Why not just pickup one of those nifty IDE>CF adapters, grab a decent size cf card, and setup the scripts to write directly to the flash device?


that could work, except i'd have to take out one of my hard drives (i have a 2-drive setup)

The tricky bit is ensuring the drive gets set RO before any power-off of the player, as otherwise a possibly lengthy fsck will cripple it at next boot.


The GPS will mostly be running during long, well-defined drives, so I wouldn't mind if I had to manually start/stop the script (as long as it's something I can do from the player menu, ie something in the Hijack menu). This way, the script can set it back to RO before it closes, and then I just have to make sure I close the script before I power off the player.

Supposedly there is a spare 32 meg partition reserved for stuff just like this.


According my revised calculations (this time somewhat based in reality), the NMEA data will come to about 2 megabytes per hour. Not a lot, but when you're talking about 6 weeks of driving, 32 megs won't be enough. On the other hand, assuming I go the path of making a RAM drive for temp storage, even if the RAM drive is only 1 meg in size, that means I'll only need to write to the hard drive every half hour or so (plus right before the script closes). In which case, it doesn't seem like it would be too risky to have the normal data partition set to RW for a couple of seconds every half hour. Does that make sense?
