 You can can Group Policy settings to require that data drives be BitLocker-protected before a BitLocker-protected computer can write data to them. For more info, see [BitLocker Group Policy settings](bitlocker-group-policy-settings.md).
 When these policy settings are enabled, the BitLocker-protected operating system will mount any data drives that are not protected by BitLocker as read-only.

+BitLocker in Windows 10 lets users choose to encrypt just their data. Although it's not the most secure way to encrypt a drive, this option can reduce encryption time by more than 99 percent, depending on how much data that needs to beencrypted. For more information, see [Used Disk Space Only encryption](bitlocker-device-encryption-overview-windows-10.md#used-disk-space-only-encryption).

 ## What system changes would cause the integrity check on my operating system drive to fail?
 
 The following types of system changes can cause an integrity check failure and prevent the TPM from releasing the BitLocker key to decrypt the protected operating system drive:

 In BitLocker, recovery consists of decrypting a copy of the volume master key using either a recovery key stored on a USB flash drive or a cryptographic key derived from a recovery password. 
 The TPM is not involved in any recovery scenarios, so recovery is still possible if the TPM fails boot component validation, malfunctions, or is removed.

 BitLocker To Go is BitLocker Drive Encryption on removable data drives. This includes the encryption of USB flash drives, SD cards, external hard disk drives, and other drives formatted by using the NTFS, FAT16, FAT32, or exFAT file systems.

+## Can I use EFS with BitLocker?
+
+Yes, you can use Encrypting File System (EFS) to encrypt files on a BitLocker-protected drive. BitLocker helps protect the entire operating system drive against offline attacks, whereas EFS can provide additional user-based file level encryption for security separation between multiple users of the same computer. You can also use EFS in Windows to encrypt files on other drives that are not encrypted by BitLocker. The root secrets of EFS are stored by default on the operating system drive; therefore, if BitLocker is enabled for the operating system drive, data that is encrypted by EFS on other drives is also indirectly protected by BitLocker.

 ## Can I run a kernel debugger with BitLocker?
 
 Yes. However, the debugger should be turned on before enabling BitLocker. Turning on the debugger ensures that the correct measurements are calculated when sealing to the TPM, allowing the computer to start properly. If you need to turn debugging on or off when using BitLocker, be sure to suspend BitLocker first to avoid putting your computer into recovery mode.
