<0> hm....
<0> i had a lot of trouble getting my machine to see all 200G of space
<1> What harddrive is this?
<0> hey you see the other drive?
<0> maxtor 200G ata
<0> C:
<0> hey you see the other drive i have that's listed as 149.05G?
<1> Yes
<0> that drive's sposed to be 160G
<1> New Volume F:
<0> what happened to 10G?
<1> 149.05 GB
<0> something about how bytes and bites are counted?
<1> Uhm.
<1> Yes.
<1> You see.
<1> A 200 GB harddrive isn't really technically 200'000'000 MegaBytes
<0> how come
<0> i heard some explainations before but i forgot
<1> A 200 GB Harddrive is 200'000'000'000 bytes big.
<0> ah
<0> but not all is free
<0> cause it's too far to the edge or something?
<0> heh
<1> No.
<1> My Harddrive is 250 GB
<1> 250'000'000'000 Bytes
<1> 250'000'000'000 Bytes = ~230'000'000 Megabytes
<0> oh
<0> how come?
<0> oh wait
<0> is that in hex?
<1> Read here
<1> http://www.winbookcorp.com/_technote/WBTA14000543.htm
<0> 250'000'000'000 Bytes != 250,000,000,000
<0> ok
<0> ah
<1> 1 meg = 1'048'576 bytes
<0> ok
<0> how come?
<1> And if you take your 200'000'000 Megs
<0> incidentally my old hd died
<1> Oh sorry
<1> I ment
<1> You take how big your harddrive is in BYTES
<1> Which is 200'000'000'000
<1> And divide that by a megabyte in bytes (which is 1'048'576)
<0> ok
<1> 200'000'000'000 / 1'048'576 = 190,77486328125
<1> = 190,77486328125 gig
<0> ah
<1> a *real* 200 Gig harddrive is not 200'000'000'000 bytes
<1> A *real* 200 gig harddrive needs to be 1'048'576 x 200'000
<1> Which is way more than 200'000'000'000 bytes
<0> ok
<1> That's how Windows counts the megabytes.
<0> how come windows count it like that?
<1> But the hardware manufacturers counts the harddrives in BYTES and not gigabytes.
<2> anyone have a proggy to decrypt p***words?
<2> from ****** to letters
<1> But it would be utterly nuts to market harddrives as "Maxtor 200'000'000'000 bytes 7200 rpm 8ms ATA"
<1> Woudn't you say?
<1> MsPunjabe: Go to your "My Computer"
<1> MsPunjabe: Select your harddrive
<1> MsPunjabe: Select Properties
<1> MsPunjabe: And tell me how many BYTES are displayed there
<1> And it will all make sense =)
<0> 137,436,168,192 bytes, 127GB
<0> cool
<1> You harddrive is 140 gigs, right?
<0> nah
<0> 200
<1> Yes, but a 140 gig partition, right?
<0> oh yeah
<1> 137,436,168,192 bytes <--- There is your 140 Gigs.
<0> cool
<0> ok
<1> Except 7 megs that are there for the bootsector I think.
<0> that's good
<0> oh yeah
<1> =)
<0> :D
<1> It makes way much more sense now.
<0> yeah
<1> 137,436,168,192 = 127 GB
<0> but why is GB counted differently from Bytes?
<1> Because 1048576 bytes = 1 MB
<3> hd makers cheat
<0> oh
<3> they use 1000meg = 1 gig
<3> in binary it's 1024
<1> 1048576 bytes x 1000 = 1 GB
<0> hm...
<1> And so on.
<1> They don't cheat.
<4> That is cheating kinda
<4> When you call 1,000,000 a mb
<1> Kind of yes. But only almost =P
<4> when it clearly isn't
<1> Yah.
<4> It'd be okay IF 1,000,000 was the standard
<1> But it's not ;D
<1> MsPunjabe: So in order to caluclate how much REAL space you will get out of a harddrive.
<1> MsPunjabe: Just divide the ammount of bytes that's in a meg with the size of the harddrive in Gigs.
<1> So for instance - like me if you have a 250 GB harddrive.
<1> Just do the math: 200'000'000'000 divided by 1048576 bytes
<0> oh
<1> Oh sorry
<0> cool 250
<1> I ment 250 gigs
<0> ok
<1> Which is 250'000'000'000
<0> what's happening when you format a drive?
<4> 99% it's checking disk integrity and stuff
<4> 1% it wipes the data
<0> where does it say if a drive is formatted or not?
<4> for what?
<0> into fat32 or ntfs?
<0> like when you look at a drive
<0> physically
<0> how do you know its ntfs
<0> or fat
<4> physically?
<4> you don't
<0> well
<0> is there some spot where your machine writes down
<0> 'fat32'
<1> 250'000'000'000 divided by 1048576 = Somewhat 238 gigs
<4> the filesystem is something that's completely contained on the platters themselves
<1> Which is the total ammount of GB you will be able to free.
<4> MsPunjabe, yes on the drive itself....
<0> what are platters?
<0> Akuma cool
<4> platters are where your data is stored
<1> So.
<0> so after you format a drive
<4> the disc lookin things inside
<0> your drive writes down 'ntfs'
<0> my hd died
<0> old one
<0> i took out the discs
<0> should i have kept them?
<1> [Size of harddrive in bytes] / [size of one megabyte in bytes] = REal size in GB
<0> and put in another drive to see if it reads?
<4> ntfs is a filesystem, and a filesystem is basically how the OS will store its data
<0> akuma cool
<4> it's a structure
<4> so to speak
<5> ha, for a second there I read that as "ntfs is a lifestyle"
<0> it's a software structure only?
