Oct 28 00:24:50 mb-aw1n-bsd kernel: da0: <SanDisk Cruzer Micro 6.51> 
Removable Direct Access SCSI-0 device
Oct 28 00:24:50 mb-aw1n-bsd kernel: da0: 40.000MB/s transfers
Oct 28 00:24:50 mb-aw1n-bsd kernel: da0: Attempt to query device size 
failed: UNIT ATTENTION, Medium not present

This is on standard 6-STABLE.
