<div>== Table in "Current HDD Models that Employ a 4k Sectors" ==<br />
<br />
In this section there is no hint about which way/tool is used to find out the ''Reported sector size''. My hard disk information was obtained by:<br />
<br />
# hdparm -I /dev/wd-hard_disk<br />
<br />
I read somewhere that one can also look at ''/sys/block/wd-hard_disk/queue/hw_sector_size'', which reports only ''512''.<br />
<br />
Also, I don't undestand the order of disks in the table (not sorted by ''Manufacturer'', not by ''Capacity'') so I simply added mine on top.<br />

:Update:<br />
# parted /dev/wd-hard_disk print<br />
:also gives me:<br />
Sector size (logical/physical): 512B/512B<br />

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.<br />
<br />
My solution was mounting the disk to / and mounting a flash memory sandisk with a ext4 partition to /boot. During installation, F17 writes 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:<br />
<br />
# chroot /mnt/sysimage<br />
# grub2-install /dev/sdx<br />
<br />
where sdx is the sandisk.<br />
<br />
These take away my worry as sandisk sectors are 512. They are available in the market.</div>Thomasleow
