First time getting a disk failure and need some guidance

[hsynneva]

Hi,

 

Just found out that my Unraid sever gave some notification errors about a disk with bad sectors.

This is my newest disk that I added to my array a month ago. Ran preclear and it gave no errors at that time.

 

I appreciate if someone could guide me on what the next correct steps would be when encountering such issues as this. 

 

Thanks!

Disk dropped offline so there's no SMART, check/replace cables and post new diags after array start.

Thanks for the reply.

 

Ok so I did shutdown the unraid and checked the cables, then replaced the cables with a brand new just to be sure.

Now it just reports disk5 "not installed". I'm assuming the disk died... Will test it on another computer to verify that.

 

Is my next move to buy a new disk for replacement? How does that work, will the parity disk rebuild disk5?

Since the disk didn't show up after a cable change it might have died, might be worth swapping both power and SATA cables with another disk to double check, if the same get a new disk and assign it to that slot, emulated disk is mounting so you just need to rebuild.
