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.
