Overriding EEE PC’s drive letter assignment for USB devices
When you plug a USB device into the EEE PC, it makes it look like it has a Windows drive letter by mounting it on something like /media/D: This is fine for a lot of stuff, but I have a USB drive I want to put a VirtualBox virtual machine on, and I don’t want to take the chance that it will be drive E: next week.
So, I made a change that seems to work: I created a file called /etc/udev/rules.d/01-local.rules that overrides the default usb handling just for this device (or devices just like it; I’m not certain that this uniquely identifies a particular device). Put this all one one line:
BUS=="usb", KERNEL=="sd*", SYSFS{serial}=="P975LEG4", NAME="VMs",
OPTIONS+="last_rule",
RUN+="/bin/mount UUID=5cc6f807-0ee2-46a8-a48a-90a2b9b1ab22"
To make this take effect, I make sure the device is unplugged, the run the command sudo udevcontrol reload_rules. I make sure I have a mount point for this device in fstab (and that the mount point exists):
UUID=5cc6f807-0ee2-46a8-a48a-90a2b9b1ab22 /mnt/VMs ext3 auto,users 0 0
Now, when I plug the device in, it doesn’t get a DOS-ish drive letter, no window pops up asking me what I want to do, and it gets mounted where I want it. I still have to umount it when I’m done, but this is progress. How do you find out the serial number of the device? Assuming that it’s recognized as /dev/sdd, you can use:
udevinfo -a -p /block/sdd
You can use the blkid command to get a list of all drives and their UUIDs.
