Why is the capacity of my device (as reported by many operating systems) different than the capacity that is listed on its label?
All iDiskk products include the total capacity, at an unformatted level, that is stated on the product packaging. For example, a iDiskk 128GB  USB flash drive has a total capacity of 128,000,000,000 bytes at the unformatted level (where 1GB=1,000,000,000 bytes).
 
Definitions of a Megabyte:
1. Operating Systems commonly define capacity as follows:
     - Kilobyte (KB) as: 2 to the 10th power (1,024 bytes)
     - Megabyte (MB) as:  2 to the 20th power (1,024 X 1,024 bytes = 1,048,576 bytes)
     - Gigabyte (GB) as: 2 to the 30th power (1,024 X 1,024 X 1,024 bytes = 1,073,741,824 bytes)
 
2. Disk Drive and Flash Memory Card Manufacturers commonly define a MB as one million bytes (exactly 1,000,000 bytes) and a GB as one billion bytes (exactly 1,000,000,000 bytes).
 
iDiskk Max defines 1 GB as 1,073,741,824 bytes.  Operating Systems define 1 GB as 1,073,741,824 BYTES.
 
Note: Some capacity is used for formatting and other functions and thus not available for data storage.
