Package: grub-pc Version: 1.99~rc1-2 Severity: critical Tags: upstream Justification: causes serious data loss
Running grub-install during upgrade to 1.99~rc1-2, the following message is shown: /usr/sbin/grub-setup: warn: Sector 60 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track. Installation finished. No error reported. After that and a reboot, the first patition (FAT32) on the disk where the MBR was installed is unusable. Neither GRUB nor the linux kernel recognize it anymore: [ 7209.380621] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive! [ 7209.396133] FAT: invalid media value (0xb3) [ 7209.396140] VFS: Can't find a valid FAT filesystem on dev sdc1. Looking in an hex editor at an image of it, it turns out that Grub has overwritten the first sector of the partition. (Maybe because of the unusable sector 60?) -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (x86_64) Kernel: Linux 2.6.37-orbiter.x86-64.1 (PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
