SD Memory Card Formatter

I did not know that there is an official utility to format SD/SDHC/SDXC cards: SD Memory Card Formatter

There are no more details on how this formatting is better than formatting with OS or a mobile device. At least the cluster size is chosen automatically. In earlier versions there was the "format size adjustment" option. In the latest version it is enabled by default.

The "CHS Format Size Adjustment" option is available in the Windows version only. And only for cards with the user capacity not exceeding 8422686720 bytes (255 heads x 63 sectors per track x 1024 cylinders x 512 bytes per sector).
