Problem with internal harddrive

[Candyhax]

Hi all.

I hope some of you can help me with this.

I have a PS3 Slim 120 GB - Where I have replaced the hdd with a hdd on 750 GB.
When I format the hdd systeminfo says the hdd size is 698 GB, but only 620 GB is avalible, how can it be?

Best regards, Candyhax.

I'm interested in this too. I've found that the hard drive specifications reported by XBM are inaccurate even on official firmwares.

I got this answer over at ps3hax..

"First of all, remember that HDD companies measure HDD capacity with base 10 mathematics, so that 1,000 bytes = 1 KB, 1,000 KB = 1 MB, and 1,000 MB = 1 GB.
However, the PS3 (along with every computer in the world I know of) measures HDD capacity in base 2 mathematics, so that 1,024 bytes = 1 KB, 1,024 KB = 1 MB, and 1,024 MB = 1 GB.

So, the HDD capacity # is inflated to start with. If you own a 60GB system, you actually have a 55GB system (when measured with base 2, which is what the PS3 uses).

Plus, the OS reserves a PERCENTAGE of HDD space. So, the larger the HDD, the more it reserves."

There is still something wonky going on. Candyhax is saying that the PS3 is reporting a higher than expected hard drive size, but I've seen the opposite.

Additionally, the only part of the OS that is stored on the hard drive is a small (less than 256mb) portion. This does not occur at all on NAND fat models. I think everybody is used to seeing smaller hard drive capacity after formatting. Now as far as the 10 base vs 2 base, are you sure this is the case or are you just guessing?
