2If FppExceptionFilter is on the stack, this parameter specifies the address of the exception record.
3If FppExceptionFilter is on the stack, this parameter specifies the address of the context record.

Description

The EXFAT_FILE_SYSTEM bug check has a value of 0x0000012C. This bug check indicates that a problem occurred in the Extended File Allocation Table (exFAT) file system.

Important

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

Cause

This bug check is caused by the file system as a last resort when its internal accounting is in an unsupportable state and to continue poses a large risk of data loss. The file system never causes this bug check when the on disk structures are corrupted, the disk sectors go bad, or a memory allocation fails. Bad sectors could lead to a bug check, for example, when a page fault occurs in kernel code or data and the memory manager cannot read the pages. However, for this bug check, the file system is not the cause.

Resolution

To debug this problem: Use the .cxr (Display Context Record) command together with Parameter 3, and then use kb (Display Stack Backtrace).
