Buffalo NAS Pro Duo is full and want to upgrade from 2TB to 6TB - How to??

[fat2fit]

Hi! I have a Buffalo NAS Linkstation Pro Duo LS-WVL2.0TL/R1-US and it works great, but I need more storage. I want to install bigger hard drives, so I bought 2 brand new Western Digital 3.0 TB drives, Model MDBH2D0030HNC-NRSN. I tried to follow the youtube video https://www.youtube.com/watch?v=5hXAGPHswu4 for the pro duo diskless system. When I installed both new drives, I get a red flashing LED on the INFO/ERROR light. It looks like E15? This also happens with just one of the new drives installed in the Linkstation. I also tried keeping one of the old working drives drives in and added one new one. After it boots up, I get a I12 on the LED - The RAID array is being degraded mode. I am able to access the data, but the web settings will not open. Can anyone please help? I already backed up the data on the old drives, I just want to get the new drives working. I contacted Buffalo tech support and they said "We do not support installing drives of different sizes than were originally installed."

I am really good at following directions, but I don't have much experience with this type of thing. Any help would be greatly appreciated.

Thanks!

Are the WD drives rated for a NAS? I have a Seagate NAS with 2 TB drives and tried to swap in two 1.5. TB drives (also Seagate) that were not certified by Seagate and found that the NAS could not read them. My first instinct is that you are trying to install drives that are not suited for NAS.

Thanks for the comment! These drives are NOT the "red" drives that WD has designed for NAS devices, but I have read elsewhere that they will work. They may just may not last as long... Any other ideas?

There is a limit to the size of drives supported by the bios. Put simply, the system board may not support them. Try to load the latest bios on the NAS. I know on a 1tb unit I have, that worked to increase the size. Check the release notes to see what it fixes.
