Hello, This is not an openSUSE specific support request but it's related to a series of error messages I noticed after having cloned my older HDD 512/512 bytes/sector to a newer Western Digital HDD, which uses the advanced format 512/4096 bytes per sector. I would like to avoid that this sort of partitioning may affect the read/write IO rates. The errors I see are these: marco@linux-turion64:~> sudo fdisk -x Disk /dev/sda: 931,51 GiB, 1000204886016 bytes, 1953525168 sectors Disk model: WDC WD10SPZX-22Z Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x5bc53d8b Dispositivo Avvio Start Fine Settori Id Tipo Start-C/H/S End-C/H/S Attrs /dev/sda1 * 2048 1026036 1023989 7 HPFS 0/32/33 63/221/19 80 /dev/sda2 1026037 447673612 446647576 7 HPFS 63/221/20 218/100/23 /dev/sda3 447673613 449516792 1843180 27 Hidd 218/100/24 333/32/12 /dev/sda4 449516793 1953523118 1504006326 f W95 333/32/13 769/48/30 /dev/sda5 449516795 617287136 167770342 83 Linu 333/32/15 536/88/33 /dev/sda6 617287138 1918772938 1301485801 83 Linu 536/88/35 654/23/20 /dev/sda7 1918772940 1953521663 34748724 82 Linu 654/23/22 1023/254/63 Partition 2 does not start on physical sector boundary. Partition 3 does not start on physical sector boundary. Partition 4 does not start on physical sector boundary. Partition 5 does not start on physical sector boundary. Partition 6 does not start on physical sector boundary. Partition 7 does not start on physical sector boundary. I have the original data on the older HDD and I would like to get the best suggestion in order to correct this issue. When I say "better", I mean less effort-cost and safe enough to avoid to lost data on the new HDD if possible despite I have the backup on previous disk. If you prefer you can send me the suggestions by private message. Thanks in advance! Best Regards, -- Marco Calistri Build: openSUSE Tumbleweed 20220523 Kernel: 5.17.9-1-default - Cinnamon 5.2.7
