TS 464 and external backup to USB 3.2 drive

— English machine translation added by Dolbyman –

I’m unable to save files from my NAS to this external USB 3.0 drive connected to the NAS. I’m getting error messages. I followed your instructions and used the yellow icon to access the permissions.

The QNAP-Backup-10TB share is configured with Read/Write permissions for both the admin and administrators groups.

Despite this, I still can’t create a folder on this share using File Station.

The message I get is:

“This action could not be performed. You do not have sufficient permissions or this folder is read-only.”

The QuLog also records “Permission denied” during this attempt.

The drive was formatted as EXT4 directly by the NAS.

Can you analyze why this USB volume is refusing write access even though the share permissions are correct?

Could you please SSH into the NAS command console and run the following commands?

  1. First, use df -h to find the external drive’s device name.

  2. Then, use ls -al <external drive device name>, for example: ls -al /share/external/DEV3301_1

For reference, the output should look something like this:

[~] # df -h | grep external
