Corrupt file on Synology

I hit a file on the Synology the other day that was corrupt. Is there a Disk Utility equivalent to run?

Oy. I’m real sorry you encountered that stressor.

There are just a couple of tools in the Synology* to deal with file degradation after the fact. I know you don’t need me to say that probability of recovery is a black box, but it’s worth a go. Also, I prefer to have a backup of everything on a volume before I repair the file system on it:

First, look in Storage Manager > Overview. If the volume reports as anything but “✅ Healthy,” you can repair it. Look for the same kind of thing in Storage Manager > Storage Pool. More info here.

I’m always hesitant to give a “here’s how to prevent this in the future” after a bad event, but DSM Self Healing is worth considering, primarily because you keep live data, as opposed to just backups, on the box.

Note that you have to enable “Enable data checksum for advanced data integrity” when you first create a shared folder. But it would be easy enough to recreate your shares and move everything into them.

Also in the future-proofing vein, I absolutely recommend any Synology owner subscribe to Backblaze B2 backup. Enabling it on the NAS is a little nerdy, but worth it for peace of mind. Here’s a guide.

* The Synology OS is called Disk Station Manager (DSM)
