Really? Even ATA flashcard manufacturers? So now I have to know if CF-card has spinning parts to decide size?
What makes you think so?
Looking at a flash card here (sold as 8 MB), I see
SCSI device sdb: 15872 512-byte hdwr sectors (8 MB)
Now if the manufacturer claimed 8 MiB I could sue him, but since he only claims 8 MB, this one is large enough (it has 31 . 2^18 = 8126464 bytes). It is 8.1 MB and 7.75 MiB.

Always remember: (i) k=1000, M=1000k, G=1000M (ii) specifications are rounded down, so that customers cannot complain (iii) if something exists only in power-of-two sizes, that helps guessing the actual size; however, this is not true for disks, and as this example shows, it is not true for CF cards either. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
