Any one of them by themselves could relegate your images into oblivion. i think the simplest metaphor is to imagine a clock that starts every time you lay a bit anywhere, on a hard disk, an external drive, a DVD, a flash drive. When that clock shows 5 years has elapsed, at least one of those three risk factors is going to be sufficiently elevated that prudence would demand a new generation copy on a contemporary medium and contemporary format. the paradigm is different from the "cool, dry, dark" archive model that worked so well for analog. in digital we need to "stir the bits" by copying to keep them fresh. -rei On 08/14/2011 12:06 PM, Tina Manley wrote: > For those who are not on Facebook: > > *http://www.leica-users.org/NYL<http://www.leica-users.org/NYLUG-2011.pdf>* > *?UG-2011.pdf<http://www.leica-users.org/NYLUG-2011.pdf>* > * > * > * > * > Scary, but true!! > > Tina
