Hi I have an Asustor 604 Nas with 4 WD Red 3TB hard drives and have a spare WD 3TB green drive. In the last year 2 drives failed big time and now another looks to be failing. Smart has Reallocated sector count value 200 worst 200 raw value 1 and State Bad. Also has Current Pending Sector value 200 Worst 200 raw value 40 and State Bad.
Is it okay to replace it with a green drive. With 20 odd green drives only ever had 1 fail over the years but most reds have failed. I know if it really is failing it is under warranty and good luck sending it back to where I bought from. Others that were completely dead were a hassle getting replaced
