Pomoć Hitachi 500GB HDD

[Razarac]

Kupio sam Hitachi HDD 500GB al mi ga Windows Vista prepoznaje kao HDD od 465,76GB šta mi je preveliki "gubitak".
Probao sam sa Norton Partition Magic --- NE podržava Vistu
Acronis Disk Menager prepoznaje 465,80GB
Paragon Hard Disk Menager 465,70GB
A u BIOSU normalno pokazuje 500GB i HD Tune pokazuje 500gb.
Skinuo sam i Hitachi Drive Fitnes i on pokazuje 500,11GB.

Zna li netko sa kojim bi programom formatirao HDD a da nemam "gubitak" od 30GB - 35GB ?

Svaki prijedlog je dobrodošao

to ti je normalan gubitak ... odnosno ovih 500 postoje samo na papiru proizvodjaca ...

[Lewis]

Da, razlika je u racunanju . Proizvodjaci racunaju/zaokruzuju na 1000 a ne 1024 i tako se "pogubi" putem toliko GB koliko smo do prije par godina imali diskove (30-40GB) .

BTW nema veze sa Vistom isto je i na XPu tako da se ne brines .

Pa malo mi je preveliki gubitak od 35-40GB to je čitavi jedan "stari" hard (koji i dan danas koristim) al muči me što ga bios ,HD tune i Hitachi Fitness prepoznaju kao disk od 500GB.

prepoznaju ga tako jer mu je tako ime i to je to , i za moj pise 160gb gdje god pogledam ali kapacitet mu je 151gb ...

Pa on je 500GB ali nije 500Gb - ista stvar sa DVD-R medijim - 4,7 GB = 4,38Gb .

Bit vs byte


The metric system

In some cases when used to describe data transfer rates bits/bytes are calculated as in the metric system as follows:

• 1 MB = 1,000,000 bits/bytes
• 1 kb = 1,000 bits/bytes
• 1 bit/byte

• 1 byte = 8 bits
• 1 kilobyte (K / Kb) = 2^10 bytes = 1,024 bytes
• 1 megabyte (M / MB) = 2^20 bytes = 1,048,576 bytes
• 1 gigabyte (G / GB) = 2^30 bytes = 1,073,741,824 bytes
• 1 terabyte (T / TB) = 2^40 bytes = 1,099,511,627,776 bytes
• 1 petabyte (P / PB) = 2^50 bytes = 1,125,899,906,842,624 bytes
• 1 exabyte (E / EB) = 2^60 bytes = 1,152,921,504,606,846,976 bytes

Gle to je to, to je normalno i nemozes nista. Mozes se zaliti upravi vodovoda jedino.

Tal ti je i kod mene i kod svih ostalih. Vidi:

Da je velik gubitak jest ali sta se moze , nismo se pobunili (kupci) kad je bilo vrijeme (kad su diskovi poceli rasti i kad se sve vise vidio gubitak na razlici racunanja) a sad je kasno .

EDIT: Evo ovaj text pojasnjava problem - zabunu


As of 2007, most consumer hard drives are defined by their gigabyte-range capacities. The true capacity is usually some number above or below the class designation. Although most manufacturers of hard disks and Flash disks define 1 gigabyte as 1,000,000,000 bytes, the computer operating systems used by most users usually calculate a gigabyte by dividing the bytes (whether it is disk capacity, file size, or system RAM) by 1,073,741,824. This distinction is a cause of confusion, as a hard disk with a manufacturer rated capacity of 400 gigabytes may have its capacity reported by the operating system as only 372 GB, depending on the type of report.
The difference between units based on SI and binary prefixes increases exponentially — in other words, an SI kilobyte is nearly 98% as much as a kibibyte, but a megabyte is under 96% as much as a mebibyte, and a gigabyte is just over 93% as much as a gibibyte. This means that a 500 GB hard disk drive would appear as "465 GB". As storage sizes get larger and higher units are used, this difference will become more pronounced.
Note that computer memory is addressed in base 2, due to its design, so memory size is always a power of two (or some closely related quantity, for instance 384 MiB = 3×227 bytes). It is thus convenient to work in binary units for RAM at the hardware level (for example, in using DIMM memory units). RAM memory size as seen by application software has no consistent bias towards power of two units, as the operating system will allocate memory in other granularities. Other computer measurements, like storage hardware size, data transfer rates, clock speeds, operations per second, etc., do not have an inherent base, and are usually presented in decimal units.
An example, take a hard drive that can store exactly 250 × 109 or 250 billion bytes after formatting. Generally, operating systems calculate disk and file sizes using binary numbers, so this 250 GB drive would be reported as "232.83 GB". The result is that there is a significant discrepancy between what the consumer believes they have purchased and what their operating system says they have.
Some consumers feel short-changed when they discover the difference, and claim that manufacturers of drives and data transfer devices are using the decimal measurements in an intentionally misleading way to inflate their numbers. Several legal disputes have been waged over the confusion. See Binary prefix — Legal disputes.
To further complicate matters, flash memory chips are organized in multiples of 2, but retail flash memory products have available capacities specified by multiples of 10. Removable flash storage products contain file systems that make the devices behave like hard disks instead of RAM, yet it is called 'memory'. In operating systems like Windows Vista, flash memory can indeed be treated like RAM.
The basis of the problem is that the official definition of the SI units is not well known,[citation needed] and some legal settlements include directions for manufacturers to use clearer info, e.g. by stating a hard disk's size in both GB and GiB. However, JEDEC memory standards still uses the IEEE 100 nomenclatures.

AH pa onda nema pomoći a cijeli dan se mučim več sam lud.

THX svima na pomoći

Jos samo jedan sitan dodatak.
BIOS ocitava velicinu diska na taj nacin sto mu hard disk kaze kolko ima, u tvom slucaju 500gb.

Windows i vecina programa izracuna velicinu, i dobije tih 465gb.. Tako je to, zanima me samo koliko zapravo ima onaj od terabajt!
