Direct answer
For supported removable media, compare the drive's encryption status with data-handling policy, protect the unlock and recovery methods, and test authorized access without exposing sensitive files.
Identify the use case
Confirm the drive owner, data sensitivity, recipients and supported devices. Microsoft describes BitLocker To Go for removable data drives, including supported USB drives and external disks. Compatibility and the ability to manage encryption vary by Windows edition and policy.
Reference: Microsoft: BitLocker FAQ and removable drives.
Review encryption and recovery
Check the relevant drive's encryption and protection state using an approved management interface. Determine where its recovery information belongs and who may retrieve it; do not place recovery passwords alongside the drive or in a general ticket.
Test transfer and return
Use a harmless file to test access on an approved recipient device and verify what happens when the correct credentials are unavailable. Document custody and the process for lost media. Sanitization or secure destruction remains necessary when the drive is retired, according to policy.
Example: transfer to an external partner
Before transferring a protected drive, agree the recipient's compatible device, the approved unlock channel and custody record. Test with a harmless file and keep the recovery secret in a separate restricted system. When the transfer ends, follow the organization's retention and media return or sanitization procedure rather than assuming encryption controls all copies.
Assessment limits
Removable drive encryption does not control copies made after legitimate access or prevent an unlocked device from being misused. Recovery and compatibility must be assessed separately.
Frequently asked questions
Does encrypting a USB drive control every copy of a file?
No. Recipients can make copies after authorized access; apply data-handling controls separately.
Should the recovery key travel with the drive?
Keep it in an approved restricted recovery system, not with the media.
Does encryption replace disposal policy?
No. Follow the approved media disposition and verification procedure.
