I am worried that my server hard disk crash and will not be able to get a 512 Sectors hard disk from the market. Recently, I went shopping for a new disk. All new disks from Western Digital and Seagate have AF (advanced format) label. I bought Seagate 2TB, model ST2000DM001. Its date of manufacture is May 2012. No luck, it is 4096/4096 logical/physical. Fedora 17 can be installed to it but cannot write to its MBR.
My solution was mounting the disk to / and mounting a flash memory sandisk with a ext4 partition to /boot. During installation, F17 wrote boot sector to mbr of / disk. To write to mbr of /boot disk, use F17 to rescue. The following commands were used to write to mbr of /boot disk:
- chroot /mnt/sysimage
- grub2-install /dev/sdx
where sdx is the sandisk.
These take away my worry as sandisk sectors are 512. They are available in the market.
