2、查看硬盘是否有坏道

写道

badblocks -v /dev/sda
正在检查从 0 到 156290903的块
Checking for bad blocks (read-only test): 完成
Pass completed, 0 bad blocks found.

 3、查看硬盘分区

写道

fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x81728172

Device Boot Start End Blocks Id System

/dev/sda4 5132 19458 115075072 83 Linux

 4、查看已挂在分区使用情况

写道

df -h

/dev/sda2 37G 4.8G 30G 14% /
tmpfs 466M 552K 466M 1% /dev/shm
