Before inserting the media look at the kernel partition table to see
what is already present.
$ cat /proc/partitions
While inserting your media watch the syslog.
$ tail -f /var/log/syslog
Look to see what it says about the device when it is inserted. After
the device is installed and settled look at the kernel partition table
again to see if the kernel has recognized the partition table.
$ cat /proc/partitions
I think it likely that different media with different partition tables
are presenting different partitions and confusing things. Such as
/dev/sda versus /dev/sda1 versus /dev/sda5 or other such differences.
