DATA_BUS_ERROR

The DATA_BUS_ERROR bug check has a value of 0x0000002E. This typically indicates that a parity error in system memory has been detected.

Important

This topic is for programmers. If you are a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.

DATA_BUS_ERROR Parameters

Parameter Description

1

Virtual address that caused the fault

2

Physical address that caused the fault

3

Processor status register (PSR)

4

Faulting instruction register (FIR)

Cause

This error is almost always caused by a hardware problem -- a configuration issue, defective hardware, or incompatible hardware.

The most common hardware problems that can cause this error are defective RAM, Level 2 (L2) RAM cache errors, or video RAM errors. Hard disk corruption can also cause this error.

This bug check can also be caused when a device driver attempts to access an address in the 0x8xxxxxxx range that does not exist (in other words, that does not have a physical address mapping).

Resolution

Resolving a hardware problem: If hardware has recently been added to the system, remove it to see if the error recurs.

If existing hardware has failed, remove or replace the faulty component. You should run hardware diagnostics supplied by the system manufacturer to determine which hardware component has failed. For details on these procedures, see the owner's manual for your computer. Check that all adapter cards in the computer are properly seated. Use an ink eraser or an electrical contact treatment, available at electronics supply stores, to ensure that adapter card contacts are clean.

If the problem occurs on a newly installed system, check the availability of updates for the BIOS, the SCSI controller or network cards. Updates of this kind are typically available on the Web site or the bulletin board system (BBS) of the hardware manufacturer.

If the error occurs after installing a new or updated device driver, the driver should be removed or replaced. If, under this circumstance, the error occurs during startup and the system partition is formatted with NTFS, you might be able to use Safe Mode to rename or delete the faulty driver.

If the driver is used as part of the system startup process in Safe Mode, you need to start the computer using the Recovery Console in order to access the file.

For additional error messages that might help pinpoint the device or driver that is causing the error, check the System Log in Event Viewer. Disabling memory caching or shadowing in the BIOS might also resolve this error. In addition, check the system for viruses, using any up-to-date commercial virus scanning software that examines the Master Boot Record of the hard disk. All Windows file systems can be infected by viruses.

Resolving a hard disk corruption problem: Run Chkdsk /f /r on the system partition. You must restart the system before the disk scan begins. If you cannot start the system due to the error, use the Recovery Console and run Chkdsk /r.

Warning   If your system partition is formatted with the file allocation table (FAT) file system, the long filenames used by Windows can be damaged if Scandisk or another Microsoft MS-DOS-based hard disk tool is used to verify the integrity of your hard disk from MS-DOS. Always use the version of Chkdsk that matches your Windows version.

About “What is” service

Many of users are faced with the problem of interpreting errors that occur during the work of operating systems. In some cases, the operating system reports that an error has occurred and displays only an integer error code value. Often it is difficult to even roughly understand the cause of the error from the information given out. Our “what is” service contains a database of errors in Windows, Linux, Macos and Solaris operating systems. The database contains tens of thousands of values. In most cases, the online service will be able to help with the definition of the short name of the error and its detailed description.

Categories

Current version of service supports following types of error and status codes:

NTSTATUSMany kernel-mode standard driver routines and driver support routines use the NTSTATUS type for return values. Additionally, drivers provide an NTSTATUS-typed value in an IRP’s IO_STATUS_BLOCK structure when completing IRPs. The NTSTATUS type is defined in Ntdef.h, and system-supplied status codes are defined in Ntstatus.h.
Win32 errorWin32 error codes MUST be in the range 0x0000 to 0xFFFF, although Win32 error codes can be used both in 16-bit fields (such as within the HRESULT type specified in section 2.1) as well as 32-bit fields. Most values also have a default message defined, which can be used to map the value to a human-readable text message; when this is done, the Win32 error code is also known as a message identifier.
HRESULTHRESULT is a data type used in Windows operating systems, and the earlier IBM/Microsoft OS/2 operating system, to represent error conditions, and warning conditions.
The original purpose of HRESULTs was to formally lay out ranges of error codes for both public and Microsoft internal use in order to prevent collisions between error codes in different subsystems of the OS/2 operating system.
HRESULTs are numerical error codes. Various bits within an HRESULT encode information about the nature of the error code, and where it came from.
HRESULT error codes are most commonly encountered in COM programming, where they form the basis for a standardized COM error handling convention.
HTTP Status CodeHypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client’s request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP. The first digit of the status code specifies one of five standard classes of responses. The message phrases shown are typical, but any human-readable alternative may be provided.
errnoInteger value, which is returned by system calls and some library functions in the event of an error to indicate what went wrong. errno is defined by the ISO C standard to be a modifiable lvalue of type int, and must not be explicitly declared; errno may be a macro. errno is thread-local; setting it in one thread does not affect its value in any other thread.
Kern ReturnApple Kernel return codes.
Ipp StatusThe IppStatus constant enumerates the status values returned by the Intel IPP functions, indicating
whether the operation is error-free.

Source code

The service is based on the open source library AllStat. Its sources are available on our git server. We will be grateful for your participation in the finalization of the library and ideas for the development of the service. You can also download ErrorLookup libraries and utilities from our site.
