.  I had previously dual-booted XP and Vista.  Neither OS reported these errors.  I wiped out XP, and now dual-boot Win & and Vista.  Win 7 reports these errors and again, Vista does not.
      This does not appear to be a hardware issue, but a driver issue.

Thanks

Greetings,

I am having the same errors and only after upgrading to Win 7.  I only have the one OS on my laptop with only one internal cd/dvd drive.  However, I am getting a blue screen shortly after the errors (7 total logged) and an additional error (NTFS), "The system failed to flush data to the transaction log. Corruption may occur."

I have turned off the auto restart and will try to get additional information. 

Thanks.

Hi, All.
I just installed a Windows 7 Pro (Japanese) on a new Hitachi 1TB hardisk in my Dell Dimension 8400. It installed easily and works fine, except performance does seem very slow at times. When I checked the System error log, I see there have been dozens of disk errors (below) occuring each day. Does anyone have any suggestions to eliminate these errors?
Many thanks in advance!

Did anyone get a fix for this issue?

I am also having the same issue. This is a new build running win 7 64 bit. Event log is full of atapi errors...performance seems to be degraded at times.

I had this problem too. Solved it by re-installing ATA channels 0 and 1. Go to device manager--> IDE ATA\ATAPI Controllers--> and delete ATA channel0 (2x) and ATA channel1 (2x). Reboot and check event logs for errors.

Hope this helps.

good luck

Thanks, Ben.

Bill, yes the ata channels must be visible after rebooting.
But my solution appeared not to be the right one. A couple of days after posting the message above my problems re-started. System hang, no proper reboots, etc.
It now appers to be a problem with the SATA controller on my motherboard. I switched my harddisk connection from SATA controller 0 to controller 1 and system is running ok.
So the event 11 atapi error:

The driver detected a controller error on \Device\Ide\IdePort0.

also occures when using bad SATA controllers.
