I just looked at what you posted earlier, and realized that it didn't
give a count= parameter. So, the command you gave earlier would
actually erase the entire drive one megabyte at a time instead of 512
kilobytes at a time, which I believe is the default block size dd
uses.

So, to clarify,
dd if=/dev/zero bs=1M of=/dev/sdx
would in fact erase the entire drive. Apologies for the confusion.
