I still use NAS200 because it's simple and does the job. Few days ago I noticed that I can't turn it on. I removed "Disk 1" and I found that there is something wrong with the disk (white smoke is not a good sign). I got another used HDD. I inserted it in Disk 1 slot and nothing. I format the drive -> nothing. I even deleted everything on drive -> nothing. I used another disk -> nothing. Than I inserted Disk 2 into slot for Disk 1 and I got the message that Disk 1 is Changed. In information table I see Disk with the name, but for other slot there is always Removed and Not installed. I tried and pressed the reset for 2 seconds, but it doesn't help. Can you give me any advice what can I do? I don't know how to get any other disk be recognized. I use RAID 1. It still works, but I just can't get another HDD to work. Any idea?
