Can I directly play a video (.avi, .mp3.) stored on a Rohos disk? How to repair Rohos Disk? What is personal encrypted disk ? Rohos is a software system for establishing and maintaining an on-the-fly-encrypted volume (Rohos disk). On-the-fly encryption means that data are automatically encrypted or decrypted right before it is loaded or saved, without any user intervention. No data stored on an encrypted volume can be read without using the correct password or encryption key. Until decrypted, a Rohos disk appears to be nothing more than a series of random numbers. Entire file system is encrypted (i.e., file names, folder names, contents of every file, and free space). Rohos never writes decrypted data to any storage device. I forgot the password - is there any way to recover the files from my Rohos disk? Rohos does not contain any mechanism or facility that would allow partial or complete recovery of your encrypted data without knowing the correct password or the key used to encrypt the data. AES key that is used for decryption is a big random value that was generated when you created your disk. My hard drive is already partitioned. Does this mean I either need to repartition my hard drive, or add a new hard drive? You do not need to repartition your hard drive. When you create a new disk you are required to give the name of the file where you want to store your sensitive information in the encrypted form. That's all. Can I directly play a video (.avi, .mp3.) stored on a Rohos disk? Yes, Rohos-encrypted volumes are like normal disks. You double click the video file and the operating system will launch the application associated with the file type -- probably a media player. The media player starts reading some portion of the video file to RAM (memory). But before that portion gets to RAM, it is decrypted by Rohos. The decrypted portion of the video (stored in RAM) is then played by the media player. The same goes for video recording -- before a portion of a video is written to a Rohos volume, it is encrypted. This process is called on-the-fly encryption/decryption and it works for all file types, not only for video files. See also: Rohos Welcome v.1.2 - Enhanced login screen (the welcome screen).
