My encrypted external hard drive became undetectable , pls help!

[02111081]

When I tried to mount my encrypted external hard drive, I accidentally disconnected the hard drive from the computer in the middle of encryption. At first, it resulted in the entire application freezing and it became unresponsive. After that, I tried to unplug my hard drive and reconnect to my computer again but it became unresponsive again, so I attempted to click on the menu to look for other option, but it also led to another unresponsive state.

After tried for few times, I was able to click the buttons on the menu and I clicked "Unmount" the encrypted hard drive, which resulted in the entire hard drive became undetectable on my computer, and also in Diskcryptor.

My Diskcryptor is version 1.1.846.118.

Does that mean my external hard drive and its data were all damaged? What can I do to fix it?
