I have a WD 82.6GB internal HDD installed in an external USB2.0 drive bay connected to my computer. Previously, I assume through SCSI emulation, it was considered /dev/sda. Now, for some reason, it's not mounting properly. I have the following command in my /etc/rc.local
mount /dev/sda1 /backup
Now this mount is no longer working. I assume that the device has changed. I grabbed the following out of /var/log/messages:
Jan 29 20:35:27 localhost kernel: usb.c: USB disconnect on device 2
Jan 29 20:35:55 localhost kernel: hub.c: USB new device connect on bus4/1, assigned device number 3
Jan 29 20:35:55 localhost kernel: usb.c: USB device 3 (vend/prod 0xc0b/0xb001) is not claimed by any active driver.
Jan 29 20:35:58 localhost /etc/hotplug/usb.agent: Setup usb-storage for USB product c0b/b001/1110
Jan 29 20:35:58 localhost kernel: Initializing USB Mass Storage driver...
Jan 29 20:35:58 localhost kernel: usb.c: registered new driver usb-storage
Jan 29 20:35:58 localhost kernel: scsi1 : SCSI emulation for USB Mass Storage devices
I'm pretty sure that this excerpt from the log is after I realized that the drive wasn't mounted and unplugged the drive and turned it off and plugged it back in and turned it on.
Now that you have the background info, my question is this: How do I determine what device the drive is? I found it before on a wild guess.
