Truecrypt is one of the most powerful encryption software, it has been discontinued due to some politics and security reasons..!
Anyway, if you are using Truecrypt software running on Mac system then you properly got this error due to some errors in your external hard drive.
In this post I will address the solution to the problem and I will provide you with all softwares needed at the end of the post.
Simply follow the instructions in the following steps,
1- Select your drive then select a slot and press “Mount” button.
2- Then press “Options” button and select “Do not mount” option at the bottom, then enter your password and click Ok.
3- Your drive now is unlocked but not yet mounted as shown in photo, this is the most important step because now your drive is reachable and could be fixed. 🙂
4- Now you may try to repair the drive using Mac “first Aid” as following:
But as you know mac utilities are rubbish and useless.. 😷
5- So I recommend using one of most powerful software I have ever used to repair hard drives, it called “DiskWarrior”, I tried almost every hard drive repairing softwares and nothing could compete this one (download link is provided at end of the post):
6- Simply install the software and run it, if your Mac is protected with a password, a window will be promoted, enter you password then click Ok.
Then choose your hard drive which you want to repair and click on “Build”,
The process will take some time depends on your hard drive volume size and how much it is damaged, but at the end it will be repaired so be patient :).
After the process is complete, a new window will be prompted, it shows the report with all details, click on “Replace”
The process will continues to the final step,
When last step is completed, the software will ask you if you want to save the report which contains all details of your hard drive along with the damaged and rescued files information.
Ta da, you hard drive is back 🙂
