I changed my registry on the wrong drive. Can i reverse this?

Hi man, thank you for coming back to me. This is what I did. I have since deleted the StorageDevicePolicies folder.

My brother is recovering the data, but it is taking forever. It's about 900GB And everything is scrambled. Is there no way I can reverse the effect on my hard drive?


Click start
then run regedit
go to this directory HKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\
if you can't find StorageDevicePolicies under control folder
then make some new one. Follow this steps:

step 1:
go to this directory HKEY_LOCAL_MACHINE\SYSTEM\Currentcontrolset\control\
again and right click control folder

step 2:
select new, then click key and rename the new key #1 folder into
StorageDevicePolicies

step 3:
right click StorageDevicePolicies folder and select new DWORD(32-bit) Value
for 32-bit Operating System and select new DWORD(64-bit) Value
for 64-bit Operating System

step 4:
rename dword newer folder into WriteProtect, then double click WriteProtect
and change the value data into 0 with hexadecimal base, Then close regedit

step 5:
open my computer and refresh it 5 times without do anything to your usb, and
properly eject your flash drive

step 6:
plug in your usb again into your computer and format it using exfat instead of fat32

Also I'm not sure what you mean with replacing the registry on my primary drive.

I basically wanted to format a USB flash drive, but didn't think that it might affect my hard drive that was still plugged in. So in essence I forced my important hard drive to be formatted. This sucks big time, since I don't have back-ups to most of my data.
