I have 2 storage hdd encrypted w/ bitlocker, in addition to the encrypted OS volume C:.

I activated auto unlock expecting the storage volumes to automatically unlock with the unlocking of C: (I enter the psw during boot since I don't have TPM). However they stay locked until I open them and manually enter their psw.

Looked everywhere on the internet for solutions but the problem is still here, so I'm posting asking for help.

Things to know:
- storage volumes are seen as removable, instead of fixed (I guess because ahci is set, so should be normal)
- the two storage volumes have been encrypted before encrypting C:, and have different psw from C: (shouldn't matter either, but you never know)
