HDD GURU FORUMS

Hi,
I have a 256G usb key was working few month ago even very slow, can't save files now.
there are only folder names left after paste, why?
Thanks for help.

perhaps it's a fake and the FS became corrupt after address overflow?

If it became slower over time it may be the NAND being bad and went read only state while doing that last copy.

Fake UFD and memory card write fast to non existent NAND often.
