Can't unlock Bitlocker Encrypted Drive

I have a Bitlocker encrypted external HDD without any OS installed in it. I plugged it to pc with usb then i unlocked my drive on Win10 with my password as usual then i was copying the data from my unlocked
Bitlocker encrypted drive to another non-encrypted drive. Then power cut suddenly. After that i can't access my Bitlocker encrypted drive anymore.

-When i try to unlock that drive from Windows Explorer pop-up says "Encryption on this drive is not compatible with your Windows. Try to unlock it with newer version of Windows." without password and recoverypassword/recoverykey
input options. But my Win10 is fully updated (1703)

-Tried Win7 popup came without asking any password "Failed to unlock the drive. No protector keys found in this drive."

-I also tried manage-bde -bitlockerdrive -protectors -get the output is "ERROR: No key protectors found". But drive seems like encrypted already.

-I tried repair-bde with 48 digits recovery password for recovering data to another HDD. Recovery done without any errors. Then did "chkdsk
outputdrive: /f" it says "File system is NTFS. The first NTFS boot sector is unreadable or corrupt. Reading second NTFS boot sector instead. Unable to determine volume version and state. CHKDSK aborted." The disk shown as RAW and i can't access it.

-After that i also tried thirdparty recovery tools for recovering data on the drive that created after repair-bde (decrypted RAW one). I recovered all my files without any corruption. But all of them shown
as RAW files and had randomized names without folder structure. Somehow repair-bde can't transfer folder structure. I tried thirdparty recovery tools on unaccessable Bitlocker encrypted drive. It listed all my files with correct file names and folders. So
folder structure on encrypted drive is not corrupted i think but i can't recover them because they are encrypted and i can't open any file. I need folder structure, my files are too dispersed. What is the solution ? Thanks.

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.
