Hello Gruss Olaf, I just used your suggestion to fix a boot problem for my ibook. Thank you! The linuxboot partition "linuxboot" in the MacOS somehow "emptied". I didn't have a chance to run any hfsutil applications to cause the problem... I think the cause had something to do with going into yast2 and configuring the susewm startup as ASCII instead of GRAPHICS. On the very next boot, "linuxboot" was empty, and the system booted straight to MacOS. Thanks again for the fix. Torben Brosten Olaf Hering wrote:

Hi,
After upgrading my kernel to 2.4.2 and running LiLo again I now find I get a macintosh warning every time I boot into mac. The warning says "disk unreadable, do you want to initialize it?", the disk in question is the macintosh standard partition used for booting linux. When I run disk first aid and try to repair it the program says the disk is unrepairable .. here is the output from disk first aid :-

If I initialize the partition will that also erase the data on any other partitions on the disk? If so is there something else I can do to restore the boot partition?
The hfsutils corrupt the hfs partition sometimes. All you can do is:
dd if=/dev/zero of=/dev/hdaXX hformat /dev/hdaXX lilo
This will remove anything on that partition, recreate the hfs filesystem and restore the boot files.
