Hello, I own the WD Mypassport SSD Wifi with 1TB and would like to upgrade it to more disc space up to 4TB (or more). So after research I got the WD blue 2.5 SSD with 4TB and followed this youtube tutorial
Unfortunately, when updating firmware via SD Card, the process stops and all LEDs flash in rhythm 3x - pause -3x. Is this SSD incompatible? According to the Youtube comments, the ‘WD blue 3D Nand’ is compatible and the ‘WD blue SATA 2.5’ would seem not to be, but the serial numbers seem to be the same ( WDS400T2B0A). Does anyone else have experience with an SSD storage upgrade and can recommend a compatible 4TB (or more) that will fit 100%?
The same here!
I have 4TB hdd version v1.03.04
Tired update to 4TB WD blue 3D Nand
I tried firmware v1.03.04; as well as v1.04.17 which everyone said. It seems none of them can be installed to the ssd
After I put ssd on the motherboard, I can directly connect to mac and windows, via USB, it can be recognized well; somehow, firmware on SD card can not push the firmware to the ssd.
Right now, I am trying to disk-to-disk copy(from hdd to ssd); I doubt if it will work, since the wifi password part.
Hi, I had the same idea and tried to clone the 1tb ssd to the 4tb ssd. The result was that the 4Tb ssd was seperated in 2 partitions, one with 1tb space identical to the old ssd, and the rest was unused data. Anyway, I connected it to the MPW motherboard just to test if it will boot, but I only get the same blinking led like before.
I guess that the controller just don’t work with ssd above 2tb
Mine original one is 4t wd blue hdd.
After my 4t to 4t copy done, i will try to reboot. If not, i plan to save the original 4t disk image first, in case i damage it, because i keep playing with it. 
Ok, maybe the controller is compatible with 4tb hdd, but with ssd I’m not sure… haven’t read any post of succesful upgrade with 4tb ssd yet. But yeah, keep on trying, I’m curious how it works out for you, please share your experience with your testing 
I am also interested.
Shame someone doesn’t make an SSD device that has the Wireless passport functionality.
The WD attempt; which is a bit LARGER than the HDD analogous device was a bit ridiculous.
