Re: [Bug-ddrescue] DDRescue me... please..

[Charles Hemingway]

mufngruf:

Since you mentioned that this is an old ibook, I'll assume it's PPC Mac
with a Macintosh bootlabel.  You'll have to look closely when you snag
your partition, the first 6 or 8 are typically Macintosh HD drivers for
OS 9.  Even if you only used OS X on this notebook, chances are the OS 9
HD drivers are in there.

For instance, my primary OS X disk is /dev/sda9 in my PowerBook.  Your
experience may be different, and it may move around when you put it into
another machine.  Also, do a google search for iBook Take Apart, and try
to be specific (iBook, iBook SE, Late 2001 etc). The differences are
important.  Go here if you need clarification: http://apple-history.com/

Good Luck,
Charles
