One volume, two names?

[camner]

I have an external drive with one volume named "Data". After I accidentally turned off the power to the drive, although the volume mounts and is accessible through the Finder, other programs (such as BackBlaze) can't access the drive. The message from BackBlaze is

In addition, aliases that point to originals the volume Data are not resolving.

Using Terminal, I see that in /Volumes there are two volumes listed, Data and Data 1. The volume that appears on the Desktop with the name Data is really the volume Data 1.

I restarted the computer, but that didn't solve anything.

How do resolve this? I would imagine there is a way to do this in Terminal, but I'm not Terminal savvy enough to know how to do it.

Open Disk Utility app, select View→Show All Devices, select the top most device (physical device name) for the external drive, click on the First Aid button.

It sounds like the Volume information and possibly the directory on the drive might be corrupted. If Disk Utility first aid can't repair it you might need to use a utility like DiskWarrior to repair it.

Thanks for the tips. Running Disk First Aid did not help, but it is always helpful to start there.

I was finally able to clear the problem by doing the following:

1. Rename the Data drive to something else in Finder
2. Restart the computer. This cleared the duplicate old names
3. Rename the drive back to Data, using Finder

It’s good that you were able to recover the external drive.

I named my external Data drive "Datas" so it wouldn't conflict / be confused with the "Catalina - Data" volume that is mounted at "/System/Volumes/Data"
