I have a buffalo linkstation pro duo with 2 x500gb drives in raid 1 mirror. I am almost out of space, I want to upgrade the drives but when I do it leaves the array limited to 500gb even though it is stored on a 500gb drive.
I was hoping I could hook the drives up to a computer & clone them to a bigger drive but I'm having trouble doing this.
Any ideas of the best & fastest way to transfer all data to 2x1TB drives in raid 1? preferably without having to transfer all via ethernet & then transfer back.
You need to add both at the same time and create a new array to use the full 1Tb.
When you add just one it will only use 500gb and even when the second is added it will still be limited to the 500gb space on the first unless (and I don't think Buffalo supports auto-resizing) that after adding the second and before resyncing, you can expand the first drive space into the unused space.
