Just installed 4 brand new 2 Tb Wd Red disks on my ts-439 from scratch, raid 5.
Now I get a page saying “Access Denied” from Web-File-Manager.
From the application servers (Multimedia Station, Photo Station, ...) I get: “Note: To use this function, please upgrade the system firmware with the image file enclosed in the product CD or download the latest system firmware.”
System firmware: 3.7.1 Build 20120615, before harddisk update ditto.
Restore of old settings from backup didn’t help.
Restore to Factory Default didn’t help.
