Why does my 256GB SD card only have 238GB: The discrepancy arises due to different measurement systems used by manufacturers and operating systems. Manufacturers use decimal (base 10) where 1GB = 1,000,000,000 bytes. However, computers use binary (base 2) where 1GB = 1,073,741,824 bytes. This difference leads to less available space when viewed through the operating system. Additionally, some space is utilized for the file system and formatting, further reducing available capacity.
FAQs & Answers
- Why is my SD card's available space less than advertised? The available capacity differs due to manufacturers using decimal measurements and the operating system using binary, plus some space is reserved for file system overhead.
- How can I recover lost space on my SD card? You can reformat your SD card, but be sure to back up your data first, as formatting erases all content.
- Is there a way to increase my SD card's storage capacity? There's no way to increase a card's physical storage, but you can manage files better or use cloud storage as an alternative.
- Why don't I see the full capacity of my SD card in my camera? Cameras may have their own file system considerations that can further reduce the visible space.
