addPartitionSetMBR and addPartitionSetGPT as well as wipeDisk call zeroStartEnd to get rid of any filesystem or metadata signatures in a disk / partition.
It turns out that 1MiB is not necessarily sufficient to wipe all signatures.
The VMFS_volume_member signature is at "kboff = 1024" (1024 kilobytes offset). vmfs.c.
In my quick grep of util-linux, the only kboff values larger than 1023 are in vmfs.c. (VMFS comes at 2048).
