[TriLUG] USB memory key, removal, IO errors

[Frye, Matthew]

After I umount my usb key, I receive IO errors when I pull it out.  See
below:

Mar 25 11:14:17 hermes kernel: usb.c: USB disconnect on device 00:14.2-2

Mar 25 11:14:17 hermes kernel:  I/O error: dev 08:00, sector 0
Mar 25 11:14:17 hermes kernel:  unable to read partition table

Is there a step I am missing?  Perhaps something I "should" be doing before
I yank 'er out of the usb port?  I just don't like to ignore errors.
