Operating system: Win7 flagship version of SP1 X86room64

Removable hard disk: Western Digital 4TB, file system is exFAT

Failure phenomenon:

1. The computer is restarted during the read and write operation on the disk. After re-entering the operating system, the disk can only enter read-only mode.

2. Under the Windows system, the mobile hard disk is read-only and cannot be written. Follow the prompts to run the chkdsk fix.

3. No problem under the macOS system, the mobile hard disk can read and write.

Run chkdsk G: / f / r to detect the file system

Display: "unknown error 766f6c756d652e63 3f1", after the search engine query, because the file system is read-only mode, so chkdsk can not be repaired.

Cause of failure:

This issue occurs because of a Divide By Zero exception in the Chkdsk command.

This problem occurs because the exception is divided by zero in the chkdsk command.

Fault repair:

There are two ways:

Method 1: run the "disk tool" in macOS to give "first aid" to the mobile hard disk and repair the operating system failure.

Method 2: get the solution on the Microsoft technology platform: go to the page and get the Windows operating system repair patch.
