Rescue USB sticks: fix sector errors once and for all

Quick overview:

Files are not displayed on the USB stick? Is there a problem with the display of the disk size? Or is the stick no longer recognized as a drive by Windows? Then you should check your USB stick for errors and repair it if necessary. Windows-Tweaks shows you how it works:

1. first transfer the USB Flash Drive Tester from Heise: http://download.cnet.com/USB-Flash-Drive-Tester/3000-2086_4-10810585.html.

2. plug in the flash drive, start the program and select the appropriate entry under "Select flash drive/card". For the most thorough test, click on "Select test type":

USB-01

Start by clicking on "Start test". Every sector error, no matter how small, is then displayed. Tip: If errors are found, the stick does not have to be disposed of immediately. "chkdsk" may be able to help: Open the command line and type "chkdsk G: /f /r /b" - where G in this case stands for the drive letter of the stick!

Founded Windows Tweaks as a teenager in 2001, his helpful PC tricks made it Germany's most visited Windows site (at the time Sandro looked like this). He then went on to write for international publications such as PC-Praxis, Computerbild, PCWorld in the USA, IMTEST.de and Hifi.de. Sandro's main job is as Global Product Marketing Lead and Consultant for various global tech companies, including Microsoft, AVG, Avast, Nero, TeamViewer, Swiss IT Security Group and now currently in the fintech sector for Gendigital. But he can't get rid of his passion and shares his tweaks here again. Privately, he enjoys traveling the world and loves Asia, especially Japan, Singapore and Korea, but also natural places like Iceland and the Nordics. You can reach Sandro via e-mail.
