Rescue USB sticks: fix sector errors once and for all

Updated: December 4, 2024
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 the 90s. His helpful PC tricks made it Germany's most visited Windows site (back then this is what Sandro looked like). He then went on to write elsewhere, such as for PC-Praxis, Computer Bild and PCWorld in the USA. Microsoft also poached him from us. Now Sandro is back, finally sharing his tweaks here again. For a stress-free digital everyday life. You can reach Sandro via e-mail.
