How can I determine which /dev/sdX device my usb stick is plugged into?
I am running Ubuntu 9.04.
You may want to use
/dev/disk/by-uuid/ instead. These never change for a given device, whatever
/dev/sdXX your pluggable drives have.
sudo blkid : it will show block device names:
/dev/sdc1: UUID="004A31DB4A31CDE2" LABEL="WinGamer" TYPE="ntfs" /dev/sdd1: LABEL="0DAY" UUID="9b14c03b-7251-434f-bbb9-eac42b2db927" TYPE="ext2" /dev/sdg5: LABEL="QFAT" UUID="4257-E346" TYPE="vfat" /dev/sdg6: LABEL="BACKUP-HDD" UUID="fee45c66-11bd-49fa-a62a-4a541716e8e1" TYPE="ext2"
on a command line, do a
ls /media and you will usually see it.
e.g. on my system:
$ ls /media cdrom cdrom0 cdrom1 floppy floppy0 LaCie
LaCie is my usb stick
failing that try
on my system
$ lsusb Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub ... Bus 001 Device 004: ID 059f:1028 LaCie, Ltd ...
If it shows up there but not in /media, you will need to figure out mounting, or ask another question..
Finally, I can type "mount" and look through the output for your answer, or in my case:
$ mount | grep LaCie /dev/sdb on /media/LaCie type vfat (rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)
It will depend. Type
dmesg at the console and the output should show the USB stick being mounted.
Here is some example output:

In my case its the
sdb device that is assigned after I plug in a USB stick, since I have just the one internal hard drive in my laptop (sda).
