Linkstation Duo LS-WXL wrong messages

[Q-style]

Hello,
I use a LS-WXL09E Linkstation Duo. When accessing the local websettings page in dutch and navigating to "systeem>opslag" (system>storage), there are options to check the drives, format, remove, scan.
When clicking check drive, following message appears (translated from dutch):
"Back-ups can not be performed when diskcheck is active. Formatting a drive can take up to 2 hours. There are no backups planned for the next 2 hours. A backup is being executed."
As you can see, something is going wrong.
I decided this was just an error of wrong messages displayed, so I continued.
On the next screen I got notification of formatting in progress. In terror I pulled the plug to shut the drive down.
As far as I can see, nothing has been deleted.
I'm running firmwareversion 1.61.

After updating the firmware, nothing has changed.
Topic can be closed, I ordered a Synology
