I'm in the progress to encrypt nearly all my drives and so far I had no issues.
However the encryption of the biggest drive has failed at ~30%. My drive just did not response anymore. After a restart my drive was back again and I resumed the encryption process. At ~33% my drive failed again. Restart pc and the encryption, fails after a few percent.

My question is, can I decrypt the partly encrypted drive and if yes, how?
Since I have a backup on a slow external HDD, this is more a "quality-of-life" question.

Thanks in advance for an answer.
