I bought a refurbished Time Capsule, erased the hard drive

Customer Question

I bought a refurbished Time Capsule, erased the hard drive using Airport Utility, and set up Time Machine to back up to the Time Capsule. It tries, but I keep getting an error after awhile saying it can't complete the backup.

You mean you setup the Time Machine to backup your Macbook right?

Reboot into the Recovery HD by choosing the ‘Apple‘ menu > Restart, then hold down the ‘Command’ + R’ keys on the keyboard during the start up process. When you see the Apple Logo you can let go. When the machine boots you may have to choose your language then you will see the OS X Utilities screen. Select the Disk Utility and then select Continue. Then in Disk Utility select Macintosh HD in the left column (if there are two with that name or it is named something else choose the first indented item) and then on the right select the First Aid tab then select Run.

I tried that and it backed up more than it did before, but eventually failed.

Try erasing the drive again but choose the Security or Option button and move it one notch to the right to secure erase.

I did that, then took another look at restarting in Recovery mode. FYI - I noticed that my hard drive could not be rendered any First Aid; the First Aid button was greyed out. I quit Disk Utility, quite Recovery mode, and went to choose my disk as the startup disk. It said that the disk was encrypted, and asked for a password ***** unlock it. Did that, then went back into Disk Utility and discovered that I could use First Aid on it now. It took quite a while; the only thing I was in the details that looked like it was fixing something was "repairing file system." Having finished that, I started Time Machine backup again. It's still going, of course. But this is the first time it has been able to estimate the time to completion (21 hours) so that might be a good sign.

OK did you have Filevault turned on?

The backup just quit and I got the attached...
Customer: replied 1 year ago.
FileVault is on.

I would do a hard reset of the TC and start over:

Customer: replied 1 year ago.
I did that as a first resort.
Expert:  Mike replied 1 year ago.

OK I assume you got a warranty with the refurbished TC? I suggest you return it
