I undertake to back up the data I need or remove the drive before shipping. If I intend to reuse encrypted drives, I will store the associated recovery information, particularly the BitLocker recovery key, outside the device and check that I can access it. If I cannot do this, I will discuss it with you before shipping.
Changes to UEFI / BIOS or the TPM may cause BitLocker to request the recovery key. The client is responsible for backing up the recovery information and ensuring it remains accessible. Recovering lost keys and decrypting data are outside our service. Without the correct recovery information, access to encrypted data may be permanently lost.
I undertake to pay for shipping both ways, pack the device securely for transport and include a prepaid return label. I will check that the addresses on both shipping labels are correct.
