HP LaserJet, OfficeJet, PageWide, ScanJet - HP FutureSmart Firmware Device Hard Disk, SSD, and eMMC Security (white paper)
NOTE: Because SSD and eMMC product memory does not have onboard encryption it will list as “Status: Disk
Cannot be encrypted” (Figures 10); however, any data written to the memory is encrypted by the device
firmware as configured as shown in Figure 9.
Figure 10: EWS Protect Data displaying Status Disk cannot be encrypted
For devices without a hard disk drive, the customer data partition is rebuilt, and the encrypted data is
cryptographically erased after a system power cycle as the encryption keys are not preserved. This provides a
secure erase of all customer data from the encrypted sections of the SSD or eMMC.
SSD and eMMC Impact to Disk Management Features
The following security features are impacted when using SSD as the device system disk.
1.
