As there was some discussion of fakes. At your own risk and if you have access to Windows there are some good tools to low-level verify either for a fake or bad bits on USB/SD storage:
"FakeFlashTest" https://rmprepusb.com/tutorials/007-all-about-fake-sd-cards-and-usb-flash-drives/ "USB Flash Drive Tester" https://www.vconsole.com/download You might also want to try low-level formatting tools. The SD Association has a formatter for Win/Mac https://www.sdcard.org/downloads/formatter/ The download link on that page is currently broken, but this link works: https://www.sdcard.org/downloads/formatter/eula_windows/SDCardFormatterv5_WinEN.zip I have old formatting tools from Lexar and HP but I can't find their official sources. Be aware that low-level tools might render your item unusable until re-formatted with other low-level tools. I recommend you do read tests before write/format efforts. Years ago I bought a 1 TB USB stick for $10 CAD. At the time this was an impossible price for impossible storage so of course it was fake, but it amused me to test for and flag bad sectors as unusable to get it working. I got over 300 GB to verify as usable which was still incredible. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
