Windows 7: Event ID 11 ATAPI

10 Nov 2010   #1

Windows 7 x64
Event ID 11 ATAPI

I posted this in another thread too, but I think this might be related to some drivers maybe an expert on device/drivers can answers me here too.

I got an issue, wich I already solved partially, but I need input to localize the real source of the problem.

I need an input from advanced and experienced users with theses kind of problems if possible.

I realized this morning that my windows start screen took 3 minutes to load up for the last 2 days. (usually takes 15 second) I opened the even viewer and started to see lot of

event ID 7026
The following boot-start or system-start driver(s) failed to load:


Event ID 15
The device, \Device\CdRom0, is not ready for access yet.

In the bios, the device was detected but the name displaying was kind of random character that I cannot reproduce with my keyboard. (or I do not know how) Then I lost my second HDD who would not be detected correctly, but came back to normal after a normal reboot.

After, I switched the device to another sata port. Now the Bios does not recognize the device DVD-ROM/Cd-ROM...however, windows does and the device work properly again and seen and detected by windows 7 in every services. (before I could not even see it in the device manager)

Also, after finding that everything works, I reviewed again the event viewer and found this strange and alarming event :

Evend ID : 11 ATAPI
The driver detected a controller error on \Device\Ide\IdePort4.

My question is, w** ? what about my bios, my sata reading, is something wrong ? should I try again the ''defective'' sata port ?

sorry for the brutal ending

Hello ManOwar,

I also posted this in a couple of other threads, but If you have an Intel chipset I solved my ATAPI errors promblem by installing the SATA AHCI drivers included in the Intel ""RST and AHCI Driver and GUI" file package. It can be found by a search here: Intel Download Center . The SATA AHCI driver is located in the \Drivers\f6flpy-x64 or \f6flpy-x86 folders . Use device manager to update. After updating restart computer. When restarted Windows will reinstall drivers for the harddrive(s). Another restart is required.

I have not had an error since I installed the new driver about two weeks ago and my computer is working smoother than ever.

Laurus12's fix above worked for us. We were getting hundreds of the Atapi error messages during testing. After installing the RST drivers he references, ALL error messages are now gone. THANK YOU!
