I'm not sure that's the reason. The reason is for access time, they want to keep the files concurrent, as in, no scatter/gather. It's a valid reason, but causes problems if you have file sizes that aren't all the same size, or multiples thereof, you waste space, which a reformat will solve. > They used a primitive filesystem that is > about as robust as using toilet paper to make prints on.

But, that is a deficiency in the software, just like DOS and it's file system, that they should fix. Basically, the software is buggy. > I have deleted some images from my Canon DSLRs and "professional" > Lexar flash cards, and these days they do seem to be able to handle it > without trashing the filesystem.

There is no reason that the software should be buggy and the file system should be robust. I would trash a hard disk once a year with Windows NT and far more frequently with earlier Windows versions. Now, W2k seems to not cause any problems...for at least four years now, my machine has not had any file system problems. > Stick with doing things the way the system > assumes they will be done. Well, that's the problem. The system was designed to "work", and it has bugs. So, it isn't a matter of the system assuming anything, it's a matter of finding what's broken, and finding a work-around until they fix it, but my point was, it should be fixed.
