swamiforlife Posted January 17, 2020 Share Posted January 17, 2020 Hello, I have a 24 drive array with 2x 10TB parity disks. Total size of array is 188TB with 132TB used. I have 2 disks with bad sectors, 1 is a 6tb and the other is a 10TB drive. Since my array is very large and it takes a long time to do a parity check. Is it better that i copy off the data from each bad disk replace the disk and copy the data back on or should i let Unraid do a rebuild? I want to minimize the downtime for my array as its used for nightly backups. Quote Link to comment
