Bad track detection method for Ubuntu system disk

Linux and win are different, win under the disk detection tool to catch a lot of, it works regardless of the name from the very same cattle, not the master is * * experts, but the useful is not much. Khan &http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;

Linux, the longest disk detection tool is Smartcontrol (SMARTCTL)

But my mobile hard drive doesn't support smart, so I can only use the pig-flow method.

Cause: Hanging at a certain height of an object, free-fall-like, smashed in the 320G eaget mobile hard disk, the shell is damaged, because the reading and writing operation, so the bad track detection. (Cup!) ）

First umount the mobile hard disk that has been mount

Code:

umount/dev/sd*

To detect:

Method One:

Code:

Badblocks-s-v/dev/sd*1

Method Two:

Code:

sudo e2fsck-f-c/dev/sd*1

Because the disk needs to be tested, so the speed is very slow, in the detection process, do not power off, do not read and write to the hard disk, do not remove the hard disk, not physical damage, not vibration and so on.

The hard drive also pay attention to heat dissipation.

The detection process can terminate halfway, or you can specify that the block restarts

Usage：

Code:

sudo badblock/dev last start

Wait patiently! I 320G moved the hard drive, took 2 hours, 60%, and then in order to write this article, the cup was pressed by Ctrl + C

Luckily you can specify the block to start

When you see:

Pass completed, 0 bad blocks found.

Congratulations!! There is no bad way. If >0, then you also have a cup. Find the software to fix it quickly!!
