Windows 10: Unlocked Bitlocker but drive is still Write Protected - Urgent Help Required

Hello,


I have a Customer with Windows 10 I believe 1909 computer that has been bitlockered. Unfortunately due to updates I think my customer is no longer able to log in to the computer, after entering their password, it just sits there logging them in, so I need to do some troubleshooting.


Unfortunately the customer is on the other side of the world to me, so it is a bit time consuming, however I was able to talk them through booting to Windows PE and unlocking the Hard Drive with the AD stored Bitlocker Password. We are now able to see all the files on the hard drive.


At this stage I should be able to manipulate files on the hard drive to do some trouble shooting, any commands we run on the computer to change anything on the hard drive is met with "The Media is Write Protected"


We have tried:

* Disabling the protectors on the disk: manage-bde -protectors -disable c:

* Deleting the protectors: manage-bde -protectors delete c:

* Turning off Bitlocker: mangae-bde -off c:

* Changing the ReadOnly attribute in Diskpart


I am assuming this has something to do with a policy being set that disables writing to a disk that is not protected, but I cannot get to the registry of the computer to change that.


Please throw as many suggestions as you feel like at me. What can I try next?

:)

Bitlocker making removable media Write Protected

I work for a company who handles secure data. We use bitlocker to encrypt the drives on all company machines, as well as all removable storage devices (USB Flash drives, External Hard Drives, ETC.). This works seamlessly for all built in storage, but for
removable media, it is forcing write protection on the drives after encryption, even after the drive is unlocked using the Bitlocker passcode. We still want to maintain the enforcement of encrypting anything that may contain private company data, including
all removable storage devices, but want to still be able to write to them after they are encrypted. Is this normal? Is there any way to have all removable storage devices encrypted but disable write protection once they are unlocked?

Thanks!
