Hi,
I'm using a CR1000 with an NL115 compact flash module, and a 2 Gb CF card. Data is output to the card using the command
CardOut(0, -1)
When I collect data, I copy the raw data files to a laptop using a separate card reader. Based on the size of the raw data files, and the 'free space' indication from the laptop, it appears that only 920 Mb of space are actually being used on the card. I'd like to make full use of the card to reduce the frequency at which I have to collect data. I've tried two different cards, with the same results. I assume it's something in my CRBasic code. Can anyone suggest how I might make full use of the 2 Gb card? Will manually specifying the table size help? Thanks in advance.
The logger should use the whole card, presuming there are no more cardout instructions in the program.
Please:
a) make sure you are using a recent operating system in the logger (get the latest from www.campbellsci.com/downloads ) - as more recent operating systems use the FAT32 card format which is more efficient in some ways.
b) format the card in the datalogger which should make sure the card is in a format the logger fully understands. (Some PCs/card readers use obscure sectors sizes etc.)
c) when you do (b) using the File Control option in your PC software (Loggernet/PC400) check how much free space is reported in the card after formatting it.
Thanks for your help. I reformatted the card using Loggernet, and now I'm able to see and use the full card. Before, I had formatted the card using the Windows XP utility.
