How can I delete or completely erase a partition-table.
The feature "delete partitiontable" is removed in the opensuse partitioning tool.
Thanks, Hans
The typical PC partition table is in the very first sector of the drive, so:
dd if=/dev/zero of=/dev/sdx count=1
should do it, but you may need to reboot to get the kernel to reread it. ...
The kernel manages all I/O (even when you access a disk via its /dev entry, not just via files), so any buffered disk blocks it has will remain consistent when you write.
True, but irrelevant. The kernel maintains a list of partition tables in ram. (/proc/partitions) Doing behind the scenes updates to /dev/sdx has no impact on those ram based tables. Try it. cat /proc/partitions dd ... cat /proc/partitions You have to tell the kernel to update its tables from disk after you update the disk. I just don't remember how to do that offhand, so I said a reboot will definitely do it.
