Hi,

Indicates a disk error.

How about running chkdsk D: \f command?

Answer 2

Hello

Thank you for posting in Q&A forum.

Based on the information mentioned above, I understand you’re encountering an error on your Volume D after reinstalling your C partition. The specific error code 0x80070017 (“Data error (cyclic redundancy check)”) is usually associated with data corruption or hardware problems.
And from the chkdsk command result, it seems Windows has scanned the file system and found no problems. No further action is required.

Here are some steps you can take to troubleshoot:

1.Please check you can open this D volume and access the data/files/ folders in it. Try to copy them to another safe location as soon as possible if you can access this D volume. If the drive appears accessible despite the error, prioritize recovering vital files before making further changes.

2.Reinstalling or changing partitions can sometimes interfere with BitLocker’s metadata. Open an elevated Command Prompt (run as Administrator) and recheck the status by running:   

manage-bde -status D:  

This can confirm if the drive is encrypted and whether it’s accessible.

3.The cyclic redundancy check (CRC) error (0x80070017) can also indicate physical drive issues. Consider using manufacturer-specific tools to test the health of your hard drive.

4.If BitLocker is blocking access (or if the drive becomes inaccessible), you might need to use your recovery key to unlock it. You can do so with:   

manage-bde -unlock D: -RecoveryPassword YOUR-RECOVERY-KEY   

Once unlocked, you can consider turning off BitLocker encryption temporarily to run additional diagnostics or repairs.

5.Rebuild or repair the BitLocker Metadata, use caution with this tool, and be sure you have a full back up or recovery key available.

repair-bde D: X: -rk YOUR-RECOVERY-KEY   

Not: X would be a drive letter for a destination volume where the decrypted data is written.

repair-bde

6.Check the Windows Event Viewer (under Windows Logs > System) for any disk-related errors that could provide further insights into persistent issues or if the operating system detects hardware failures.

I hope the information above is helpful.
