Just got my GeoChron in the mail, put it on the charger like the data sheet instructed for a full charge. once charged I put a formatted (fat16) sd card in and got ready to test.
As the instructions state I have the power off, and standby on. Put the SD Card in, and hit power button to start the test sequence. Here is where I am getting unusual results, the led appears to be flashing through as fast as it can all its color cycles. nothing gets written to the card, and light never stops. I turned it on without the card in it and did get a flashing red light (which I expected) so not sure if the unit is defective, or the SD card is causing something. Can anyone advise? Thanks.
So ended up being the SD card, for some reason GeoChron did not like it, pulled a card from a digital camera, formatted it the same way, and it worked. Posted question prematurely 
So back to the same topic, I am noticing that either GeoChron is very picky about its SD cards, or my ways of formatting them to fat16 doesn’t always work…
First Card was a small 16mb card formatted Fat16 (windows 7 disc format) - Didn’t work
Next 1GB Kingston card Formatted Fat16 (windows 7 disc format) - Works great
Next (new) 2GB Transcend card Formatted Fat16 (windows 7 disc format) - Didn’t work
Same card Formatted Fat16 (mac newfs_msdos -F 16) - Didn’t work
Same card Partitioned to 1 gig Formatted Fat16 (mac newfs_msdos -F 16) - Didn’t work
Same card Partitioned to 1 gig Formatted Fat16 (windows 7 disc format) - Didn’t work
Anyone else have similar issues and any suggestions?
Thanks
It’s your crummy Transcend card that’s the problem. I only recommend Sandisk in my gps loggers. Kingston is not much better.
I agree those cards are not the best(just what I had Around), but the kingston works… just bought a 2gig sanDisk as well. The logger will create the settings file and a log file but the unit is still showing a slow blinking red light. The manual says that this is an indication of a improper formatted SD card. Im sorta at a loss here, tried 6 or so cards and only one works…
is anyone formatting these a specific way with certain cluster, block, sector, or other configurations…
