Hi,

I got this message about problems with the boot
sectors on my FAT32 disks at startup of Ubuntu.  I
Googled around a bit to find a solution and seem
to have find half a one.

Checking with fsck.vfat gives this output:

     ~$ sudo fsck.vfat -n /dev/sdb1
     dosfsck 2.11, 12 Mar 2005, FAT32, LFN
     There are differences between boot sector and its backup.
     Differences: (offset:original/backup)
       67:30/25, 68:d2/29, 69:17/e7, 70:37/15
       Not automatically fixing this.
     /dev/sdb1: 19853 files, 7448020/9765385 clusters

     ~$ sudo fsck.vfat -n /dev/sdc1
     dosfsck 2.11, 12 Mar 2005, FAT32, LFN
     There are differences between boot sector and its backup.
     Differences: (offset:original/backup)
       67:1b/a4, 68:a6/0d, 69:65/07, 70:78/69
       Not automatically fixing this.
     /dev/sdc1: 60584 files, 1341041/30516299 clusters

The answers I googled up say I should run the
following, but it expects me to choose between
1) Copy original to backup and 2) Copy backup to original.
Which should I choose?  The stuff on one of those volumes is
really important, and I can't cough up the money to get
something to back it up to ATM.

Bear with me; I'm a *language* geek, remember!

     ~$ sudo fsck.vfat -ar /dev/sdb1
     dosfsck 2.11, 12 Mar 2005, FAT32, LFN
     There are differences between boot sector and its backup.

     2) Copy backup to original
     3) No action
