TrueCrypt was a highly popular open source disk encryption tool that could keep volumes of hard drive data safe and secure. It was a well-received file encryption utility till it got officially banned by its developers. Once, the original developers posted the official warning that this software is no more under maintenance, and thus might have some security loophole, users got suspicious about the encryption security powers of the tool. Developers also requested the users to move on to other file encryption utility as the tool wont receive any security updates. If you are also planning for a switch, then Diskcryptor is a good option. To learn more about Diskcryptor, read this article.

You might be aware that TrueCrypt got disowned all of sudden, and its anonymous authors didnt even reveal any concrete reasons for the move. But due to the high popularity of this hard drive encryption tool, third-party audits of this software are going on, and these audits have not found any major security loophole in this tool. However, from the security perspective, it is not good to use a software program that doesnt receive security updates. Also, it is risky, to keep your sensitive hard drive data off guard. As an alternative to TrueCrypt, you can use Symantec Drive Encryption, DiskCryptor, VeraCrypt, BoxCryptor, AxCrypt and many more. 

How to Decrypt the Archived data?

Before you encrypt your sensitive hard drive data using a new file encryption utility, you must decrypt the data encrypted by TrueCrypt. To decrypt the data, perform the following steps: 

Open TrueCrypt
Select the drive/partition/folder you want to decrypt, and right-click on it 
That will open the a right-click menu 
Click Permanently Decrypt.
That will bring up a message asking your confirmation on the requested operation of permanent decryption
Here, click Yes.'
Once again the message will pop up asking for your final call on permanent decryption.
If you are sure that you want to decrypt the data, then select Yes. 
Once, you give your confirmation for twice, the decryption process will get started.
Depending on the size of your encrypted data, the process will take some time. 
As soon as the process gets completed, close all the applications, programs, documents, etc. on your computer.
Then, reboot your computer.

With these steps, you have successfully decrypted the data. Now, the data is accessible to one and all. Now, you can get the data encrypted by another file encryption program, such as DiskCryptor. It is also an open source disk encryption tool, and thus, it's completely free.  It can encrypt the whole disk, partitions, single files and folders and external devices such as CD and thumb drives. Also, the software supports encryption through different encryption algorithms such as AES, Serpent, Twofish, and other combination of cascaded algorithms. 

How to Encrypt Data using DiskCryptor?

Download the software from its official website. 
Most importantly, before you start the encryption process, you need to create a bootable Windows disk (LiveCD) with DiskCryptor. You can easily get the steps if you search online. 
Creating this bootable Windows disk is essential because it gets useful in retrieving the encrypted data in case something goes wrong like if you forget the password or some booting problems.

Once you have successfully created the bootable Windows disk, open the DiskCryptor and perform the followings steps:

Then, select the system drive (the drive where Windows gets installed). Usually, its the Drive C:
Next, click Encrypt.
Now, continue following the screen prompts to configure various settings. 
Once you have set the configuration settings, you need to set a password. Your password should include upper and lower-case letters so that it becomes a complex and difficult-to-crack password.
Now, the encryption process will start. The process might take some extra time depending on the size of your data. 
You can continue using your computer while the encryption process is going on.
If you require shutting down your computer in between, then click on 'Pause.'
Then, when you reboot your computer, click on 'Encrypt' to resume the encryption process.
DiskCryptor will list your drive as 'mounted,' once encrypting process gets completed.

Conclusion

The hard drives of computers that host sensitive data, especially the computers in organizations and offices, should get encrypted with a hard drive encryption software. There are various such disk encryption software programs available. DiskCryptor is a good option. It is powerful, has easy user interface and reliable in terms encryption security. Modern operating systems got inbuilt drive encrypting tools as well. You can use the inbuilt programs also. Otherwise, you can go to open source tools like DiskCryptor, VeraCrypt, BoxCryptor, AxCrypt, etc.
