Thanks for catching the error. If needed, I will use this > command as you suggested:
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.
