Today I stumbled upon a drive with a part table like
Disk /dev/sdb: 74.5 GiB, 80026361856 bytes, 156301488 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x213f213e Device Boot Start End Sectors Size Id Type /dev/sdb1 * 9 16434494 16434486 7.9G 55 EZ-Drive
Thanks to google I found this manual
with the quintessence that is
dd if=/dev/sdb bs=1 skip=958 count=66 of=/dev/sdb seek=446
Afterwards you see the ‘real’ partition-table.
Hint: It seems that once the Linux-Kernel noticed dos/windows Drive-Mappers itself and did the remapping for us. This was removed somewhere in the early 2.6ties. Some HowTos say the kernel parameter sdb=remap is supposed to re-enable this, but it didn’t work for me.
