> So what do you propose as a solution ?? solution? strictly differ between decadic and binary prefixes, so use k for 1000, M for 1000000, G for 1000000000, while Ki for 1024, Mi for 1048576, Gi for 1073741824 so if a HDD manufacturer speaks about 20GB HDD, count it as 20 000 000 000 B, so you won't be surprised it is not 20 GiB. > Maybe I'm dense, but; > kb = kilobit = 1000 b > KB = KiloByte = 1024 B > mb = megabit nope, small 'm' snands for 'mili' which is 1/1 000 000 e.g. one millionth part. > MB = MegaByte megaByte, actually 1000000B, but is ocasionally used > 1 bit * 8 = 1 byte > 1 Byte / 8 = 1 bit yes, usually. the Byte was first defined as the smallest amount of data a CPU can ordinadily work with. currently, it's being used as "8 bit", however there were compurers that used e.g. 9-bit Byte. > Serial ATA (SATA) data transfer rate specification = 1500 *mbps* or > *mb/sec* (megabits per second). 1500 / 8 = 187.5 *MBps* or *MB/sec* - as I again say, small 'm' means 'mili' so it's not correct > > Luckily, HDD manufacturers count with KB/KiB (1024B)'s, so 10GB HDD was > > counted as 1 000 000 KB - 1 024 000 000 Bytes.

I think not.... > Why would I want to divide sectors anyway. what I meant, was that it would be even worse if they multiplied number of sectors by 512 and divide by 1000 to get some more of "fake" capacity... -- Matus UHLAR - fantomas, [EMAIL PROTECTED] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
