Neil,

What environment are you in PIC, Windows, Linux, <??>?

How important is it that you don't lose any data.

If on a PIC what filesystem and SD card access code are you using?

Subject: [EE] SD card best practices?

I'm writing ongoing CSV data (logging) to an SD card, and wondering if=20
there are any guidelines for when to periodically flush the data to the=20
card.  Should I flush after every line of data?  Or should I flush after=20
some amount that ties to block-size, etc?  Is there any good doc=20
floating around the web that has good guidelines or best practices for this=
?
