Synology NAS Error Code 60: How to Fix It

Q: What does Synology Error Code 60 mean in Surveillance Station?

Error Code 60 in Synology DSM Surveillance Station means that the disk space allocated for camera recordings has reached a critical threshold — typically above 90% full. The NAS sends this alert to warn you that recording may stop soon if space is not freed up.

Q: Will Surveillance Station stop recording when Error Code 60 appears?

Not immediately, but it can stop very soon. When storage is critically low, Surveillance Station may pause new recordings to prevent data corruption. Enabling the 'Recycle recordings when storage is full' option in Surveillance Station Storage settings ensures recording continues by automatically overwriting the oldest footage.

Q: How do I prevent Synology Error Code 60 from happening again?

To prevent this error, enable automatic recording recycling in Surveillance Station, set a maximum retention period for recordings (such as 7 or 14 days), switch non-critical cameras to motion-detection-only recording, and periodically review storage usage using DSM's Storage Analyzer. Adding larger drives or an expansion unit also provides long-term relief.

Q: Can I use an external USB drive to expand Surveillance Station storage?

Yes. Synology NAS devices with USB 3.0 ports support external USB drives. You can format the external drive via DSM's Storage Manager and then configure Surveillance Station to use it as an additional recording destination. However, USB drives are generally less reliable for continuous recording than internal NAS drives, so use this as a short-term or supplemental solution.

Q: How much free space should I keep for Surveillance Station to run properly?

Synology recommends keeping at least 10–15% of your total allocated volume space free at all times. For Surveillance Station specifically, maintaining 15–20% free space provides a comfortable buffer and reduces the frequency of Error Code 60 alerts, especially if you have multiple high-resolution cameras recording continuously.

Abstract

Synology NAS Error Code 60 is triggered by Surveillance Station when the disk space allocated for camera recordings drops to a critical level. This means your NAS is nearly full and Surveillance Station may stop recording new footage to prevent data corruption. Acting quickly is essential to avoid losing live security recordings and to restore normal camera monitoring.
