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 :- Checking disk "linux_boot". Checking "Mac OS Standard" volume structures. Checking for locked volume name. Checking extent BTree. Checking extent file. Checking catalog BTree. Problem: Invalid BTree Header, 0, 0 Checking catalog file. Problem: Reserved fields in the catalog record have incorrect data, 105, 5 Problem: Reserved fields in the catalog record have incorrect data, 102, 5 Problem: Reserved fields in the catalog record have incorrect data, 106, 5 Problem: Reserved fields in the catalog record have incorrect data, 104, 8 Problem: Reserved fields in the catalog record have incorrect data, 103, 8 Problem: MountCheck found serious errors. Checking catalog hierarchy. Cannot continue. An internal error has occurred. 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? many thanks. -- - ____________________________ - Jonathon Wallen - B,DES College of Fine Arts, UNSW - z2213441@student.unsw.edu.au - jwal707@cse.unsw.edu.au - jonathon@fridge.unsw.edu.au - ____________________________
