Why does the Installer/Mkfs keep trashing my Mac OS partition?
This is probably because you have a rather large hard drive (usually larger than 1GB in size) and tried to run Mkfs on a particularly large partition. From Bob Nestor (rnestor@metronet.com): Mkfs has a problem addressing any disk block above a certain point. It only uses a 6-byte CMD for talking to the SCSI Manager which limits it to 21-bits for block address. When it exceeds this is happily truncates the numbers causing them to wrap down to lower numbered blocks. So, it is quite possible that Mkfs’ing a large partition will destroy other partitions on your drive, including the partition map and the driver partition, rendering your drive virtually useless (you would have to re-initialize it). The problem seems to manifest itself only when accessing partitions beyond the first gigabyte of the drive. This problem also occurs in the Installer utility. Fortunately, there is an easy solution: get the latest version of each utility. They are available at: ftp://ftp.NetBSD.org/pub/NetBSD/NetB
