Re: Tool for detecting partition superblocks needed
Hi Benjamin, hi All
Benjamin, firstly Thanks for your effort ..
OK, and the question I was asking is answered: I took a Fedora 9 CD
for ppc, booted the affected machine, and found, Fedora has the tools
one needs for a disk recovery. smartctrl is there, plus dumpe2fs, and
even "less" (which I was badly missing, on the Debian installer, IIRC)
etc. etc. ... Looks nice ...
[note: the German keyboard on Fedora was missing the bar sign ("|")
.. so I chose an "US English" keyboard layout, that had some sign
similar to that .. ]

Could this also be a simple file system damage?
I was hoping it was just something like that, because this hopefully
could be "fixed" with a reinstall, and with a previous low-level
formatting like
dd if=/dev/urandom of=/dev/hda (not being sure whether the syntax is
correct .. )
Oh, and the Fedora smartctrl found (surprise, surprise .. :) a failure on
LBA 76724676 and 76724678, too (please see the old log above) ...
I attach the log made on the broken machine via
smartctrl -a /dev/hda

I've done some backup already for /home on hda6 ... and /etc on
hda7 (the failing partition) isn't that important ...

As I said: smartctrl is missing on the Debian installer, or at least I
didn't find it ...

to "see" in the sense of to "detect" ...
mac-fdisk detected the damaged partition in the Debian installer, IIRC

No, not that easily .. It's a Powerbook5,8: if I manage to remove the
disk from it (there must be instructions somewhere on www) I'll
reinstall a new one. No time to waste, because my old tibook, where
I'm typing this email, is making strange noises already. Looks like
I'm in need of quick decisions, besides working hardware ... :)

a little more than 2.5 years. Still with the same disk installed that was
shipped with the machine ..
Regards, guys. And Thanks
