I want to upgrade a disk o my LS441D, the "old" disk has 2TB, the "new" disk has 4TB.
I thought that I could use the "Dismount Disk" option, but It is disabled, then I choose the "format" option, later I turned off my nas, remove the old disk from the bay and put the new 4TB disk, but the linkstation won't boot, the led continuous blinks white.
If I reconnect the old 2TB disk the linkstation boots normally, but If I put the new disk It won't boot.
The new 4TB disk has no hardware fault or bad block, I can read/analyze/check It on Windows or Linux normally.
Curiously, If I connect the new 4TB disk as an external disk on linkstation, It recognize the disk, then I can format It as GPT and use It as external normally. But If i try to use It as internal, the linkstation won't boot.

How I solve this?

Obs: I tried to use the new disk on the first and second bays, but the same problem happened.
I'm using the most recently firmware (Version 1.86-0.02).
