I got the following message during boot process:


There are differences between boot sector and its backup.
Differences: (offset:original/backup)
  430:4e/44, 431:54/61, 432:4c/74, 433:44/65, 434:52/6e, 435:20/74, 436:66/72
  , 437:65/84, 438:68/67, 439:6c/65, 440:74/72, 441:ff/20, 442:0d/65
  , 443:0a/6e, 444:4d/74, 445:65/66, 446:64/65, 447:69/72, 448:65/6e
I did several times to fix this problem by using fsck, but always fails. The reason is that I forgot to use -ar options. Without this options, the file systme is not repaired. I found the man page of dosfsck as follows:
 If -a and -r are absent, the file system is only checked, but not repaired.

Anyway, dosfsck -ar /dev/hda1 solves the problem.

오랬동안 계속 되던 메세지인데 고쳐도 고쳐지지 않았었다. 반드시 해결을 하고자 여기저기 찾아보니 맨페이지에 -a 혹은 -r 옵션을 주지 않으면 고쳐지지 않는다고 나와있었다.

dosfsck -ar /dev/hda1
