[SOLVED] - sort of... Just a quick update, through VeraCrypt I resumed ENCRYPTING, following a partial decrypt of the drive, rather than decrypting, where I continued to run in to the same error. The encryption picked up from the same point where the decryption had failed, and continued to sucessfully re-encrypt the data it has already decrypted. Following sucessful completion of this process, I was able to mount the drive through VeraCrypt as usual. All data was in tact, with no errors noted on...

Thanks for the help. RE ransomware protection, this is switched off both in windows defender and my anti virus software, have also tried totally disabling all features of both and the error persists. RE resuming encryption from a partially decrypted drive, I ran some test cases on an old disk last night. I encrypted it fully, partially decrypted it, and then pulled the power part way through the decryption. I then plugged it back in and resumed the process, although choosing to resume an encryption...

Just to follow this up. Is it possibly to simply resume, but re-encrypt the drive rather than try to continue decrypting? If I am able to reencrypt then I can mount and recover my data. I can see online its possible to do this process in reverse, i.e, it's possible to decrypt once an encryption process has been interrupted, but not sure if it will work my way round? Thanks again, Dan.

Hi mate, thanks a lot for replying. Run as admin I've done, and get the same error, as for the event logs, nothing noted at the time of the error at all. Thanks a lot.

Hi Everyone, I'm praying to the lord on high somebody may be able to help me. I'm trying to permenantly decrypt a non-system disk. The drive is an external 5TB connected via USB. During the decryption process, I received the following error at around 17% completion: "Access is denied. Source: volTransformThreadFunction:2754". I am unable to mount the drive or seemingly access any of the data on it, and resuming the process gives the same error. I have only ever used the drive as storage. It was encrypted...
