I was trying to encrypt my USB external hard drive (1 TB, mounted to E:) using BitLocker, and after the encryption got 10.1% finished, I accidentally shut down the computer. After restarting, I tried to resume the encryption, but it gives me an error: "Encryption could not be resumed. The device is not ready." I've tried using >manage-bde -resume E: but it returns the same error with code 0x80070015. I also get the same error if I try to go to the Control Panel and Turn off BitLocker.
Running >chkdsk E: shows several corrupt attribute records, but I haven't tried running that with /F since I'm worried that might make it difficult to properly decrypt BitLocker.
Are there any recommendations on how to either resume the encryption or decrypt the 10.1% it's already done? I've heard there's a BitLocker repair tool, but I don't have an empty 1 TB drive to use for that.
System: Lenovo y510P running Windows 10 64-bit

That is not due to partial encryption. Never at any point (not during, not after encryption) should you be unable to access your files. So these are file system errors. You will need to do checkdisk /f.
It might hurt, yes, but there is no other way. That's why one creates backups, anytime.

The drive is unlocked, right? So you should backup your data, format the drive, restore the data and re-encrypt. Everything else might lead nowhere.

The drive is unlocked, but I can't access the contents because it appears to be partially encrypted.

Ok, I'll try doing the chkdsk repairs then. Thankfully I do have backups (I've learned that the hard way in the past), so I'm not terribly worried about losing a lot of important data.

Running chkdsk /F on it fixed the drive errors and I was able to decrypt the drive :)

Good, glad to hear.

Thank you for the fix! To be more specific you need to run command prompt as an admin and type "CHKDSK /f X:" X being the drive letter of the drive. Hit yes when you get the "force dismount" warning. Never using bitlocker again. lol

Hi,
I have faced the same problem as mentioned above, 1 TB external hard drive encryption was accidentally stopped, after then. it is saying : "Encryption could not be resumed, the driver is not ready".
I have used manage-bde and it is giving the same error with code 0x80070015.
I have also tried chkdsk/f D: and it is saying ; "The type of the file is RAW. CHKDSK is not available for RAW drives."
Any other solution please?
Thanks

No, that is not the same problem. The original problem was: "drive is mounted, file system is recognized, but the partial encryption cannot resume". Yours is: "drive is not mounted". So your problem is worse and your only chance is to use repair-bde.exe on the command line.
