To me it looks like two drives (dm-0 and dm-1), both with a non-standard partitioning scheme (speculative guess: might be caused by garbage). My usb-pendrive has two drives: 1 the size of a 3 1/2" floppy, and 1 HD-like, and show up like sda and sdb. Out of curiosity: was this usb-device used before, and with what OS? > the first thing I would like to know before formatting is > what is this "dm" disk type? > > looks like this: > http://oss.gonicus.de/openpower/index.php/Dm-multipath-vscsi Hmm, there is "dm" mentioned in /etc/udev/rules.d/60-persistent-storage.rules: > # skip rules for inappropriate block devices > KERNEL=="ram*|loop*|fd*|nbd*|gnbd*|dm-*|md*", GOTO="persistent_storage_end" The word "inappropriate" scares me a bit. What does it mean? Also /etc/udev/rules.d/64-device-mapper.rules: > KERNEL=="dm-*", ACTION=="add|change", GOTO="device_mapper_do" > GOTO="device_mapper_end" > > LABEL="device_mapper_do" > PROGRAM!="/sbin/dmsetup status -j %M -m %m", > GOTO="device_mapper_end" And from "man dmsetup": > NAME > dmsetup - low level logical volume management I have no experience with that. > but here I have no knowledge to help you :-( Idem dito.
