USB Write Protection Software: Enable / Disable Writing or Lock USB Drives
In Floppy disks, there used to be a write protection button which prevented writing or modifying files on disk. However, USB Pendrives or micro USB cards don’t come with any button or switch. So, here is how you can enable or disable write protection on USB using software.
Why Enable Write Protection on USB Drive
If you are giving your Pendrive to somebody and don’t want them to make changes or delete anything, write protection is the best solution. They will be able to read content, access and copy the files from pendrive but won’t able to paste anything or delete any file.
It also helps when you aren’t sure about a public / shared computer about its malicious behavior. Especially in school/institutes where most of the computers are infected. When you insert your pen drive in such places, it also gets infected. This may result in corrupting of files on drive and in turn may spread virus on your computer too.
So, if write protection is enabled, no virus will be able to inject anything on drive.
How To Enable/Disable Write Protection on USB Drive
