    This error may occur when system OS fails to build a connection or locate the source or target during file transfer. Although it is difficult to identify the exact cause, the error usually happens due to corrupt system files, faulty network adapter, weak signals, or corrupt disk drivers. Irrespective of the causes, this error means indicates that you are at the risk of losing your data.<\/p>

    1. Method 1: Update Network Drivers<\/strong><\/li>\n<\/ol>

      If the error occurred due to the faulty network adapters, the best way to fix the issue is to update the drivers. Follow the given steps to troubleshoot the problem:<\/p>

      a. Type devmgmt<\/strong> in the Windows search box and open Device Manager<\/strong>. (See Image 4)<\/strong><\/p>

      \n
      \"Open
      Image 4: Type ‘devmgmt’ in Windows Search Box to open Device Manager<\/figcaption><\/figure>\n<\/div>

      b. Double-click on Network Adapters<\/strong> and expand it.<\/p>

      c. Select the appropriate driver, right-click on it, and select Update Driver. (See Image 5)<\/strong><\/p>

      d. Select Search automatically for updated driver software<\/strong> on the next prompt.<\/p>

      e. Once the process is done, restart your system and check if the problem has been fixed.<\/p>

      Method 2: Disable Windows firewall temporarily<\/strong><\/p>

      It might be possible that a certain file transfer is blocked by the Windows Firewall. Try disabling the firewall protection temporarily to fix the error. Follow the below-mentioned steps:<\/p>

      a. Open Control Panel<\/strong> and click Windows Defender Firewall<\/strong>. (See Image 6)<\/strong><\/p>

      Wait till the process is completed and reboot your PC to check if the error is fixed.<\/p>

      Method 3: Run CHKDSK Command<\/strong><\/p>

      If the error is caused due to corrupt file system or bad sectors on the drive, you may run CHKDSK command. This command line utility may fix file system corruption, and allocate new sector for data located on bad sectors. Also, it may help you restore data from corrupt drive\/partition. Follow the given troubleshooting steps to fix the ‘Error 0x80070079’<\/strong>.<\/p>

      Caution<\/strong>
      Running CHKDSK command may lead to data loss as it marks the unreadable sectors as bad sectors. Hence, before performing this command, we recommend you to use a Windows data recovery software<\/a> to access and safely restore your data from the affected drive.<\/td><\/tr><\/tbody><\/table><\/figure>

      a. Open Command Prompt<\/em><\/strong> and select Run as Administrator.<\/strong><\/p>

      b. In the Command Prompt<\/em> window, type chkdsk \/f \/r x<\/strong>: and hit Enter<\/strong>. (See Image 9)<\/strong><\/p>

      X<\/em><\/strong> is the letter of a drive partition, \/f<\/em><\/strong> fixes errors, and \/r<\/em><\/strong> locates the bad sectors and reads information from them.<\/p>

      \n
      \"Run
      Image 9: Run “chkdsk \/f \/r x:” command in the Command Prompt window<\/figcaption><\/figure>\n<\/div>

      Note: <\/em><\/strong>If you are not able to transfer files to any volume of the drive, you need to run this command for every volume separately<\/em>.<\/p>

      Method 4: Perform a Clean Boot<\/strong><\/p>

      You may perform a clean boot to identify if any software\/app or program is conflicting and causing ‘Error 0x80070079’<\/strong>. Perform the following steps:<\/p>

      a. In the Windows Search box<\/em>, type msconfig<\/strong>, and open System Configurations<\/strong>. (See Image 10)<\/strong><\/p>

      \n
      \"Open
      Image 10: Type ‘msconfig’ in the Windows search box and open “System Configuration”<\/figcaption><\/figure>\n<\/div>

      b. Go to Services<\/strong> and choose Hide all Microsoft Services, <\/strong>given at the left bottom. (See Image 11)<\/strong><\/p>

      \n

      \"Disable
      Image 12: Select “Disable all” on window<\/figcaption><\/figure>\n<\/div>

      Apply the changes and restart your system.<\/p>

      Method 5: Convert Drive’s File System to NTFS<\/strong><\/p>

      This solution can work only if you want to copy data to a drive with a file system, which has a file size transfer limitation. For example, FAT32 cannot transfer a file larger than 4 GB. Transferring large-sized files is possible if the drive’s file system is formatted into NTFS<\/a>.<\/p>

      [Caution:<\/strong> Converting your drive’s file system to NTFS may fix the error but it will format the drive and erase all existing data. It this situation, we recommend using a data recovery tool <\/em>to retrieve formatted data after moving to NTFS file system.]<\/strong><\/p>

      Follow the given steps:<\/p>

      a. Navigate to This PC<\/strong>.<\/p>

      b. Right-click the target drive.<\/p>

      c. Click Format<\/strong> and select NTFS<\/strong> on the next prompt.<\/p>

      d. Select Quick format<\/strong> and wait till the process completes.<\/p>

      If none of the above methods fix the ‘Error 0x80070079: Semaphore Timeout Period Has Expired’<\/em><\/strong>, don’t perform any hit & trial method<\/strong>. Doing so may overwrite the data and you may end up losing any chance to restore it.<\/p>

      Can’t access my data due to Semaphore Timeout Period Has Expired error. What to do?<\/em><\/strong><\/p>

      Use the Best Windows Data Recovery Software<\/strong><\/h3>

      Even if you are not able to fix the error, the best you can do to save your data is to retrieve it from the affected drive and create a backup. To do so, you may use a DIY Windows Data Recovery software such as Stellar Data Recovery<\/a>. The software can retrieve data such as documents, email files, photos, videos that have become inaccessible due to Semaphore errors such as above. It supports multiple file formats and lets you recover data from formatted, corrupted, and even encrypted drives.<\/p>
