分区时总会显示下面的语句,不知道是本来就这样还是我把分区搞坏了(sda1和sda2是机器自带的分区),有解决方法吗? 
 
fdisk /dev/sda 
 
The device presents a logical sector size that is smaller than 
the physical sector size. Aligning to a physical sector (or optimal 
I/O) size boundary is recommended, or performance may be impacted. 
Welcome to fdisk (util-linux 2.23.2). 
 
这里是分区信息 
 
fdisk -l 
 
Disk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectors 
Units = sectors of 1 * 512 = 512 bytes 
Sector size (logical/physical): 512 bytes / 4096 bytes 
I/O size (minimum/optimal): 4096 bytes / 4096 bytes 
Disk label type: dos 
Disk identifier: 0x00079c2c
