 Access to disks

Foreword

    In the following paragraphs it will be presented a step by step explanation of the needed operations to access configured disks. If not configured refer to the specific page of this manual on the configuration of MicroSD memory.

    NOTE -  In some sections there is a panel that explains some aspects of the operation performed by CryptoSD. Such information is not necessary for its usage, but are addressed to whom already have the basic knowledge of disks management and file systems and want to have a better understanding of how CryptoSD works.



Access to one or more unencrypted disks

    By inserting into a USB port a CryptoSD device with a configured MicroSD memory card with one or more unencrypted disks, the operating system mounts such disks and starts the Autoplay window or, if the disk is new, it will ask you to format it.

    You can view the type of disks using the program CryptoSDLogin.exe.

  • Open the program CryptoSDLogin.exe.


  • If not already connected, plug in the CryptoSD device with the MicroSD memory already inserted..
  • Depending on the memory configuration the program will display the number of available disks and the operating system will open those already available. Below there are some screenshot examples related to different configurations.


MicroSD configured to export a single not encrypted disk G:


MicroSD configured to export three disks. Disk G: is not encrypted while disks H: and I: are crypted


    NOTA - Clicking on the "INFO" bar of a given disk it will be displayed a window containing a summary of the configuration features of that disk. For instance clicking on the "INFO" for a non encrypted disk it will appear something like it is shown below.


Information about the disk G:, the only one disk configured onto the memory card


   

In depth – The “INFO” button

    The "INFO" bars on the main screen of the application CryptoSD Login are useful for understanding what kind of disks are present.
  • Grey INFO bar - No disk is present
  • Green INFO bar - The disk is currently available for both reading and writing
  • Yellow INFO bar - The disk is currently available just for read-only access
  • Red INFO bar - The disk is currently not accessible at all

    Note that an encrypted disk is shown with a red bar as long as the user unlocks it entering the password. At that point the bar will turn to green or yellow depending on whether it was entered the main ("Read/Write") password or the read-only one.

Access to an encrypted disk

MicroSD memory configured with a single encrypted disk

    Let’s suppose to have a MicroSD configured to export a single encrypted disk.

  • Insert a MicroSD memory into the slot on the CryptoSD device and insert it into a computer's USB port.
  • Run the program CryptoSDLogin.exe. It will show the following configuration:



  • By clicking on the “INFO” bar the features of the disk will be shown.



  • To access the disk, type the password in the provided entry and press the "OK" button



  • The disk will be recognized by the operating system that will start the Autoplay window or, if necessary, ask you to format the disk. The application will now show a green bar to indicate that the disk is accessible.


MicroSD memory configured with multiple disks

    Let’s suppose to have a MicroSD configured to export two disks one of which encryted.

  • Insert a MicroSD memory into the slot on the CryptoSD device and insert it into a computer's USB port.
  • Run the program CryptoSDLogin.exe. It will show the following configuration:


  • The non encrypted disk G: will be automatically mounted by the operating system and start the Autoplay. The encrypted disk H: will appear in Windows Explorer but you can’t access it (it will be displayed grayed-out).

    NOTE - Depending on the operating system configuration it may happen that the non active disks won’t be shown at all.



  • In the CryptoSD Login application, select the disk H:, enter the unlock password in the provided entry and press the "OK" button.
  • Then the disk H: will be mounted by the operating system that will start the Autoplay. The image of the disk H: will be no longer greyed out.



  • The “INFO” bar related to the Disk H: will turn into green to indicate that now the disk can be accessed in both reading and writing mode.




  • By clicking on the “INFO” bar the configuration features of the disk H: will be shown.

Access in read-only mode

    If you have set the read-only password for a disk, it is then possible to access it in that mode, that is without the possibility to change data on the disk.

    Let’s suppose you have a MicroSD device configured to export three disks (G:, H: and I:) two of which are protected (H: and I:). Suppose also that for one of the two drives (namely H:) it was also set the read-only password.

  • Insert a MicroSD memory into the slot on the CryptoSD device and insert it into a computer's USB port.
  • Run the program CryptoSDLogin.exe. It will show the following configuration:




  • Select the disk H: note that you can choose if enter the “Read/Write” or “Read Only” password.

   

In depth – Read only password

    The fact that the application allows you to choose between "Read/Write" and "Read Only" password for one of the encrypted disks means that the read-only password was previously set.
    The read-only password can be changed at any time with the program CryptoSDPasswdMan.exe: however to change it you must know the main password (Read/Write) set during initialization or changed successively.


  • By clicking on the "INFO" bar of the Disk H: you can verify that this record was also set with a read-only password, as shown below ("Read Only Password set: YES").



  • Check the radio-button “Read Only”, insert the proper password and click the “OK” button.
  • The “INFO” bar will turn into yellow color to indicate that the disk was mounted in read-only mode.




  • The operating system will start the Autoplay and the disk will be accessible in read-only mode.

    NOTE - After mounting a read-only disk, you can always enter the password for read/write access in order to have full read write control of the unit.
