Chkdsk An unspecified error occurred 6c6f6766696c652e 29c

Question

UPDATE: It was a bad SATA cable.

I ran the chkdsk /R command on an external WD 1TB hardrive connected via SATA. Here is the output log from chkdsk from event viewer. Not sure what the error message means?

Chkdsk was executed in read/write mode.

Checking file system on E: The type of the file system is NTFS. Volume label is Backup Drive.

Solution

0xc000009d = STATUS_DEVICE_NOT_CONNECTED

Looks like Windows lost the connection to the drive. Replace the cable and check you still have the issue.

nice to hear that a new cable fixed it. Accept my answer to "close" the question.

When chkdsk was finished and I clicked on the device in Windows Explorer it showed it was not connected. It might be a cable issue.
