About Removable Media encryption
Definition reminder
Note again the definition of removable media defined above. In addition to this
definition, floppy disk drives (FDD) and Magneto-Optical (MO) drives are supported.
Free space on media
When applying encryption to FDD, the floppy must contain enough free disk space to
encrypt the files. If a file is larger than 50% of the floppy, the encryption will fail and
the file will be left in plaintext. There is no warning message informing the user about
this.
I/O utilization value for FDD encryption
For removable media encryption enforcement to work better on floppy disk drives, it is
recommended to increase the I/O Utilization value to 80%. This will have no impact
on the rest of the system and can be safely done.
CD / DVD Encryption
This option enforces encryption on CD and DVD write operations. The encryption is
applied on a sector level to the entire CD/DVD, meaning that all content being written
to the CD/DVD will be encrypted. Thus, it is not possible to encrypt only selected files
out of several in a burning session; all files being burnt will be encrypted.
In order to read an encrypted CD/DVD, the Endpoint Encryption for Files and Folders
client needs to be installed, i.e. it is not possible to read the encrypted disk without
the client.
The encryption is independent of the application used to burn the CD or DVD (with one
exception, see note below); the encryption will be applied whether or not the files
being burnt are already encrypted. This is an all-or-nothing encryption feature.
When trying to read an encrypted CD/DVD from a client without Endpoint Encryption
for Files and Folders installed, the user will see no content, i.e. it will appear as a blank
disk. If the user tries to burn data onto an encrypted disk from a system without
Endpoint Encryption for Files and Folders installed, there will be error messages saying
that the data structure and file tables of the disk are invalid; the burning will therefore
fail.
