Formating External Disk is hanging 0% over hours

When formating an external disk, the formating is hanging over hours at 0%. There is no update at the UI. I do not know, if there is something going in the background, the disk is 6TB.
TS-264 with Firmware Version 5.2.8.3359.

Should not take hours. Is this a new drive?

To further isolate the cause of the issue, we recommend connecting the device to a computer and attempting to format it using Windows.

Please let us know if the same problem persists in the Windows environment. Thanks!

It’s already done, after formatting with QNAP didn’t work. I formatted it to ext4 using GParted on Linux. The backup on QNAP with USB one-touch copy works flawlessly. As an additional note, the drive was already formatted as ext4 before. I wanted to use QNAP’s verification function, which is why I formatted it from there.

I’m very glad to hear that everything is working normally now!

Additionally, could you please share the specific model of your hard drive with us? We would like to keep a record of this information to observe if similar models exhibit comparable issues.

Thank you for your assistance!
