    Hi,
    I want to use a HDD to log data. I need to connect it to an AVR. Any
    one have idea how do this?

  2. Download the manufacturers datasheet. Then connect it
    to the AVR according to the datasheet. Then have the
    timing of the signals according to the datasheet.
    Then have a look at the command set. Now arrange the
    commands to format the disk, read and write to it.
    Yes, a filesystem ... perhaps FAT16 with 65536 allocation
    units, each at least one sector.

    Those people are selling a flash chip on a stick.

    The OP was asking about an HDD. I presume that means "Hard Disk Drive".
    I'd just look up the IDE spec. From what I've heard, it looks like a big
    memory array. (IDE == "Intelligent Device Interface")

    For example:

    second hit at
    http://www.google.com/search?q=IDE+interface+spec

    Good Luck!

    Besides the most excellent answers you receive here, you might want to
    try the computer storage group as well.

    comp.sys.ibm.pc.hardware.storage

    Good luck.
     

  6. You'll have to gather some information. Google for "ATA" to find the
    interface information you need. Google for "Commodore 64" and "hard disk" or
    HDD to find at least one example. No need to say you need the datasheet of
    your AVR as well.

    You may want to take a look of the YAMPP schematics and sources:

  8. No, he'd sell "flash sausages" on a stick.

    His product range includes rat-on-a-stick for dwarves and something else
    for trolls, so why not chip-on-a-stick for EEs?
