 Device menu

    Clicking on the "Device" menu will open the submenu shown below.

    NOTE - If the disk is in use, all the options will be inactive: disable the disk to use the commands related to the device.



Initialize device

    The device initialization process is an operation that is performed only once when the device is still virgin. At the user level, this process takes the form of setting the activation password while, in more detail, encryption keys are generated inside the device that makes each xCoreDisk different from any other.

    Clicking on this menu item opens the following dialog box inviting you to create the new device password:

    This password is the one that will be later requested to activate the disks and for all operations that require access to the device itself. It can obviously be changed at any time but must always be chosen with great care.


   The choice of password

    The choice of the password is in general an aspect overlooked by the end-user, even though it is the password that constitutes the last security stronghold of the user's data.

    This is certainly not the place to deal with the issue thoroughly, but we want to underline some of the key aspects to keep in mind in the selection process.

  • avoid passwords that contain personal data (dates, names ...) or that can lead back to your preferences (favorite authors ..., places of holiday in which you have been ...)
  • use long passwords that possibly contain uppercase, lowercase, numbers and special characters (such as !, ?, &, #...)


    Once selected and entered in the two fields of the dialogue, press "OK": the dialogue will close and the device will be immediately initialized with the password indicated.


      RW Password and RO Password

    The device allows memorizing two distinct passwords, the RW Password (Read/Write) and the Password RO (Read-Only). In the initialization phase, the user is asked to choose the RW Password while the Password RO is simply set identical to the RW password.


    NOTE - It is also possible to assign a name to the device in the case in which it is necessary to distinguish between different devices. The name can also be changed at any time.

Change password

    This command opens a window that allows you to change both the Read/Write disk password and the read-only password.


      RW Password and RO Password

    The Read/Write Password (RW) and the Read-Only Password (RO) are set identical during initialization but later the user can choose to change only one or the other.

    You can choose which password to change by using the read-only password check.

Device backup

    An initialized fly the xCoreDisk device contains a series of information and cryptographic keys that have been generated internally and which are not normally exportable.

     In case of breakage or loss of the device, it would be impossible to recover your data as the encryption keys of the functional parameters and of the disks exist only inside the device.

     For this reason, a backup command has been provided that allows extracting (in an encrypted form) all the data that will then allow to recreate a device capable of working with the previously created encrypted disks.

     By executing this command, the following window opens:


    First, enter the device password, then click on "Browse..." and select the name of the file where the backup data will be saved.

     Insert and then repeat the Backup password (possibly different from all other passwords) that constitutes the password to protect the data that will be saved and click on "OK".


      Backup password

    Saving the operating parameters of the xCoreDisk device, including the secret keys of encryption generated internally, is a delicate operation as this data, if they were to fall into the hands of some malicious, could allow the latter to access the encrypted disks created in priority.

    For this reason, the backup data is encrypted with an AES key generated starting from a new password, the Backup password in fact, which serves only and exclusively to protect the backup data from unauthorized use.


    NOTE - The file generated by the backup function is of type * .txt and the content is printable; it is, therefore, possible to keep this data even in the paper format only and recreate the file only when necessary.

Device restore

    Restoring a device allows to initialize a virgin device with encryption parameters identical to those of another device that has been previously backed up.

    Selecting the menu "Restore device" the following window will appear.

    The dialogue asks to enter the Backup password, that is the one chosen during the backup phase of the device: this password will allow the device to decrypt the configuration data and store it.

     It is also asked to set the main password of the new device: in fact, the restore operation can only take place on virgin xCoreDisk devices that do not yet have the main password which must then be configured.

     Choose "OK" to complete the operation.

Backup disable

    The backup and restore operation can obviously be used to create clones of a device, useful, for example, to allow collaborators to access, perhaps read-only, shared virtual disks, e.g. located in the cloud.

    In order to prevent unauthorized persons from creating additional clones of the device, the backup functions can be permanently disabled by selecting the "Disable backup" menu.

    The window shown will appear that will guide the user in disabling this feature.


      Disabling the backup

    Disabling the backup feature is permanent: once the function that allows saving the configuration data of the device is disabled, it will no longer be available.

    It will no longer be possible to create the file that allows you to generate clones of the original xCoreDisk device.

    We strongly recommend that you disable the backup only after doing this and save the generated file in a safe place.

Device name

    This menu allows you to assign or change the name of the device.

    You can assign a name up to 16 characters in length, a name that can be changed at any time.

     NOTE - The purpose of this name is to be able to distinguish between a device and another in case you have more than one.

Licenses

    Clicking on this item the dialogue shown below appears:


    
Information regarding licenses and support deadlines are reported in this dialogue:
  • Device name - Name assigned to the device
  • Firmware Version - The version number of the device firmware
  • OxySec license expiration - Device license expiration date beyond which the device stops working (assigned by OxySec)
  • User license expiration - Expiration date of the user beyond which the device stops working (assigned by OxySec)
  • Firmware support expiration - Firmware released beyond this date can not be placed on the device
  • Application support expiration - An application released after this date will not work with this device
  • CronoDisk support expiration - After this deadline, the CronoDisk features are deactivated: no recovery points will be created and it will not be possible to open or manage existing ones
  • Serial number - Univocal serial of the device to be supplied to OxySec for updating expiry dates

    NOTE - This information is the same as appears in the open dialog via the "Information" menu (see the specific paragraph)

     By clicking on the "Update" button, the application takes online any new license expiry dates and support for this specific device.

Service disk

    All devices allow to see, when inserted into a USB port, a read-only disk of small size (1 MBytes) with the name "XCDAPP" which contains the XCoreDisk.exe application and some accessory files. This disk is indicated below with the name of Service disk.


    The usefulness of this disk is evident above all in the case of first use and in all cases in which you want to access a disk on a PC on which the XCoreDisk.exe application is not present.

     Clicking on the menu "Service Disk" opens an additional menu that allows you to disable or enable the Service disk: it can be superfluous (and sometimes annoying) the fact that a disk drive appears every time the device is inserted in a USB port.

Enable/Disable

    By choosing this option it will be possible to deactivate or reactivate the Service disk.


     The next time the device is inserted into a USB port, the Service disk will appear or it will not appear depending on the option set.


Create a service disk image

    The application allows you to create an image of a disk of fixed size (1 MBytes) that can then be loaded on the service disk. This allows you to customize the contents of this disk so that you can put whatever you want.

     By clicking on this menu the following window will appear:

    Click on "Browse" and choose the name of the image you want to create; then click on "Create".

     NOTE - If an already existing image is selected, the "Create" button becomes "Open" and it will be possible to manage a previously created image.

     At this point, in Windows Explorer, you will see a new disk of the size of 1 MByte that will have to be formatted and in which you can then copy the files you want to have in the service disk.

     At the end of the operation deactivate the disk by selecting "Disable service disk" from the main menu.

    You can then load the image you just created by following the instructions in the next paragraph.

Upload image

    The Service disk contains the XCoreDisk.exe application in the version released at the time of production of the device. This application, however, is constantly evolving and, for this reason, it has been provided not only that it can be downloaded from OxySec sites, but that it can also be stored on the device by replacing the existing one and now outdated.

    By clicking on the "Upload image" menu the following window will appear.

    Click on "Browse...", choose the image file to upload and click on the "OK" button: a window will appear that warns you that the operation may take some time.

    In the end, the result of the operation will be indicated.

    NOTE - To download the latest released image of the Service Disk refers to this page.
