It looks for the CDFS, and if it does not exist, it just creates it. Wonder what happens if there is no space to do so?
Those 'CD units' that pop up are usually faked by the drive to appear on the USB bus (or equivalent), and their actual contents is in flash memory somewhere, not on disk. They have nothing to do with partitions – if they had it would be easy to get rid of.
There is no technical or scientific reason for the "rounding", simply marketing.
Ever heard of the SI system? It's technical, it's scientific, and its even used for commercial or financial purposes It defines the giga- prefix to mean exactly 10^9, and as it has been around considerably longer that the 'binary' versions, it has quite a bit more weight.
If hard drive manufacturers prefer to use the most established prefix system in the world, why shouldn't they?
Why forensic tool makers do not do the same, I don't understand.
athulin, your comments are always delightfully pleasant. 8)
Your insight is fascinating regarding CDFS. Can you tell us which brand and model you found this information on?
I am aware that much of this is on-drive controller driven, but never came to the conclusion that a partition has nothing to do with partitions . . . 😯
SI, yes, that vaguely reminds me of something.
If the naming of current drive sizes where driven by SI, then drives which tout any GB sizes would be exactly multiples of 10^9 bytes.
But, this is not the case.
I also venture to say that a base 10 versus base 16 "Giga" are not identical.
Ergo, your eloquent and succinct hypothesis may need some review.
And now, I am going to go and image this 80GB drive. That's 85,899,345 920 bytes, not 80,000,000,000 - otherwise it would be a 74.5GB drive. twisted
After all this, the CDFS remains on the drive . . .
