Top Forums UNIX for Advanced & Expert Users "Phantom" overwrite with dd on sda*? Post 302921526 by LinQ on Friday 17th of October 2014 08:27:03 PM

Thanks again, Don.

So, let me get this straight.

We essentially created a file called sda* in a /dev/ folder on the flash drive, and filled it with zeros until there was no more space at the inn (per usual dd practice).

If so, that could explain the constant 1GB output.

However, I saw this over on stackexchange regarding an (unfortunate) use of /dev/sda*
Quote:
I was trying to write an iso to a flash drive. I mistakenly thought that all /dev/sda* are flash drives attached to the system. I wasn't sure how to figure out which was which, so I just unplugged my flash drives and overwrote them all. In retrospect.... this was unbelievably dumb.
( partition - Ignorantly dd'd /dev/sda* - Unix & Linux Stack Exchange )

Realizing the limitation which dd has with respect to output per invocation, how could this have happened?

Thanks again --
