Does drive scrubbing results in degradation of hard disks health? Model : Ready NAS RN102
Hi Guys, I have purchased ReadyNAS RN102 with 2 * 2 TB WESTERN DIGITAL NASWARE RED HARDDISKS. I USE IT VERY SPARINGLY. The initial configuration was x-raid but re-converted to JOBD to get the storage size of 4 TB. A day before yesterday copied all the data upto 800GB in size from my NAS to my PC. After successful confirmation and CRC vitrification I destroyed the JOBD volume and converted back to X-RAID (RAID1/MIRROR). OBVIOUSLY, the resync was taking a lot of time. However after 30% was done I stared to copy the data from my PC to NAS. I waited till resync process completed 100%. Once resync completed 100% I verified the data. It was all good till here. HDD health was 100%. I then executed hdd balancing and it completed successfully in about 1-2 minutes. Now I executed the drive scrub option which it state to keep the hdd healthy and no data will be lost. It took overnight for the process to complete. I Shutdown the NAS I no longer needed. When I started the NAS back on, I was shocked to see that warning that the drive health is degraded in slot 1. I has received alert on my email as I had configured alert forwarding.
