BOTH of my Seagate Business Storage 2-Bay NAS stopped working on the same day.

To all who have had this issue. I to used a Seagate Storage 4 Bay Device/Server. Suddenly it stopped working, stopped recognizing my drives. Without any warning. 1 day worked perfectly, next day came to my office, and no response. I thought a disk crashed, but it was the Server OS. Disk were fine. My 4 Bay defaulted to a RAID 0 would not let you select anything else. 

My first suspicion was that it was hit by a hacker however, I had Webroot on this server and it is extremely tight application. 5 years working and never had this issue. I called Seagate tech support. This is what I was told.

There is a temperature sensor on the board. Theyve had issues with them going bad. There is a video on youtube that shows how to replace several parts including this sensor for Seagate Storage Bay devices. You’d have to find a repair shop to do it unless you repair boards yourself. When this part goes bad, the OS prevents the unit from operating and accessing the disk. It comes on, but then defaults to a Red Light, and the Screen shows nothing, no information. Pushing reset, etc. etc, repowering, does nothing. The OS will not let it boot, that is the problem. So you cant mount the Dsk to see them. Because the OS wont run you cannot access the unit by Admin remote desktop login either. 

Depending on your RAID config, Seagate DSK are formatted in a way by Server OS, to be read directly by a SATA disk reader. So, Seagate said I could remove any of the disk and read them in one of these external SATA disk units. I bought one. All of the disk could be read except my main working disk. I have a 4 Bay Storage/Server Device. 

DSK s 1/2/3/4, only DSK 1 could not be read directly. Some how either my IT guy screwed up, which is what I think happened, or, the OS locked out the access as it originally was setup for ADMIN privilege’s. I still think the IT guy messed up because Seagate said it should not matter as long as I am Admin on whatever PC I am trying to access the Dsk from. My IT had bypassed the Server Os Wizard several times, and made changes manually because he was not experienced with this Server/Storage device. This also jacked up my backups, and disk partitions for backup, including jacking my offsite backups. Least to say my IT guy is fired.  

When opening up File Explorer, again all drives were read easily, each partition except DSK 1. So, instead of calling my IT guy, I went to a reputable Networking Company. Explained to them the situation, and they were able to duplicate reading all disk in Windows 10 Pro, like me, except DSK 1. However, they were able to read DSK 1 using a recovery software. Took about 14 hours to recompile the disk into a readable accessible format, but they did it. Owning a business, this was horrifying for me that a well known IT guy could wreck me like this. All this happened the day before Thanksgiving and I had things due for a client by Monday evening. This company was open until normal closing the eve of Thanksgiving and worked over weekend and had me up and running Monday morning. 

If you cannot read or access your disk in these types of situations, take it to a recovery specialist. I was lucky
