Suddenly, my PC "WriteProtect" any & every USB Flash or external HardDisk I plug into it.
I've Googled the problem & tried the only 2 solutions I found. None worked.
- regedit : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
- CMD : diskpart, list disk, etc.
Some of the flashes I tried would work fine on other PCs ie: not write protected!!!
If I plug them again into my PC, they become "WriteProtect"!!!
My OS is Windows 8.1
Please help. Thank you.
