Troubleshooting Stop Messages in Visual C#

Generation QR Code ISO/IEC18004 in Visual C# Troubleshooting Stop Messages

0xC0000185, or STATUS_IO_DEVICE_ERROR, indicates improper termination, defective storage controller hardware, defective disk cabling, or two devices attempting to use the same resources .

The following suggestions are specific to Stop 0x7A errors . For additional troubleshooting suggestions that apply to all Stop errors, see the section titled Stop Message Checklist later in this chapter .

Stop 0x7A can be caused by bad sectors in the virtual memory paging file, disk controller error, virus infection, or memory hardware problems . In extremely rare cases, depleted nonpaged pool resources can cause this error . If the first and third parameters are zero, the stack signature in the kernel stack is missing, an error typically caused by defective hardware . If the I/O status is 0xC0000185 and the paging file is on a SCSI disk, check for cabling and termination issues . An I/O status code of 0xC000009C or 0xC000016A indicates that the requested data could not be found . You can try to correct this by restarting the computer . If a problem with disk integrity exists, Autochk a program that attempts to mark bad disk sectors as defective so that they are not used in the future starts automatically . If Autochk fails to run, you can manually perform the integrity check yourself by following the instructions to run ChkDsk provided in the section titled Stop 0x24 or NTFS_FILE_SYSTEM earlier in this chapter . For more information about ChkDsk, see 30 . Another cause of Stop 0x7A messages is defective, malfunctioning, or failed memory hardware, such as memory modules, L2 SRAM cache, or video adapter RAM . If you added new hardware recently, remove and replace the hardware to determine whether it is causing or contributing to the problem . Run Windows Memory Diagnostics as described in 30 to determine whether the feature has failed . Check the hardware manufacturer s Web site for updates to disk adapter firmware or drivers that improve compatibility . Verify that your disks and controller support the same set of advanced features, such as higher transfer rates . If necessary, select a slower transfer rate if an update is not yet available . Consult your hardware or device documentation for more information . The problem might also be due to cracks, scratched traces, or defective features on the motherboard . If all else fails, take the system motherboard to a repair facility for diagnostic testing . Problems that cause Stop 0x7A messages can also cause Stop 0x77 messages . For more information about Stop 0x77 messages, see the section titled Stop 0x77 or KERNEL_STACK_INPAGE_ERROR earlier in this chapter .

The Stop 0x7B message indicates that Windows has lost access to the system partition or boot volume during the startup process . Installing incorrect device drivers when installing or upgrading storage adapter hardware typically causes Stop 0x7B errors . Stop 0x7B errors could also indicate a possible virus infection .

This Stop message has four parameters:

1. 2. 3. 4.

The address of a Unicode string data structure representing the Advanced RISC Computing (ARC) specification name of the device at which you attempted startup . Pointer to ARC name string in memory . This value is 0x00 (zero) . This value is 0x00 (zero) .

The first parameter typically contains two separate pieces of data . For example, if the parameter is 0x00800020, 0x0020 is the actual length of the Unicode string and 0x0080 is the maximum ARC name string length . The next parameter contains the address of the buffer . This address is in system space, so the high-order bit is set . If the file system is unable to mount the boot device or simply does not recognize the data on the boot device as a file system structure, the following parameter definition applies:

1. 2. 3. 4.

The address of the device object that could not be mounted . Error code value or 0x00 (zero) . This value is 0x00 (zero) . This value is 0x00 (zero) .

The value of the first parameter determines whether the parameter is a pointer to an ARC name string (ARC names are a generic method of identifying devices within the ARC environment) or a device object because a Unicode string never has an odd number of bytes, and a device object always has a Type code of 0003 . The second parameter is very important, because it can indicate whether the Stop 0x7B message was caused by file system issues or problems with storage hardware and drivers . Values of 0xC000034 or 0xC000000E typically indicate:

Disks or storage controllers that are failing, defective, or improperly configured . Storage-related drivers or programs (tape management software, for example) that are not fully compatible with Windows .
