  1. Are you sure you want fat16. It only supports partitions up to 2 gig.

    You would be better off using fat32. You should be able to right-click the drive and select format. You will be restricted on how large a partition to make using the vista formatter. You can use a utility called fat32formatter that will allow larger partitions. I've used this before and it worked fine.

    :bounce: Hello and thank you for your help. Yes. FAT16 is all I need for a 2GB SD Card.
  3. :bounce: Yes. FAT16 is all I need for a microSD Card. So my question is how do you format an microSD card? Any suggestions would be appreciated. Thanks
  4. According to this, windows displays fat16 as just fat. I'm assuming you have a card reader for your computer.

  7. Hi nerdgirly -

    I'm going to proceed on the assumption you want to know what you asked rather than advice on how and why to do something different...

    That said,
    1. open a dos window (run CMD or search and double click CMD) and type format <D>: /FS:FAT (replace <D> with the drive letter of the SD and no < >'s) - this should work for any version of windows released in the last decade.

    or 2. Run DISKMGMT.MSC in Windows7, Vista, or XP, scroll down until you see the SD drive (probably the last one in the list), right click on the drive letter ( or anywhere on or under its blue bar), right or left click format from the list and select FAT for file system and click OK
  8. Download SDFormatter from https://www.sdcard.org/downloads/.
    This will format to proper FAT16. Not sure what Windows is doing, but it's not pure.

    Didi download the above. Page 9 of the installation manual shows the completed memory card format as having file system FAT32. This is what I got, but I want FAT16. Where am I going wrong?
