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.

Command line for Rohos Disk

Rohos Disk Encryption has a few command line options, so that the encrypted disk can be connected and disconnected by using shortcuts or a BAT file.

agent.exe "c:\My Documents\rdisk.rdi" /letter:Z: /log

or

agent.exe \_rohos\rdisk.rdi

Request a password to connect Rohos disk rdisk.rdi.

/letter:Z: – the drive letter it will be connected (optional)
/log – allows creating a log file (agent.log) when performing the operation. Only when the disk is mounted from a USB drive.
/password – allows specifying a password for Rohos disk

Second option would unmount the disk, which is located on the USB drive.

agent.exe /unmount:Z: 

Disconnect Rohos disk Z:

agent.exe /unmount:ALL
Rohos will disconnect all of  the Rohos drives.

Rohos Disk shortcuts

Rohos Disk Encryption allows creating a disk shortcuts on the desktop or any other place. When you double click this shortcut you will be prompted to enter a password to connect this Rohos disk.

On the screen shot you can see how to make disk shortcut for any Rohos disk using “Tools” menu:

After you created disk shortcut, you may find it on the desktop and edit properties to specify the drive letter it will be connected with:

Does not require Admin rights to open encrypted disk.

Encrypted Rohos Disk BrowserThe new version of Rohos Disk (1.18) includes new utility, Rohos Disk Browser. This enables you to open and view the contents of secret partitions on a USB drive on any other computer, even if you do not have administrative rights.

Rohos Disk can password-protect a portion of a USB flash drive, by creating a virtual encrypted partition. The partition is protected by a password, and can be opened on any computer. Now, even if you are in an internet cafe and have no administrative rights, you can still have read access to your secret partition with the help of the Rohos Disk Browser utility. This means that you can open any file and read any data. Naturally when you are at your home or office computer, you will still be able to work with your encrypted partition as usual.

On a strange computer you can always open your protected partition on the USB flash drive (in read-only mode) with the help of the Rohos Disk Browser utility. This makes it possible to open or copy only one particular file or directory, without granting access to every file.

This feature is enabled in a Rohos Mini Drive program – FREE and tiny USB drive encryption tool.

Pulling USB drive out of the computer with Rohos Logon…

We always wanted to tell you that in order to use the program Rohos Logon Key, you have to set up the option “Optimize USB drive for quick removal” (read farther).
And our user Patrick reminded us about that:

“I am trying Rohos Logon Key . I have two questions. If you pull USB drives out of the computer, you risk losing data or killing the drive. Couldn\’t this cause a problem if using Rohos in this manner? …”

Patrick meant that before pulling the USB drive out you should use the dialog Safe hardaware removal:

Safe USB drive removal dialog.

But when you use Rohos Logon Key it’s useless to use this Safe Removal dialog (though you may do it if you use PIN code and lock the system by hotkey Win+L), because the quick computer lock-out by using USB key becomes senseless. In this case in Windows you should set up the option To optimize USB drive for quick removal:

Optimize USB flash drive for quick removal to prevent data loss

The red lines show the actions that go one after another: My computerUSB disk properties – Hardware page – double click on the name of the USB diskPolicyOptimize USB drive for quick removal check box.

More than 20 USB flash drives were at our disposal, and only 1 of 3 “has died” suddenly (stopped recognized by Windows on the next day).

Native language characters disappears in Linux’ net drive.

Not long ago, one of our users in Forum has suggested an interesting idea how to use Rohos disk. Actually, it concerns all the similar programs virtual-disks, but it seemed, we are the first.

So, here’s the issue. If users have the Linux samba server, they have access to the network folders on that Linux server for storing their files there. Thus, very often during working with the files that contains specific (native) letters of your mother tongue(ä, ü, Б, ц), the letters get lost.

Here’s what our user has written (translated from german):

… the program can solve the problem by creating on the network shared folders big-sized virtual disks. Cause files which contain the characters of your language in file names get lost, because the network folder is on the Linux server with Japanese BIOS.

This is how it looks:

Thus, if you keep Rohos disk on Linux computer in the network folder, and use (mounting) it in on your computer or in Windows server,  these letters in files names will be unaltered (the file system NTFS accomplishes it cause it is UNICODE enabled).

 

USB flash drive encryption softwares

In Internet one can easily find a lot of programs on the subjects like “USB flash drive security”, “Set up password on USB flash drive”, or “Encrypt USB flash drive”. Each of them has its pros and cons. Let’s take up the issue in detail.
Programs for USB flash drive encryption are divided into 2 groups:

  1. The programs that encrypt the separate files on the USB flash drive. The secure files are stored in the special (hidden) folder on USB disk. Certainly, the files names are modified, and the contents are encrypted. You can open the file only in the program, at the same time the file is decoded on the USB disk and then opens in the associated application. At the end it is required to give a command “to update protected file”.

    Such programs are “Remora USB guard”, “USB Vault” “Folder Lock”. If you wish you might replace these programs by usual password archive RAR, ZIP (with built-in encryption feature). It automatically renews the archive file, if you have opened it in the archive and changed it.

  2. The programs that create virtual encrypted disk, where all the files are automatically coded/ decoded without direct user command. The disk is fully contained in the USB flash drive.
    These programs have a number of advantages:
  • A user works with the protected files directly. It is not necessary to indicate what file should be decoded
  • The files are being automatically coded/ decoded as required
  • Temporary files are also kept as encrypted ones
  • It is possible to work with a virtual disk from any program

    The main disadvantage is that you should have Administrative privileges to open this virtual disk, because the program loads the disk driver, i.e. if you want to open the disk in Internet cafe, you will not manage it by 99%. However, such kind of program is right for secure carrying over the files from home and work and vice versa.

There are also the programs that are usually included in the stand of some USB flash drives (for example Transcend Jet Flash). They divide the USB flash drive memory into 2 partitions. 2 Removable disks are showing up in the system while connecting. The first disk is open, the second one is entirely
encrypted. If you want to open it for reading/recording, you should enter password in the special program.
