[olug] Copying a hard drive to USB with dd

[Anthony Kava]

Yes - just be sure the flash drive is reliable and consider ddrescue or use
arguments to dd to avoid it stopping when it hits an error.  If you want to
be sure you have a good copy you can dd/ddrescue to a file on the flash
drive then run md5sum against your old drive and then the file to compare
their hash values.
