I also think some of the drives lie about being 512KB physical sectors even though they are really 4KB. I'm not sure how you find those.
Easy. In hdparm output (copied from what felix pasted here):
Logical Sector size: 512 bytes Physical Sector size: 4096 bytes
Or using /sys: --cut from below to 'sector_sizes' #!/bin/bash -u if ((!$#)); then set $(cd /sys/block; echo sd*) fi printf "%8s %8s %8s\n" "device" "logical" "physical" for dev in "$@"; do read lbs
/tmp/sector_sizes device logical physical sda 512 4096 sdb 512 4096 sdc 512 512 sdd 512 512
sda = 4TB SATAs in RAID sdb = 2TB SATAs in RAID sdc = 68GB 15K-SASsin RAID sdc = 250GB SSD's in RAID -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
