Re: [gentoo-ppc-user] mac-fdisk: Can't read block 0 from file (Is a directory)

[Michael Hanna]

yeah, I did my ABCs but nothing came up :/

you know what's weird...I look in /dev and I see

sg2 - > scsi/host1/bus0/target6/lun0/generic

when I enter

mac-fdisk /dev/sg2

the flashing prompt moves to the left of the screen then........nothing

the only way to get out of it is to press the Apple key, which brings 
me back to the login prompt.
