How to backup data on the USB drive secured partition

Rohos Disk Encryption software allows users to have  new secure storage on a computer or USB flash drives. In this post we would like to underline the importance of data back-up especially if you are using Rohos disk on USB flash drives. Due to nature of USB flash drives (portable and special memory design) its memory is subject to external influence and the data integrity is not so strong.

Most people realize the importance of data back-up after the disaster has happened:

  • they lost USB stick with secured partition on it
  • after a couple of month of using secure partition on the USB flash drive it has numerous of File System errors due to missed Disk Check procedures
  • after an occasional (but still possible) USB memory data sector failure a part or entire secure Rohos partition is damaged

How to safely re-format USB Flash Drive into NTFS

Rohos Disk Encryption software creates hidden and protected partition on the USB flash drive. With the help of the program you may password-protect a part of your USB flash drive and open it on any computer by simply entering your password.

Since most USB Flash drives, even the larger ones, are normally formatted with the FAT32 file system – there are limitation on the maximum size of the encrypted partition of 2 or 4 GB (max file size limitation).

In order to create a secured partition that is bigger than 2 Gb you need to change your USb stick into NTFS format.

Before changing the file system on a USB drive care should be taken to backup any critical data on it just in case the process does not work.

Silicon Power F600 FingerPrint Disk. Review

We’d like to present you the review of Silicon Power F600 FingerPrint Disk with 1Gb volume with on-board fingerprint scanner. It’s not compatible with Rohos Logon Key.

Silicon Power F600 features:

  • All flash memory is protected. There is no Open part.
  • Biometric or password protection of the USB flash drive (or both, fingerprint + password).

How the device works:

Once the USB drive is plugged in in “My computer” window will appear two devices, removable drive (for example G:\) and virtual CD-ROM (F:\).



If you try to access disk G:\ now it will not open up. It means that it’s locked. To unlock it you should start up the file: “F:\FingerPrint.exe”, and in the emerged window choose the icon “Unlock”. After this should open up the “fingerprint” authorization window. In this window you may either enter your password or register your fingerprint.


If you have successfully got authorized the disk G:\ will get unlocked,  and in the taskbar will appear new icon:


If you double-click on it the program main menu will come up:


From this window you may encrypt the disk back just by pressing the “Unlock” button.

Registering fingerprints:

First you should open the program’s main window and choose the “FP Manager” button. Then enter your name and press the button with the right arrow, and the following window will open up:


Further choose the finger and slide it three times over the scanner, then press right arrow button. In the next window you may set up a password if needed.

“SecretZIP” feature:

In the main menu choose the “SecretZip” button, enroll using fingerprint. The following window will appear:


There are three buttons on the window:

  1. Create Archive – You choose the files and folders you need, and put them in a usual archive *.zip or encrypted *.exe, that could be unzipped only using this program.
  2. Unzip the archive – Just choose beforehand created *.zip file and unzip it into a chosen folder.
  3. Decrypt file – Choose beforehand created encrypted file of *.exe format and the program itself will decrypt it.

Data Synchronization:

In the program’s main menu choose the “Data Synchronization” button, enroll using fingerprint”. The following window will appear:



The left icon will lead to the Settings window, the right one to synchronization window:


There are three buttons (folders) for your disposal. Under each of there there is a button with arrow. If pressing on one of them there will appear the window where you should indicate the path to any folder that is on hard drive and path to the folder from the flash drive for the program to “know” what to synchronize with what. Now you may press the corresponding button (”syncr. my DataSync folder”, “syncr. my favorite folder” or “syncr. my document folder”), then press the“Synchronize” button and that’s it.

Locking computer:

In the program’s main menu choose the “PC Lock” button, enroll using fingerprint. The following window will appear:


Here you should set up locking settings and press ОК. Now to lock computer you should unplug the flash drive, and to unlock it to plug the flash drive back. Locking the PC is possible only after the flash drive itself is unlocked.


  1. The device doesn’t work under Windows Vista
  2. On the PC without admin rights the device is not accessible
  3. Presently it’s not compatible with Rohos Logon Key
