corrupted external (encrypted) apfs drive on High Sierra (17A365)

Im having trouble accessing data on my external USB disk - it just won't mount...

I get the prompt to unlock, which I do, but it does nothing...

(I should note that I don't actually remember being prompted to convert or encrypt this drive - it was originally non encrypted hfs+)

so Ive tried to access the data manually.

here are the commands I've tried:

MacBook-Pro:~ winston$ diskutil apfs list

I have a disk with the same situation, but it's an external one. It was encrypted with File Vault, and now is completely unreadable.

It doesn't mount, doesn't unmount, doesn't eject, and also freezes Disk Util whenever connected.

When plugged, it asks for the password twice (which is the same I use in a couple other external disks), and doesn't log in. 😟

I have the exact same situation as excellently described here.

Did you guys also had the impression the encryption process did run way too quickly to be honest ??

The encryption did take about 1 minute or two for a 1TB SSD external drive... This is too quick to have worked properly imo....

Yes, I was able to recover everything (with file names and directories intact) with a purchased copy of Disk Drill from the App Store. If your files are unrecoverable, I think it is most likely because your drive is corrupt.

Hello,

I am having a similar issue with my 10 TB drive.

After the volume was converted everything was fine the first time, however the second time it didn't mount and diskutil also isn't able to mount it manually.
