[dba-Tech] Ghosting an old HD to a New HD

Just a word of caution regarding Stuart's links (which are actually the same
article, reprinted).

The article appears to have been written at least six years ago.  While it
*may* have been accurate at the time (and it does contradict itself), it is
rather antiquated in computer terms: "I wouldn't look for Serial ATA to even
be introduced to the market until late 2001 or even 2002."  So when it
refers to "the last five years" it's talking about the last century!
