找到这个了,可惜里面没有我要的信息

我更想找那些启动时显示的

后面带有[OK]的那部分信息

那样我就可以找到一部分faild的了

和楼主一样的情况,fsck取消 一切OK了,启动也快了不少
只是不知道他这个检查是不是代表我的磁盘有错误?
win下磁盘扫描没发现什么啊

去掉win分区的检查

你用过win, 分区就变了, fsck认为有问题

When there are 'differences between the bootsector and its backup'
If there is a Windows file system present in the machine, it usually has an entry in our /etc/fstab file made automatically when Ubuntu is installed. That means it will be automatically mounted during each boot-up.
Ubuntu needs to check other file systems during boot-up to make sure they are in a fit and safe condition to write to, especially if they are to be mounted 'read/write'. A disaster could result if an attempt is made to write data to a file system already has some kind of small problem.
The file system check is turned on by a number in the 'pass' column in our /etc/fstab file.
Windows and other file systems would normally have a '2' in the 'pass' column so fsck will check them in parallel with any other file systems to save time during boot-up.
You can change the number in the 'pass' column from '2' to '0' if you don't want Ubuntu to check your Windows file system at all, but I do not recommend that.

The first sector of a Windows partition is known as the boot sector.
Malware and viruses like to alter the code in a Windows boot sector so the malware or virus will be booted when Windows is booted, and/or to show you an ad as soon as your Windows computer boots.
Another way to destroy a Windows boot sector would be by installing GRUB to it by accident.
(GRUB should be installed to MBR, or a Linux bootsector, but not to a Windows bootsector).

Fortunately, in Windows with the FAT32 file system, there is a backup bootsector which can be used to restore the original bootsector.
I don't imagine there would be any Linux command you can use to fix the boot sector of Windows with the NTFS file system. It is only recently that Linux NTFS support has made NTFS safely writable from Linux. You would need to use FIXBOOT from a Windows recovery console.

For Windows with the FAT32 file system you can do this in Ubuntu with a 'sudo' command. Make sure the file system is unmounted first, then use 'sudo dosfsck -ar /dev/hdx,y', or 'sudo fsck -V -r /dev/hdx,y'.
WARNING: First try scanning your Windows system for viruses and malware with as many anti adware and anitvirus apps as you can get your hands on, as they may can your bootsector and find the virus by recognizing it's code in your bootsector. Replacing your boot sector with it's backup right away might not be the best idea. You really need to get rid of the virus first.

For a different opinion about this error message and how to handle it, see this Ubuntu forums thread Not automatically fixing this and in particular take note of what ncdave4life had to say in post #10. That seems to make sense to me too, and would likely be perfectly correct, if you have more than one version of Windows this error message might not be anything to worry about.

The example I will give here will fix your Windows FAT32 boot sector if you have accidentally made a mistake with the grub-install command and installed GRUB to the wrong partition.

It is best to use a Live CD for this type of work, so the file system won't be mounted.
In this example I used a GParted -- LiveCD.
如果是用Ubuntu Live CD那么,
修复命令:sudo dosfsck -ar /dev/hda1#我的是sda1,依你的情况而定。
或者:sudo fsck -V -r /dev/hda1
Where: /dev/hda1 is a FAT32 file system partition. (Not NTFS).
After entering either of these commands, the program will show you a report, so you can see for yourself what the differences are.
Normally, the report would not be as large as the one shown here, and would only show a few bytes where the differences were found. This example was obtained by installing Grub to the FAT32 bootsector, which is not a recommended thing to do. (Don't try this at home, folks!).

root @ Parted # sudo fsck -v -r /dev/hda1

1) Copy original to backup
2) Copy backup to original
3) No action
? 2


You will be offered a choice of the following actions,
1) Copy original to backup
2) Copy backup to original
3) No action
?
You type the answer after the '?' prompt.

You should be careful here. Most of the time I think it would be the original (the bootsector that is in use) that would be corrupted. In that case 99% of the time I would suggest typing a '2' so the bootsector will be restored from the backup copy.
However, there was a thread recently in Ubuntu Web Forums where it was the backup that was found to be corrupt for some reason, and the user fixed it by typing '1' instead.
Most of the time it should be '2', but be careful.

Then, it will ask you to confirm,
Perform changes ? (y/n)
I suggest typing 'Y' here.
That's it, it should be fixed!

也可以使用windows安全模式下运行FIXBOOT
当然如果win中毒而破坏了引导区数据,最好清楚它的办法就是“重装win”不让病毒再来。
