Windows 10: Weird Bitlocker Problem - unlock dialogue not appearing

I have two identical 32gb Sandisk USB 3 thumb drives, each divided into two partitions with the second on each bitlocked, and the same problem with each. In summary the unlock passord dialogue is not appearing on my Desktop PC so I cannot unlock the drive/partition.

It happens annoying irregularity, and once it has happened the unlock dialogue never appears again even after reboots. BUT I can succcessfully unlock the same thumb drive partition on my laptop. And it can happen to either drive - the only solution I have found so far being to reformat the partition, bitlock and wait for it to fail again.

Once the unlock dialogue fails to start, DIsk Management on my Desktop PC shows the partition to be Unknown (BitLocker Encrypted) Healthy (Logical Drive), and not surprisingly I cannot add a drive letter. On my laptop once unlocked it shows as FAT32.

I have also found that if I dismiss the unlock dialogue without unlocking the drive, that causes the same problem every time, not irregularly.

Can anyone help please as it is driving me CRAZY

HELP: Automatic BitLocker Unlock.

Thank you sir, ill try your solution.

Windows Auto unlock ONLY works in case you have Bitlocker on your system drive, because if your system drive is not encrypted auto unlocking other drives means loss of security.
But in my case my system drive is Encrypted with hardware encryption that i password unlock during boot. So auto unlocking Bitlocker drives will do fine for me.

 

HELP: Automatic BitLocker Unlock.

Please help,
Looking for a way( script or maybe some unknown windows command or registry hack) to automatically unlock a non OS BitLocker encrypted drive on Log-In.

My situation: Right now my OS SSD Samsung 840 Evo has a boot password, its not Bios option nor windows eDrive but the third one, the one you need 3rd party software to activate it, had to purchase EMBASSY Security Center to do it.
No issues here, the OS drive is locked and encrypted.

One of My HDD Drives is encrypted with Bitlocker, so every time my PC is booted, I need to enter windows log-in password and then open my computer and enter another password to unlock the drive.
Whats worse is that unlike the SSD that needs unlock password only after full shutdown the Bitlocker needs it every log-in.

Windows has an option to Automaticlly unlock all BitLocker drives on boot, BUT the issue here is that this official option only works if your OS drive is also BitLocker encrypted and then log-in password unlocks everything.

Im looking for maybe a windows Script or some Hidden command to automatically unlock the BitLocker drive.

Even if it Sounds insecure like having the actual password somewhere in the registry, text file or script I dont care because the OS drive is encrypted and passworded.
Also I have a TPM chip I can encrypt any file/folder so even if file is copied from my PC when its fully unlocked the files wont be readable anywhere unless unencrypted before.

If its important im on 8.1 pro 64bit

P.S. If there is no solution for my problem then my only choice is when windows 10 comes out to do a clean install on another Samsung 840 Evo that was previously cleared and eDrive option enabled


Thanks in advance.
