750 Gig SATA HD showing as 698

Sellingen · 03-21-2008, 05:44 AM

I recently built a computer and I'm having a couple of problems already. I have two seagate barracuda SATA hard drives. One is 160 gigs, the other is 750.

The 160(the drive with windows on it) is showing up at about 150, but the 750 is showing up as 715,402 MB, or 698 gigs(i found a conversion chart online, not sure how accurate it is). I usually expect to be off by 5 or 6 gigs, but near 50 seems kind of odd.

When I go into my bios they are both recognized at their full capacity. Am I just kind of out of luck with the 750 gig one, or is there something I can do do get closer to 740 or so?

The second problem is that when I boot up my computer, for a split second or so on screen it will say "No hard disk is detected" or something along those lines. it boots up fine but I can't help but think that that may be part of the reason for the other drive showing up at 698. These are both separate, by the way, I don't have these set up as a RAID (kind of a newbie at this, wouldnt want to attempt it)

I'm working on updating the bios, so I'll see if that fixes anything. I did my best to look through the threads and find a solution, but as I said I'm kind of a newbie at this, and after googling all night I couldnt find anything of use, so I figured I'd ask the people in here who have dealt with this kind of thing before. I would appreciate some advice. Thanks.

Hi

When Windows reports a 750GB drive as 698GB that is perfectly normal.

The reason is that HDD manufacturers use 10^3 (1,000) to define 1 kilobyte - Windows use 2^10 (1,024).

ahh, okey doke. Thank you for clearing that up. Any idea about the second problem?

I have no idea why it does that.
But, if it's only for a split second and there are no other problems, I don't think you have to worry.
