Comment 13 for bug 96976

What more information do you need?

lspci and lsusb have nothing to do with the problem, nor does the disk type or settings.

Most people who have this problem don't have this problem for very long because they fix it; but you can reproduce the problem on any PC like this:

sudo sfdisk -d /dev/sdX | tee ORIG.$$ | sed 's/^\(.*start= *\)\([0-9]*\)\(.*\)/\1 63 \3/' | sudo sfdisk /dev/sdX

and produce an overlapping partition table by making all partitions start at position 63.

In such a case gparted wrongly shows that there are no partitions.
