I've been playing around with Pocco's Wichita recording long segments of ambient noise with dpa 4061>wmod-ua5>pdaudio-cf>ipaq. No hiccups after 30min, 45min, 60min... The dreaded 2GB limit is in effect, so we'll see how long I can go at 16/44.1. I did notice the record meters slow down after about 30min to the point where you can't really use them for anything other than knowing you have a signal (no peak level, just graphic bars with no metering, although the bar does turn red at the tip where 0 would be). The elapsed time also started going by 2-3 seconds at a time instead of the normal 1 second. I guess the processor &/or video RAM is getting taxed pretty heavily. Upon playback, there is nothing wrong, just visual on the screen when recording. You MUST turn off the screen when recording so you don't bump the stop or pause buttons (the screen will register bumps from your hands etc, not just the stylus). You can also set the buttons on the iPaq to function as record/play/stop/pause/etc. I don't recommend this as they are not protected and could be accidentally bumped.
You must format your memory for large clusters - I reformatted my 5GB Toshiba pcmcia hard drive to FAT32, 32KB clusters. At 512 byte clusters, I got split-second gaps every 8 seconds. Changing to 32KB clusters seems to have solved that problem. (I used a "storage tools" utility to do this - free trial download, nothing in PocketPC 2002 would reformat the drive)
