Data Security & Privacy FAQ

Privacy protection:
1. I want to return my leased notebook back and want to be sure that all my private data are wiped. Can R-Wipe & Clean do that?
2. I want to clean up my PC from Internet temp file regularly. Can R-Wipe & Clean do it and be scheduled to do this every Friday or another day?
3. I started R-Wipe & Clean but after some time my office lost power for some time. When I started my PC again I found there was no more free space left on my HDD. What I need to do?
4. R-Wipe & Clean does not work on Compact Flash card or other removable media. Why not?
5. Why is some internet history not cleaned? I see only the old history when I start typing a URL address with similar letters. It is the only history that remains.
6. How to set up a command-line command to initiate particular tasks? Is this possible with your software?
7. Is it possible to start a R-Wipe & Clean task after my backup is completed (I am using Ghost)?
8. When I wipe unused space on a disk, each next wiping process takes always more time, maybe because the MFT entries are increasing. Is there is method or program to reduce the MFT entries?

1. I want to return my leased notebook back and want to be sure that all my private data are wiped. Can R-Wipe & Clean do that?

Yes, R-Wipe & Clean is a tool that does such task.

2. I want to clean up my PC from Internet temp file regularly. Can R-Wipe & Clean do it and be scheduled to do this every Friday or another day?

You need R-Wipe & Clean. It deletes and wipes data in such way that any recovery tool will not be able to recover it. There are some different algorithms to wipe you data. R-Wipe & Clean is a software solution to delete and wiped your data.

3. I started R-Wipe & Clean but after some time my office lost power for some time. When I started my PC again I found there was no more free space left on my HDD. What I need to do?

You can re-start R-Wipe & Clean with the same task and as soon as it finishes, all free space will be back. If you have a trouble to re-start R-Wipe & Clean task, please contact our technical Support team.

4. R-Wipe & Clean does not work on Compact Flash card or other removable media. Why not?

In this case please use the R-Wipe & Clean tab in the disk Properties: some removable devices are not included in the main window interface to eliminate unwanted access.

5. Why is some internet history not cleaned? I see only the old history when I start typing a URL address with similar letters. It is the only history that remains.

The Typed URLs check box should be selected to clean your typed URL addresses.

6. How to set up a command line command to initiate particular tasks? Is this possible with your software?

You can use rwiperun.exe /t "TaskName" where TaskName is the name of a task to be run. This command line can be included in any command file.

7. Is it possible to start a R-Wipe & Clean task after my backup is completed (I am using Ghost)?

Probably Yes. Ghost should start R-Wipe & Clean. Check Ghost documentation to learn how to do so.

8. When I wipe unused space on a disk, each next wiping process takes always more time, maybe because the MFT entries are increasing. Is there is method or program to reduce the MFT entries?

MFT is fully under OS control and more likely the problem is on MFT fragmentation.

9. Why should I use R-Crypto instead of using Encrypted File System (EFS) build into Windows XP/Vista, and above?

EFS has severe security concerns which R-Crypto doesn't: * User's private keys are stored directly on the disk. Even system administrators can access them and therefore decrypt the data. * Encrypted files, their names, sizes, etc. are visible. * While decrypting EFS data, Windows creates a temp file with decrypted data. When Windows stops working with such file, it simply deletes it (without wiping). That file can then be recovered using data recovery software, R-Studio, for example. See Issues with EFS for more details. There are some limitations in EFS, too: for example, EFS-encrypted folders cannot be shared over network.

10. Can I recover a forgotten password for an encrypted disk?

No, this is not possible. If you forget your password you won't be able to access the data on the encrypted disk and nothing can be done about that.

11. Can I copy an encrypted disk on any other PC where R-Crypto is installed and work with my encrypted files on it?

Yes. An encrypted disk file-container is just an ordinary file which can be copied to any other PC or storage device and connected using any other R-Crypto installation. At the same time the disk encryption settings should be compatible with a target PC's operating system (for example, selecting AES-256 with SHA-1 hashing algotithm will make an encrypted disk compatible with most Windows OS starting from Windows XP and ending with the most recent Windows 7).

12. How do I backup the data on an encrypted disk?

To backup your encrypted data you can copy an encrypted disk file-container to any backup storage: CD/DVD, tape, network backup location or any other storage device. Note that after backing up you will be able to connect your encrypted disk directly from the backup location, e.g. directly from the CD/DVD.

13. Is it possible to change the size of an encrypted disk?

Yes, R-Crypto provides safe and reliable resize operation for encrypted disks. See R-Crypto documentaion for details.

14. Is it possible to connect the same encrypted disk simultaneously by several users and how can I share an encrypted disk among the users?

Generally no, because this is only possible if all users connect the same encrypted disk in the write-protected mode. To share an encrypted disk among the users in the read/write mode do the following: * Connect an encrypted disk emulating a fixed disk (please see the "Connect an Encrypted Disk" help topic for details) on one computer; * Share the connected encrypted disk using standard Windows disk sharing properties among the network users. Note that using standard Windows disk sharing may result in a security vulnerability as the data will be transferred unencrypted over network.

15. How can I copy the file-container of a connected encrypted disk?

First you need to disconnect the encrypted disk, as you can't copy, move, or burn the file-container of a connected encrypted disk. After disconnecting the disk, you can copy, move the file-container, or burn it to CD/DVD/BR using your favorite software.
