Read-only, also known as write-protected, is a file system permission that only allows a user to read or copy stored data but not write new information or edit the existing data. You can set the read-only to the entire disk to prevent accidental formatting.

In this gearupwindows post, we will show the different ways to fix the read-only to a disk. This happens to HDDs a lot, and it’s also commonly seen on removable disks like SD memory cards and USB flash drives. These troubleshooting methods effectively change a hard drive, USB flash drive, pen drive, or SD card from ready only to read-write.
