NAS102 Power light flashing, can't access unit through ReadyCloud
Hi, yesterday my NAS was off (possible power outage?) so I powered it back up but it was not visible on the network and the blue power light was/is flashing (1 short, 1 long). I could not access it ...
There was only one HDD in the chassis when you downloaded the logs, and it doesn't seems too happy:
Model: ST3000VN000-1H4167
Serial: ******2B

So I'd start with that.
You should test this HDD with the manufacturer's tool.
So, I bought two new WD Red Pro 4tb drives (WD4002FFWX). I removed one of the old drives, installed a new one and let it sync. Then I installed the second new drive and let that sync. During this time, I received a ton of alerts stating Bit Rot detected errors that couldn't be fixed. Now, connecting to the NAS is spotty. It doesn't always show up using RAIDar and I can't access a number of pdf files; I receive an error stating the file is damaged. I don't know what to do.
