Restrict Access to USB Flash Drive

There are 2 things that cause a USB flash disk storage media (and / or external hard disk) can not be accessed, the first due to accidentally access the disabled and the second, protected access. For the second reason will usually appear the message "The disk is write-protected". By editing the Windows registry, you can manage both.

Enable-Write Protected Disk

In these conditions, USB still readable, but can not be written or to store data. If you want to save the data will show a message like this:

To open access to the flash disk to copy data:

1. Open the registry editor windows: start menu -> Run -> type: regedit -> OK

2. Find the following key: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ StorageDevicePolicies

3. If at any WriteProtect the right panel, double click and fill in the section data value 0 or delete WriteProtect or can also delete the key StorageDevices. Then refresh (click F5).

4. Try out the USB Flash Disk, then plug it in again and repeat the copy data.
