Hi,

* file size, or
* size on disk (occupied size)?

* Mbytes = 1.048.576 bytes or
* MillionBytes = 1.000.000 bytes?

The file size is 139mb on computer
I write it on nand flash (many models) and I try to read it again I found 135MB
But when I write it on the gigadevice nand and read it again I found it 139MB and the device will be power on normally

Without knowing anything about HOW you are writing, or reading,it’s hard to say what’s going on.

And, as pointed out, if you’re confusing megabytes and million bytes.
