Why 28.56 Gb on my 30.7 Gb Ibm 75 gxp?

[pebe]

I got to partitions, one at 4.66 and the other as 23.9 and there was 7 mb or so wasted says PM 4. Why is it like that and how to fix it. That's more than 2 gig and I want it back
Thanx

Don't worry...that's normal. On most hard disks there is some space, usully less than 10% of the HD size, that cannot be used. On my old IBM Deskstar 10.1GB drive I could only use about 9.3GB.

Hard drive manufacturers advertise in bytes as opposed to megabytes or gigabytes. You will find that you have 30.7 billion bytes on the hard drive, but since 1048576 make up one megabyte, I think you will find that 30.7 billion bytes is actually effectively 28.56GB in reality.

My 20.5GB Quantum LM clocks up only about 19.3GB as well.

Remember that there is also partition and file system overhead. FAT32 and NTFS require quite an amount of space for their file allocation tables.

I'll write this again....

Advertisers consider 1 GB to be 1 billion bytes.
Computer OS'es, any programmer or anyone who's good with computers knows that 1 GB is actually 2^30, which comes out to over a billion (1,073,741,824) bytes. When your OS tells you that you have 28.56 GB, it's using the 2^30 calculation, which comes out to 30,666,066,493 bytes, or 30.7GB if you round that off and use the 1GB = 1 billion bytes system.

Must I say it every time?

HD makers say:
1 KB = 1,000 bytes
1 MB = 1,000 KB = 1,000,000 bytes
1 GB = 1,000 MB = 1,000,000,000 bytes
30GB = 30,000,000,000 bytes

Microsoft says:
1 KB = 1,024 bytes
1 MB = 1,024 KB = 1,048,576 bytes
1 GB = 1,024 MB = 1,073,741,824 bytes
27.93 GB = 30,000,000,000 bytes

Ok, I got it
thanx all

<< Microsoft says:

This is no Microsoft, this is true definition of KB, MB, GB

This discussion is going for years, HD makers want you buy &quot;bigged&quot; HD, than it really is

 

[Techwhore]

it's definitely not microsoft. If that were the case, there'd be more competition in the OS market to make more use of your HD, not that that doesn't already go on. Besides, even RAM is measured on these standards, it's not OS or Hard drive dependant, it's simply just the way it is. It's amazing memory manufacture's don't advertise larger modules like 128's as 131's... guess it's just a nice round number people will accept

Like I said, it's a computer standard based on the base-2 system. It's not microsoft's word, it's the words of all computer makers/programmers from the past 20 or so years.
