Synology NAS Error Code 32: How to Fix It

Q: Will Synology Error Code 32 cause me to lose my data?

In most cases, Error Code 32 does not result in data loss. The file system check (fsck) repairs logical inconsistencies in the file system structure rather than deleting your files. However, if the underlying drive has physical damage or if the corruption is severe, some data may be unrecoverable. Always back up your data before running the repair to be safe.

Q: How long does the Synology file system check take?

The duration of the file system check depends on the size of your volume and the number of files stored. A small volume (1-2TB) may complete in 30-60 minutes, while a large volume (8TB+) can take several hours. During this time, your NAS services will be temporarily offline. Avoid interrupting the process once it has started.

Q: Why does my Synology NAS keep showing Error Code 32?

Recurring Error Code 32 usually points to an underlying cause such as a failing hard drive, frequent power outages causing unclean shutdowns, or a hardware issue like a faulty drive bay connection. Check your drive S.M.A.R.T. data for signs of failure, invest in a UPS to prevent power interruptions, and inspect drive connections. If the error keeps returning after repairs, consider replacing the affected drive.

Q: Can I still access my files when Synology Error Code 32 appears?

It depends on the severity of the corruption. In some cases, DSM will still allow read access to the volume while flagging the error. In other cases, the volume may be mounted as read-only or taken offline entirely. Do not attempt to write new data to the volume until the file system check is complete, as this could worsen the corruption.

Q: Do I need to rebuild my RAID array after fixing Error Code 32?

Not necessarily. Error Code 32 is a file system error, not a RAID failure. If your RAID array shows a 'Normal' or 'Healthy' status after the file system check completes, no rebuild is required. However, if a drive failed alongside the file system error, you may need to replace the bad drive and allow DSM to rebuild the RAID array automatically. Always check both the Volume status and the HDD/SSD status in Storage Manager.

Abstract

Synology NAS Error Code 32 indicates that DSM (DiskStation Manager) has detected an inconsistency in the file system and is requiring a file system check (fsck) before normal operation can resume. This typically happens after an unexpected shutdown, power outage, or abrupt disconnection while data was being written. Running the file system check will scan your volumes for errors and attempt to repair them, and in most cases your data will remain intact — but backing up critical data beforehand is strongly recommended.
