Stack Smashing Detected

I haven’t run into this fancy little kernel output before. While automating the writing of partition tables and file systems to removable storage devices, I thought i’d test the case of trying to write to a read-only file system.

$ sudo /sbin/parted /dev/sr1 mklabel msdos

I hate SanDisk Cruzer thumbsticks and their silly little U3 partitioned device. This error comes from trying to write a partition label to /dev/sr1 which is a device with a read-only file system.

———-sudo /sbin/parted /dev/sr1 mklabel msdos
