How to Repair Rohos Disk

The following guide - How To Repair Rohos Disk - is a part of Rohos Disk Help files. We were prompted to publish it in the blog due to many users appeals. The Rohos guide will help you to: Create Password Reset File, Recover Disk, Restore Encrypted Part on a USB flash drive, Check Disk.

Create password reset file

(backup copy of cryptographic keys for disk encryption)

The program allows to create a password reset file for Rohos Disk. If you forget disk password you will be able to set new password and get access to the disk by means of this file. It makes no difference how many times the disk password was changed, this file is created once.


How to create password reset file:

  • Press Create password reset file link in Rohos Disk main window
  • You should specify path to disk image-file in opened dialog. If main disk is on, this path will be set automatically. You may also specify whatever disk image you want to have
  • Then enter disk password and press Create backup
  • Spare copy will be created

Warning: The backup file must be kept in secret otherwise another user can use it to access the encrypted disk.

Disk recovering

Warning: Make sure the disk is turned off before it’s recovered.

This function helps to recover Rohos disk or disk password.

How to use this function:

  • Go to Restore disk link in Rohos Disk main window

In opened dialog you should click on:

1. Specify path to disk backups file (*.RDI1 or *.RDX). Path to disk backups file (*.RDX file - for disk password recovering, *.RDI1 file for disk recovering) RDX file must be created by user beforehand. RDI1 file is created automatically by program with disk image.

  • the program automatically opens the folder that contains your backups file *.rdi1
  • click on appropriate *.rdi1 file and then Open

2. Specify path to disk image-file *.rdi.

  • Enter in password input line:
    New disk password - if you recover password (*.RDX file was chosen)
    Current disk password or initial disk password (if password was changed) - if you recover disk

  • Press OK - There will be an attempt to turn on the disk.

The disk can turn on but it won’t be formatted - DO NOT FORMAT IT because it can lead to data loss.

If disk is not formatted it means that you’ve used wrong *.RDX or *.RDI1 file from wrong file image.

If you recover main disk and it is still shown as unformatted:

- try to open favorite disk with “Connect more…” command.

Restoring Encrypted part on the USB flash drive

When you can’t find the disk’s image on the USB you should look for the Rohos image in the Folder F:\_rohos\ (where F is the letter of your USB flash drive). Usually disk image file looks like rdisk*rdi (its size is from 10 Mb to several Gbs). The Folder _rohos is hidden and in the file explorer it’s not seen. In order to open it you should:

  • Open menu Start -> press Win + R
  • Type in “F:\_rohos\ (or any other letter of your USB flash drive) and click OK

If you restore disk, then in the dialog box *RDI1, *RDX in the file name field you should choose F:\_rohos\ and then press Enter to be directed to the Folder.

Disk checking

By means of this command disk will be checked for errors. It helps in case disk doesn’t turn on or it is shown as unformatted. This command can be used only when the disk is on.

This command can be started manually:

- Start button -> Execute
- Enter command line “chkdsk.exe r: /f /x”, where R: your disk letter.
- After command execution there will be a window with black background. You need to wait till it is shut.
- After disk checking ends you may try to turn it on and turn it off again.

The disk is shown as unformatted

Warning: In case you used Rohos disk beforehand and it is shown as unformatted after another turning on then DO NOT FORMAT IT!.

  1. Right after disk creation Rohos program tries automatically format it in NTFS. In some cases that can’t be done so disk remains unformatted and you need to format it manually.
    - Open My Computer window.
    - Right mouse button click on disk icon - choose Format command.
    - Press OK in format disk dialog.
  2. If you used Rohos disk before then you need to do some actions:
  • Restart your computer and try to turn disk on again
  • If it doesn’t help then start ‘check disk’ command (for example with “chkdsk.exe r: /f /x” command line where R: - your disk letter). Then turn disk off and turn it on again. Also you can check your HDD on errors.
  • If it doesn’t help then try to turn disk on with “Connect more…” command (you may use USB flash drive as a password)
  • If it doesn’t help then use Recover disk dialog
  • If it doesn’t help then contact us
