How to Encrypt a Hard Drive Using COMODO Disk Encryption

These following instructions are to guide you step by step on how to use COMODO Disk Encryption’s wizard to encrypt a hard drive or system partition:

  1. Right-click on the drive you want to use (either C: or D:), and choose Encrypt.
  2. Select an authentication method.
    You are to choose either Password and/or USB Stick, You don’t have to select both, but if you’d like extra security, you can select the two options.
  3. Choose Next.
    Pick a hash and encryption algorithm.
    If you chose Password in Step 2, you’ll be prompted to enter a new password now as well.
    Note: The option about ignoring free disk space is checked by default and can be left that way.
  4. Click Next.
    If you entered a password in the previous step, and didn’t choose USB authentication in Step 2, then skip to Step 5.

    Select the USB drive you wish to use as authentication from the dropdown.

  5. Click Finish.
  6. Click Yes to begin the encryption process.

Reviews on COMODO Disk Encryption

COMODO Disk Encryption is a nice program but only because of how easy it is use. Due to the fact that it lacks features like pausing, full support for USB devices, and the ability to encrypt more than one hard drive at once, I don’t recommend this to be your first choice when selecting a disk encryption program.

However, if you’re fine with those disadvantages, then by all means install COMODO Disk Encryption. Given that there isn’t a huge variety of free disk encryption programs out there, it definitely doesn’t hurt to use this one if there’s something particular you like about it.

COMODO produces some fantastic freeware software, like COMODO Backup, a free backup program, and COMODO Rescue Disk, a free bootable antivirus tool. I’m just not a huge fan of this particular product of theirs.

I think COMODO Disk Encryption would be easier to recommend if were still being developed and it had some better features. However, as it is right now, I really think that TrueCrypt or DiskCryptor are better choices, assuming you don’t want to use Bitlocker.
