Help! The disk is write protected on Windows 10
Currently, USB drives (flash drives or pen drives) and SD cards (micro SD or memory cards) are widely used by computer users to store and transfer data. However, some users are confronted with "the media is write protected" in Windows 10. Here is one scenario:
“I used my Sandisk Cruizer Edge (32GB) on Windows 10 x64 and Mac Os X 10.7.x for a long time, but from some days I'm unable to add, change or delete files on both OS. I've checked on the Disk Management (under Windows) and I've noticed that the flash-pen is "Read Only" but I'm unable to change that status.
I can't format it, because I receive the error "The disk is write protected"... so, now I'm trying to change files status (I see that "Archive" is checked), but again in some files, I receive the same error...
It's very weird... even because I'm able to read everything on it... so the flash-pen works... I've tried to disable and uninstall it, but again, when Windows recognize it, present the same error... ”
Such an experience sounds annoying!
