To prevent inaccessible data, keep the pictures on your hard disk and copy
them to the new disk when you upgrade. Keep backups, preferably offsite
(safe deposit box). Why? Here's a few reasons: 8 in. floppy; single sided,
single density 5.25" floppy; casette tape; MFM (ST506?) hard disks; magtape;
double-density CD-Rs.
To prevent inaccessible data formats, first pick one that has a good chance
of lasting a while (I like JPEG because of how common browsers that can read
that format are). Assume once in a while you'll need to translate all the
images into a new format. Here's a good reason: Amiga HAM format.
Do I do this myself? Not a chance -- I can't afford the disk space either
:-) I save my images on CD-R media in TIFF and JPEG format, _and_ save the
original slides, and still I hope for the best.
I recently found that not even CD-Rs are safe.. that is when I went looking
for an image I wanted to submit for PUG, only to find a corrupt TIFF and
unreadable JPEG (the original TIFF and JPEG on my disk were not corrupt when
I made the CD). Seems somewhere the data that was being written to the CD
got corrupted (I think, before it was actually written as there were no read
errors, just corrupt files). I need to rescan the slide. That, and find a
bulk diff program that can compare the data on the CD with the original
files before I delete them off my disk.
