Hello DoOom,

The information you linked to was made before Windows 8 came out. There is no reason the pen drive would not work in Windows 8.

If it is working in other computers, then just the driver is most likely corrupted on your operating system. Try these steps to troubleshoot the Pen Drive. Confirm that the port on the computer is not bad. Choose a different port to insert the drive. Next…

Part 1: Make sure that the drive has a drive letter assigned in Disk Management.

  • Open Computer Management by right clicking on Computer and clicking Manage.
  • Click on Disk Management. Give it a moment to open the view of the drives installed. Look for a drive that does not have an assigned drive letter and is not labeled as System Reserved.Note: System reserved drives are reserved by Windows and will not allow you to assign a letter.
  • Right-click the unlabeled drive and click Change drive letter and paths. Click Add and then click OK to select the first available drive letter.

If the Change drive letter and paths… option is not available, make sure that the drive is Online.
If the drive is Offline, right click the disk number and click Online.

Part 2: If the drive has a letter assigned and it still does not work, uninstall the driver.

You can safely remove any usb drivers that are not in use (hidden drivers). Devices that get plugged in later will simply reinstall its needed driver again.

  • Remove the pen drive from the computer if it’s attached.
  • Right click Computer and click on Properties. In the System window on the left side, click on Advanced System Properties.
  • Choose the Advanced tab and click on Environment Variables… button at the bottom.
  • Under System Variables, click on the New… button.  Type this in the box that pops up...
    Variable Name: devmgr_show_nonpresent_devices

    Variable Value: 1

  • Click OK on all the open windows to close them out.
  • Go to Computer Management again and click on Device Manager. Go to View at the top of the window and click on Show Hidden Devices.
  • Click on the drop down arrow for Universal Serial Bus Controllers to open the list.
  • Look for any USB Mass Storage Device that is hidden (greyed out) and delete it. There may be several and it’s ok to delete all those hidden USB Mass Storage Devices.


When you connect the pen drive to the computer again, give it a minute to reinstall the driver.

 

 

Let me kow if there is anything else I can do.

Good luck.
