I tend to think of pictures and movies as sui generis--they were 
perfectly well done in non-digital form, so I don't include them as 
"data" needing backup, but rather a special case of digital data 
masquerading as a simulacrum of analog information.

Anyone remember the IBM "Photostore"  setup at Lawrence Livermore? 
Enterprising programmers wrote tools to go through their files and 
"touch" them, lest they be "Photostored".  In many cases, that meant 
"gone forever".
In the case of spinning rust, what brand is most reliable?  I've seen 
dreadful reports of DOA drives from Western Digital, fewer from Seagate, 
but I don't know about Hitachi, Samsung, etc.

Up until now, I've confined my purchasing to 500GB drives on the hope 
that they're more reliable than the 3-5TB monsters.  Is this a mistake?

FWIW, my SA-4004 still works...
