How to Remove Write Protection on a Toshiba Transmemory Flash Drive
Toshiba's Transmemory line of flash drives are similar to an external hard drive in that they provide storage space for saving your photos or MP3s outside your computer. If you don't want other people to have the ability to change your files, you may want to turn on the write protection option. If you need to regain ability to modify the files, you need to remove write protection either physically or by changing options in Windows 7, Windows Vista or Windows XP.
Physical Protection and Read Only Feature
Locate the small, plastic write protect switch positioned on the side edge of the Toshiba Transmemory drive. Slide the switch down into the unlocked position to turn off the Toshiba's physical write protect option.
Plug the Toshiba Transmemory drive into a USB port on your computer. Select the "Open a folder" link in the "AutoPlay" prompt.
Try changing one of the files saved on the Toshiba drive to see if the write protection feature remains enabled. Right-click the file and select "Properties."
Click the file tab labeled "Security." Select the "Full Control" option underneath the "Allow" heading. Navigate to the "General" tab. Click "Read Only" if the box is currently checked, or leave the box blank if it is currently un-checked.
Select "OK" and try modifying the file again.
Navigate to the Windows "Start" menu and type "Regedit" in the "Search" box. Select the registry editor's icon and click the "HKEY_LOCAL_MACHINE" folder.
Select the folders named "SYSTEM," "CurrrentControlSet," "Control" and "StorageDevicePolicies." Right-click the "WriteProtect" entry and select the "Modify" option. Delete whatever number is listed in the text box and type "0."
Click "OK." Back out to the folder path "HKEY_LOCAL_MACHINE\SYSTEM." Open the first sub-folder named "ControlSet001." Repeat the process of modifying the "WriteProtect" file to "0."
Repeat the process with the "ControlSet002" folder and any other folders using the same name scheme, such as "ControlSet003." Restart the computer and try modifying the file again.
Format the Transmemory Drive
Access the "Start" menu and choose "Computer." Locate the entry for the Toshiba Transmemory flash drive.
Right-click the entry for the Toshiba Transmemory drive and choose "Format." Remove the check mark from the "Quick Format" button at the bottom of the window if it is checked.
Click "Start" to erase all the data on the Transmemory drive and return it to its original factory settings.
Tips & Warnings
- Your flash drive may include the "Transmemory Secure" software. If any files on the drive are protected by the software, double-click the "Transmemory Secure" icon in the flash drive's window. Type the password in the text box and click "OK" to unlock the files.
- Depending on your computer's settings, the "StorageDevicePolicies" folder may not already be created. Right-click the "Control" folder and choose "New" and "Key." Enter "StorageDevicePolicies" and hit "Enter." Right-click the empty area of the folder and select "New" and "DWORD." Type "WriteProtect" and hit "Enter." Modify the entry's value to "0" normally.
- To change the file's security properties or edit the registry, you need to be logged in to the operating system with an administrative account.
