Re: ibook + USB hard drive = yaboot failure
When I got the drive, it had one big FAT32 partition. I just fired up the
debian net install CD and used it to do the partitioning.
Parted shows me this:
/*-----------------------------------
# parted /dev/sda print
Disk geometry for /dev/sda: 0kB - 160GB
Disk label type: mac
Number Start End Size File system Name Flags
1 1kB 32kB 32kB Apple
2 33kB 2033kB 2000kB hfs debian boot
3 2033kB 10GB 10GB reiserfs untitled
4 10GB 30GB 20GB reiserfs untitled
5 30GB 31GB 1000MB linux-swap swap swap
---------------------------------*/
The 10GB and 20GB partitions are / and /home respectively.
Oddly enough, mac-fdisk (0.4a2) won't print the partition table. Instead,
when I type "p" to print the table, it shows the same information as if I had
hit "P" for "print ordered by base address". If I let either of those
options keep printing lines, it will eventually segfault.
Thanks for the help,
Michael
