Here's 'fdisk -l'. (sdb is a usb disk I connected later.) The warnings
seems to corroborate cinap's comment, is it so?
The dump: http://dl.dropbox.com/u/10125317/sda.16.dump
(dd if=/dev/sda of=sda.16.dump bs=4096 count=16)
That should be the 1st. 16 sectors I hope. I checked (dumpe2fs) the bs of
sda3 (this partition is intact) to use the above bs. Also, to boot into my
Windows, I had fixed the mbr using the Windows 'fixmbr' command. So you
will find an intact mbr, and therefore not a very useful thing, the dump
will turn out to be.
This exercise is turning out to be interesting. May I ask how you would
have worked on the dump, and what could be learnt from looking into it?
And what did you mean by : cat /dev/sd*/ctl, it didn't work for me? I used
sda and sda5.
