plugging in USB and no disk there

[Jerry Geis]

I plug in a USB disk (4T) disk and dmesg shows me this:

[ 9528.526871] sd 0:0:0:0: [sda] Sector size 0 reported, assuming 512.

fdisk -l /dev/sda
fdisk: cannot open /dev/sda: No such file or directory

ls -l /dev/sda
brw-rw---- 1 root disk 8, 0 Oct 22 10:49 /dev/sda

Why can I not see sda  ???  I am root at the moment.
