Hello,
I have the TS-228A, with non hot-swappable 2 bays.
It currently has 2x2T WD red drives in raid 1, but one drive is starting to have some warnings about current pending sectors and uncorrectable sector count.
I would like to replace them with 2x4T WD red drives.
How can I replace them without losing my data? (the qnap only covers hot-swappable cases).
