Fine.  The system is checking the write enable status of the SanDisk.
Until you put media in it, you'll continue to see those messages.  The
system treats USB card reader/writer devices as though they were SCSI
disks--in this case with removable media.

SCSI tape devices are named "/dev/st0" (ST for "SCSI Tape").  I'll bet
if you do an "mt -f /dev/st0 status", you'll see the tape whirr and get
a status message about the drive and/or media.

Remember, "/dev/sd" = "SCSI Disk", "/dev/st" = "SCSI TAPE", "/dev/sr" =
"SCSI Removable" (CD-ROM/CD-RW/DVD/DVD-RW)
