ReadyNAS 314 - a year of hell and now lost 10years of data!
I bought a ReadyNAS 314 when they were new in the market back in April 2013. I bought it partly because I wanted to safeguard my increasing data storage with redundancy in case of disk failure, and al...
I don't think this looks very good, but this first pass is 10MB reads so it will tend to skip a lot of data when their are read errors. You need to try the other passes to get more data off the disk. Unfortunate that you had two bad disks, but not unheard of. They probably came from the same lot. They were new drives right? Seagate had a contamination problem that caused some early end of life issues a year or two ago.
On a positive note, your problem appears to be the disks and there is a good chance the NAS is fine. It is theoretically possible that a bad controller could do write-longs to corrupt HW crc's and cause the disk to have subsequent read errors, but I've never seen that happen unless we're doing it on purpose to create disks with read errors for test situations :-).
Do have disk smart info for either of the disks you could post?
