If you are a Windows user, you might end up with this error message "semaphore timeout period has expired" along with an error code "0x80070079" when you are in the transferring process of files. So, why such errors occur, or what does the code imply? Like you, I am eager as well to know the secret and related concepts. So, why wait? Let's get in-depth on the 'semaphore timeout period has expired' error, its solutions, and tips on avoiding it in the future. 

Part 1: Overview of the semaphore timeout period has expired error

Introduce the causes, symptoms, knowledge of this issue. Not too long, maybe 2 or 3 paragraphs.

1. What is the ‘semaphore timeout period has expired error’ or 0x80070079?

This issue mainly occurs on Windows when you are transferring files between external drives or local networks. Usually, the 'semaphore timeout period has expired error' is a pop-up error message when a large file transfer occurs. The code, in turn, also implies when Windows is unable to retry the network connectivity within the given time or timeframe.

Another scenario that results in the semaphore timeout period has expired error is when you process some backup files or attempt to open a portable drive where the location becomes inaccessible.

2. Causes of the semaphore timeout period has expired error  

So, what causes the “semaphore timeout period has expired” error on Windows. Here is why it is.

• Corruption of the source or target’s file system.
• Existence of some harmful effects like RAID 6 failure on the drive.
• If the drive has undergone physical damage.
• Due to the damage to the network cable or USB.
• Due to the transfer for large files.
• Outdated driver or device drives.
• Prevention of file system access from antivirus program or network firewall.
• Networking issues like slow connection, improper or poor signals, and damaged adapters.
• Virus attacks, malware, improper application install, and unwanted temporary files.

3. Symptoms of the semaphore timeout period has expired error

Since you have walked through the causes for the 'semaphore timeout period has expired error,' here are symptoms or signs to detect precisely where the error has occurred.

• If the wireless network connectivity is low, and you are trying to copy large files, a semaphore timeout error raises, indicating poor network connectivity.
• When you have connected any flash or external drive to Windows via USB but couldn’t access the files leaving this error code, the error may be a sign of the corrupted drive or the adapter.
• If the particular drive has lost its communication with the rest of the system, semaphore timeout issues can pop up, indicating improper contact.
• If the memory space has a problem or the file path is long, you can develop the semaphore timeout error.

Part 2: Solutions to fix the semaphore timeout period has expired error

In this session, we have piled up solutions on how to fix the semaphore timeout period has expired error. Be relaxed and get to know them one by one.

Fix 1: Do a Clean Boot

To overcome some advanced Windows problems and troubleshoot them, you can initiate the "Clean Boot" mode. To execute this, press the hotkeys "Win+R" to get into the "Run" box, enter "MSConfig" that will lead you to the system configuration window of the system from where you can manage and disable the non-windows services.

Fix 2: Disable Firewall and Antivirus temporarily

During a file transfer from the source to the destination drive, the firewall and the antivirus program can block the process by popping up the semaphore timeout period has expired error. So, you can try disabling the functions for a certain period.

• To disable them temporarily, launch “Control Panel”.
• Choose the “Windows Defender Firewall” option to proceed.
• From the left panel options, tap the “Turn Windows Defender Firewall on or off” option.
• The following window disables the "Turn off Windows Defender Firewall" option under the customize settings section.  

Fix 3: Convert FAT32 to NTFS

As stated before, the transfer of a large file is another probable cause to generate the semaphore timeout period has expired error. To overcome this issue, when you transfer files from external drivers that use the FAT32 file system as the default type, you can try converting the FAT32 to NTFS format. You can use a third-party application for such conversion or try the in-built method too.

1. Right-click on the drive or local disk on Windows.
2. Choose the “Format” option and pick the “NTFS” option.
3. Tap the “Quick Format” button, and proceed with the file transfer again.

Fix 4: Update the Wireless driver Network Adapters

Suppose the "semaphore timeout period has expired" error is due to the failed backup attempt or network file transfer issues. In that case, you need to update the network adapters of the wireless driver. Follow the below steps to accomplish the job manually.

1. On the search box, enter “device manager” and click the first option.
2. Unfold the “Network Adapters” option by clicking the tilt triangle option. Right-click the network driver, and click the “Update Driver” option.

Fix 5: Run CHKDSK or System File Checker

You can run CHKDSK or a system file checker program to find the bad sectors or disk errors and repair the missing or corrupted file systems. If you aren't a tech-savvy person, this fix could be a little difficult as you need to enter the command prompt to fix the disk errors.

Part 3: Tips to avoid the semaphore timeout period has expired error

So, how to avoid the semaphore timeout period has expired error. You can follow the tips or tricks from this session to prevent the "semaphore timeout period has expired" error.

1. Fix or check for the bad sectors regularly: As the bad sectors are a probable cause of this issue, you should periodically check the conditions of the system driver along with the operating system Read/Write actions. To do so, you can run an administrative command prompt to find out the disk failures.
2. Keep an eye on the antivirus software: As third-party antivirus software might be a key for this timeout error, you can temporarily disable the application until you find the fundamental cause or fix the issue.
3. Check for any physical damage: To check any physical damage in the drive, USB, or network cable, check if there is fluctuation in the read/writes actions reverting to this semaphore timeout. While replacing the line is easy, if the damage is on the system hardware, opt for a professional data recovery expert with no second choice.
4. Importance to file size limit: There are times where the large files aren't transferred within the timeframe leading to the semaphore timeout period has expired error. For example, you cannot move FAT 32 file type more than 4 GB; hence compress it or look for an alternative.
5. Be updated: Semaphore timeout error raises when the drives are outdated or corrupted as well. This tip refers to the network drivers or networking hardware like connectors and network cards and the external drives like pen drive, which you need to update at times for proper communication.

The Bottom Line

Thus, we went through a few scenarios that can lead us to the 'semaphore timeout period has expired error.' We also discussed the root causes that can generate such a "semaphore timeout period has expired" error and potential ways to fix the semaphore timeout period has expired error. If you face this issue, it's time to become a system analyst and set it as data is always essential. However, don't try any DIY or other tricks, making matters worse!
