I bought a brand new WD MBLD 4TB last week. It arrived Wednesday, I connected it up, switched it on, loaded the CD and away I went. The first job I did was to back up the start point. I then changed the settings from RAID 0 to RAID 1 and left it to complete overnight. The next morning I copied over several thousand files totaling 64Gb without any problems. I could see them and open them from the mapped drive (Z).
A while later I tried to copy some more, but strangely the drive was no longer there. I could not see it as either a “Z” or by using its full path name, nor could I use the browser to connect to it (neither Chrome nor IE). As my home laptop is still on XP I thought I’d try my son’s Windows 7 laptop. I still couldn’t map to the MBLD, but the Win 7 PC could see it as a media server and was able to play music from it.
Throughout all this time the MBLD was sitting there with a steady green light showing. Several forum posts here suggested trying a rest or if that failed then powering it down and back up again. So it held the reset button in for 4 seconds - no change. As nothing was writing to it, I unplugged the Ethernet cable from the NAS, waited 60 seconds (it was a bit longer) then switched off.
When I turned it back on the LED on the front returned to it’s steady green state, but I still couldn’t use the utility supplied on the CD to communicate with the device, nor could I map to it. Eventually I downloaded the WD Link Software and had a degree of success with that. It searched and found the device, but said it had failed. When I looked at the front of the MBLD the LED was steady red.
I powered it down again following the routine described above and then powered it back up. The LED on the front panel was green. I ran the WD Link Software again. It found the device, but then said it was initialising. It stayed like that for hours until I powered it down.
Any ideas what could be wrong? Error messages have been few and far between. Any that I have had related to the messages from the browser being rejected by the device.
