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 --

JAZIP.CONF(5)							File Formats Manual						     JAZIP.CONF(5)

NAME
jazip.conf - jazip(1) configuration file. DESCRIPTION
The /etc/jazip.conf file lists the Jaz and Zip devices that users are allowed to mount and unmount using jazip, along with the mount points used by jazip for each device. If you have more than one drive on your system, you can create a separate entry in the configuration file for each one, and then specify the raw device name of the drive you want to use on the command line when you invoke jazip. If no device name is given on the command line, jazip will use the settings in the first entry of /etc/jazip.conf by default. FILE FORMAT
The format of the jazip.conf file should be mostly self-explanatory. Each line looks like: /dev/sda /zip auto auto 0 0 The first entry is the raw SCSI device name of your drive (e.g. /dev/sda without a partition number ). The second entry is the mount point you wish to use (e.g. /zip ). The additional entries: auto auto 0 0 are required but are not user-changeable. They are required because jazip uses standard system call to do mounting and they expect this format. The type of filesystem (e.g. vfat or ext2 ) will be automatically detected by jazip and is not listed in /etc/jazip.conf. CONFIGURATION SCRIPT
See the jazipconfig(8) man page for specifics on the jazipconfig command that you can use to create /etc/jazip. SEE ALSO
