Possible corruption on my EFI system partition: how concerned should I be?
by hazel from LinuxQuestions.org on (#4YPTW)
I boot OpenBSD via rEFInd because I don't like GRUB, and because elilo (unlike lilo) doesn't provide a way to chainload the first sector of a partition.
rEFInd scans the partition each time for bootloaders such as Linux kernels. This is considered by its creator, Roderick Smith, to be the optimum way of using it. Yesterday it reported a corruption in the partition but nevertheless found the OpenBSD preloader and ran it.
Just now I booted Slackware and ran fsck.fat on the partition. I got this message, which I don't fully understand.
Code:There are differences between the boot sector and its backup.
This is mostly harmless.
Differences 65:00/01.I was then given the choice of restoring from the backup, making a new backup or doing nothing. Naturally I chose option 3.
In such cases, which is more likely to be corrupt: the boot sector or the backup? Is there any way of checking?
