fdisk -l does not show the disk... I have bought a new WD 200 Gb disk and built it in a 3.5" Sweex external casing and connected it to my computer with USB 2.0. Is there any way to check if the USB is operational, or to find out what device to use?
I normally plug in the disk - and monitor /var/log/messages
For eg, I get the following after plugging in (on FC1) :
---------------- Jul 10 22:02:05 localhost kernel: hub.c: new USB device 00:1d.7-4, assigned address 2 Jul 10 22:02:05 localhost kernel: usb.c: USB device 2 (vend/prod 0xc0b/0x27e7) is not claimed by any active driver.

The following line tells me the hdd is properly detected - as sda, and there is 1 partition sda1:
Jul 10 22:02:09 localhost kernel: sda: sda1
Now I can format/use the disk.
