Hi there, We have a WD NAS set up at work and has been working great until recently when I tried upgrading the Firmware. Access rate used to be over 30MB/s on a Gigabit network and has now dropped down to 5MB/s. Support with WD has been great up to this point, but now we're at the point where neither of us can figure out what happened. Over a remote connection, WD has rolled back the driver as far back as their database allows (this has been done in stages with a few versions in between to help root out a problem). Nothing has helped. Would anyone be familiar with this situation to tell what has caused this to happen? All workstations which is a mix of XP up to Windows 7 pro have the same result.
