Hello reading the other thread about advantage of 4096 sector size disk, I noticed one of my (spare) 1Tb backup disk is given by hdparm to have 4096 sector size, and I wanted to use it. however I'm puzzled. what ever I do, hdparm always says logical 512 / physical 4096, fdisk and YaST 512/512 first tryed with yast, modifying the filesystem option to 4096, then tried manually with: fdisk -b 4096 /dev/sdp remove partitions, create new as default -hole disk), write disque /dev/sdp : 8001.6 Go, 8001639088128 octets, 1953525168 secteurs Unités = secteur de 1 × 4096 = 4096 octets Taille de secteur (logique / physique) : 4096 octets / 4096 octets but hdparm says: Logical Sector size: 512 bytes Physical Sector size: 4096 bytes and fdisk -l Disque /dev/sdp : 1000.2 Go, 1000204886016 octets, 1953525168 secteurs Unités = secteur de 1 × 512 = 512 octets Taille de secteur (logique / physique) : 512 octets / 512 octets so what? thanks jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
