Hi,
i just bought some WD20EARS harddisk. They are supposed to have 4k physical sector size, right?
My system seems to think they are not:
alex@hal:/sys/block/sdb/queue$ cat logical_block_size physical_block_size
512
512
alex@hal:/sys/block/sdb/queue$
alex@hal:~$ uname -a
Linux hal 2.6.33.2 #1 SMP PREEMPT Sun Apr 4 20:52:14 CEST 2010 x86_64 GNU/Linux
alex@hal:~$
from dmesg:
scsi 1:0:0:0: Direct-Access ATA WDC WD20EARS-00S 80.0 PQ: 0 ANSI: 5
sd 1:0:0:0: [sdb] 3907029168 512-byte logical blocks: (2.00 TB/1.81 TiB)
so, who is right?
The current partition table looks like:
alex@hal:~$ sudo cfdisk -P s /dev/sdb
Partition Table for /dev/sdb
First Last
# Type Sector Sector Offset Length Filesystem Type (ID) Flag
-- ------- ----------- ----------- ------ ----------- -------------------- ----
1 Primary 0 3907024064 63 3907024065 Linux (83) None
alex@hal:~$
is that okay for 4k sector size?
Alexander
