yarnproof: Thank you for purchasing the Samsung FIT Plus 3.1 USB flash drive. Samsung drives adhere to the IDEMA standard of advanced formatting, which will result in the drive/card appearing as less than the listed size. This is a common industry-wide standard. The amount of space that appears to be "missing" is in fact used by the drive/card for storing firmware, metadata and spare blocks. Your operating system (Windows, Linux, etc.) will also affect the usable space -- different operating systems will use different amounts of space to store their metadata. Consequently, formatted space will always be less than unformatted space. You can look IDEMA up online for more technical details about this standard, which is established by The International Disk Drive Equipment and Materials Association. For additional questions or concerns, please contact Samsung Customer Support. 1) Call: 1-800-SAMSUNG (ask for Memory) Available 9AM - 12AM EST (Mon-Fri) / 9AM - 9PM EST (Sat) 2) Email: samsungmemorysupport@sea.samsung.com 3) LiveChat: https://www.livehelpnow.net/lhn/lcv.aspx?d=34834&ms=&zzwindow=0&lhnid=29783 Available 12PM-6PM EST (Mon-Fri) The Samsung Memory and Storage Community is also a great resource for getting help from Samsung moderators and customers: https://us.community.samsung.com/t5/Memory-Storage/bd-p/memoryandstorage Samsung is committed to providing the best possible product experience, quality, and value, and we are always here to help with any of your questions or concerns. ~ Samsung Memory
