Speak for yourself on losing one Minidisc. I had that happen once in the 
frog survey. Chris thought a minidisc laying on my desk was blank and 
erased and recorded over it. Actually it had 12 site recordings on it, a 
week's work. Annoying, but my fault for leaving it there next to a stack 
of blank disks. Some data was never repeated.

Since then I've done my field stuff on HHb's disks and use Sony's for 
music and such like. That way it's easy to tell which disks are not to 
be erased.

Nothing is infallible. I expect there will be those who will have to 
learn the hard way about putting all their eggs in one basket. For, if 
you have that huge capacity, I guarantee that eventually you will have 
it full of unbacked up stuff, just waiting to die.

In a the slower periods it can take me weeks to fill a survey disk. 
That's a lot to loose, but a whole season's recording would fit on this 
new stuff. That's a real disaster waiting to happen.

For a number of reasons I prefer to have relatively shorter capacity 
media. Minidisc is a just fine size. I can handle the initial transfer 
and editing in a evening easily.

On the same vein, how many have their only copy on their computer's hard 
disk? Think about coming in tomorrow and the disk will only emit a high 
pitched scream and not mount.

I do use solid state memory cards. For copies of data for my Palm. My 
Palm is a fairly complete field kit of data on Georgia's frogs. None of 
which is original, just copies.
