Discussion Overview

The discussion revolves around an issue related to hard disk drive (HDD) capacity and potential hidden or unreachable sections of the drive. Participants explore the implications of disk formatting, operating system behavior, and the possibility of bad sectors or manufacturer partitions. The conversation includes technical explanations and personal experiences with different operating systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant reports an inability to write to 2GB of their HDD, noting that the space appears empty.
  • Another participant suggests that HDD capacities are measured in base 10, contrasting it with RAM, which is measured in base 2.
  • There is a discussion about the potential for bad sectors or issues with low-level formatting affecting the HDD.
  • Some participants mention the concept of unreachable sections on the drive, possibly due to BIOS or software limitations.
  • One participant expresses frustration with the Vista operating system, suggesting it may store data outside the defined disk file system structure.
  • Another participant points out that certain directories in Vista are not directly accessible, indicating a possible alias link rather than a traditional file structure.

Areas of Agreement / Disagreement

Participants express various viewpoints regarding the behavior of HDDs and the impact of operating systems, particularly Vista. There is no consensus on the cause of the reported issue or the nature of the unreachable space on the drive.

Contextual Notes

Some participants mention the limitations of their knowledge regarding HDD formatting and operating system behavior, indicating that further research may be necessary to fully understand the issues discussed.

when I was running a standard check on my HDD I found when I ran my disk filler (to completely delete my files PM me if you don't understand) i found 2Gb would not write i checked the binary point only to find it was empty.. absolutely nothing (just before anyone says my OS is on a separate part of the drive :smile: )
Does anyone know what this is?
 
Computer science news on Phys.org
I'm not quite certain what's going on with your hdd, but do remember that hard drive capacities are base 10, not base 2 like most other capacities on a computer.

What software are you using to erase your disk and what sort of file system are (were, hehe) you using?
All of you manufacturer stated hdd capacity should be available to you.

While a GB of ram is 2^30 bytes, a GB of hdd capacity is 10^9 bytes.

It's possible you have bad sectors or have something strange about your low level formatting if you've messed with it(defining how many tracks, sectors per track ... etc.)

Bits, not bytes :wink:
 
Capital B stands for bytes, if I'm not mistaken.
Lowercase b stands for bits.
 
say my drive is split into 10 sections:
section 1 approx 20 GB - OS Systems
section 2 approx 20 GB - Boot Files etc...
section 3 approx 20 GB - Other Files
section 4 approx 20 GB - Other Files
section 5 approx 20 GB - Other Files
section 6 approx 20 GB - Other Files
section 7 approx 20 GB - Unreachable
section 8 approx 20 GB - Other Files
section 9 approx 20 GB - Other Files
section 10 approx 20 GB - Other Files

My Copy of windows is legit and most (if not all) software is legal.
*these days your always illegal in someone's eyes!*
 
Sorry, my mistake, no idea what I was thinking about :blushing:
 
Unreachable implies that there is a BIOS, O/S or Software limitation.
Might depend on how old your stuff is.

There at one time was a manufacture partition that remapped bad sectors with "spare" good ones. It required special software to update. Don't know if this method still exists or if that is what you are finding.
 
I believe mapping between sectors numbers and physical sectors have lost any meaning several years ago. HDD is a black box where you put number (of sector) and you are given numbers (data from that sector) back. In general you have no control over what is happening inside.
 
ahh but my computer is new... and is running Vista
I HATE VISTA and am planning to return to XP soon
(i BOUGHT the computer with Vista, i didn't upgrade my old one)

No argument on vista (it came with my laptop).
Ok, as an internet appliance, but as an OS...

No idea what you are using to scan your disk.
While I haven't researched it, I do have some indication that Vista keeps some data outside of the defined disk file system structure.
This idea may or may not be correct.

Here's a test for anyone who is interested...

Open MY COMPUTER *(Only on Vista Pc's)

on the addresses bar type 'C:\documents and settings\'
I know there is no such file even hidden yet an error message pops up and says:
'Error:You are not allowed access to this file'
Is This a VISTA blackspot?
I Knew it sucked but come on...

You can try opening it on MS-DOS
error: Drive not accessible

What is up?
i don't know.

(Someone should email bill gates...)

Ok, that I kinda know about (not a lot).
There really isn't a file -- it's some sort of alias link.
To get there directly from mycomputer you need
c:\users\xxxx\docments where xxxx is your user id.

All of these funky links have the funny arrow icon on them.

EDIT: or you can just click the xxxx directory and get the same thing.
Or it really is organized the old way but vista forces you to use the overlayed new links
