Perform a Clean Boot

Perform a clean boot in order to make sure that there isn’t a file/program conflict causing this error. With a clean boot, you’ll be able to disable startup programs and non-windows services that are unnecessary. Don’t worry about your data – it will remain secure and safe throughout the operation. Here’s how to do it.

Hit Windows Key + R to start the Run box. In the Open: field, enter “msconfig”. Hit Enter. You’ll see the System Configuration window open. Navigate to the Service tab. Check the box in front of Hide all Microsoft services and then select Disable all. Now, restart your device.

NTFS Instead of FAT32

Performing a transfer of large files can be done only if the drivers are formatted as NTFS. This is especially true if you’re using an USB external drive. Converting FAT32 to NTFS should help here.

Find the driver in question and right-click it. Then, select Format from the list the pops up. In the next window, you’ll get to choose between FAT32 and NTFS. Select NTFS. Click Quick Format to commence formatting and wait until the process is completed.

Remove HDD Entries

To do this, navigate to the Universal Serial Bus controllers category and right-click any of the old HDD entries. Then, select Disable Device. Do this for all old HDD entries.

Disable Firewall and Antivirus

Your antivirus program or Windows Firewall itself can mislabel a file as a threat. If this happens during the transfer, you may receive the semaphore timeout period has expired 0x80070079 error. Therefore, try disabling your computer’s security measures and retry the process. Bear in mind that you should be absolutely certain that the file in question isn’t a potential virus.

To disable Windows Firewall, press Win + X or right-click the Start button. Then, select Control Panel. Once the Control Panel opens, find the firewall manually or type “windows firewall” in the search box. Follow the instructions to disable the firewall protection.

Disabling your antivirus is different. Each antivirus has its own interface. Your best bet would be finding how to turn it off on Google.

Update the Drivers for Your Network Adapter

Run the System File Checker (SFC) and Deployment Image Servicing Scans (DISM)

If the semaphore error is a result of corrupt, damaged, or missing files, an SFC or a DISM check should take care of it.
