i have baught a new HD with same size and capacity. and trying to copy partition via command "sfdisk -d /dev/sda | sfdisk --force /dev/sdb"
above command work well. however one confusing part it "fdisk -l /dev/sdb" is giving some information which i am worried about. i think it souldnt give me this error as the harddrives are same specs and even vendor is same. can anyone kindly share why it is giving me this message. should i worried about the stability of my raid as it is going to be in production soon and i do not wanna loos my data. here is the detail .
