Corrupted 2GB Nano, can anyone help!

<< < (2/2)

Febs:
The difference is that manufacturers define a "gigabyte" as 1,000,000,000 bytes.  I'll call these "marketing" gigabtyes.

Computers define a gigabyte as 2^30 bytes, or 1,073,741,824 bytes:

1 byte
1 kilobyte = 2^10 bytes = 1,024 bytes
1 megabyte = 1 kb *2^1024 bytes = 1,048,576 bytes
1 gigabyte = 1 mb * 2^1024 bytes = 1,073,741,824 bytes

I'll call this a "real" gigabyte.

So the "missing" space is the difference between "real" gigabytes and "marketing" gigabytes:

2 "marketing" gigabytes/1 "real" gigabyte =
2,000,000,000/1,073,741,824 =
1.86 gigabytes.

Llorean:
The missing space is also the firmware partition, though that's only another 80mb or so.
