Faulty Chassis?

Question

I have a NAS 314 that my co-worker let me keep, it was no longer being used, so I decided to set it up at home as a media server.

I initially installed two existing Seagate drives (250 GB each) that I removed from a desktop computer, and everything was working fine - they were installed into bays #3 and #4.

So I then purchased two more Seagate Ironwolf 4TB drives to put into the remaining two bays. I didn't know that I could access the logs until several days later of waiting for them to finish syncing, but it seems that the drive in Bay #2 was giving me problems - the LED light over bay #2 was flashing so I discovered I could see the logs from my admin page - it was giving me an ATA 20393 error, I did not know what the error meant but it lead me to believe its either the drive or the NAS controller unable to communicate with the drive.

I chose to replace the suspect drive in Bay #2 with a brand new one, and the same thing happened in the same bay.

So now I have removed the two 250 Gb drives, replaced both of them with the new 4TB Ironwolf drives into bays #3 and #4, and everything is fine now. Bay #1 and #2 are still empty.

My question is, can I repair or replace the chassis for Bay #2? If so, where do I find such a part?

thanks

FIrst, I would power down the NAS and move the drives into slots 1 and 2.&nbsp; Then power up, and see if the NAS boots properly.&nbsp;&nbsp;
&nbsp;
If it does boot, you can go to the volume page in the web ui, click on the volume settings wheel and run a disk test.
&nbsp;
If it is the bay, then it's not easily repairable.&nbsp; Netgear doesn't sell parts, and there is no service manual.

An ATA error, though recorded in the drive SMART data, can be caused by a problem with the interfacing hardware, not the drive itself.&nbsp; Failure to fully seat is often the issue, so look inside and see if there is anything restricting the drive or the connector is broken or dirty.&nbsp; If you see nothing, then the fact that it occurred with two new drives that work in another slot suggestes it is a chassis issue -- probably the SATA backplane.&nbsp; &nbsp;Spare parts are not available, even for original purchasers.&nbsp; So, be happy you have a free 3-bay NAS.

Thanks,&nbsp;Sandshark - I will inspect the connector and cross my fingers it is just dirty.... the NAS has sat unused for a number of months prior to my attempting to get it set up.&nbsp;Quentin&nbsp;

thx&nbsp;StephenB&nbsp; and&nbsp;Sandshark&nbsp;&nbsp;turns out it was dirty: I powered down, blasted with air and installed all four disks into the bays before booting again, and it worked!all green LEDs across the board.&nbsp;So now I have another question, I put the two smaller drives into bays #1 and 2, but they have data on them from the last time I created the NAS volume.&nbsp;What if I want to start over from scratch, ie: use the two small drives for one volume and the two larger drives for another volume? how do I do that?&nbsp;thx again

&nbsp;

If you want two volumes, you would turn off XRAID on the volumes page.&nbsp; If the green stripe is on the XRAID control, then XRAID is enabled.&nbsp; Click on the control, and it will turn off.
&nbsp;
Then hot-insert the two other disks.&nbsp; You'd select them, and then format.&nbsp; After that you create a second RAID volume.
&nbsp;
The other option is to just leave XRAID on, and go with a single volume.&nbsp; You'd get more capacity that way.&nbsp; You'd hot-insert them (as above) and format them.&nbsp; The NAS should then begin adding them to your existing array (one at a time).&nbsp; The capacity rule is "sum the disks and subtract the largest".&nbsp; Keep in mind that the NAS reports volume size in TiB (1024*1024*1024*1024 bytes), but the disk manufacturers use TB (1000*1000*1000*1000).&nbsp; Google will convert for you - try entering "10 TB in TiB" into google search.
