New PC

  The Dazza 12:17 20 Jun 2006

I have just bought a new pc and was told it has a 160gb hard disk. When I look on properties for the drive it says capacity 137,427,943,424 bytes 127GB. I know the full capacity doesn't normally show but this cant be right - can it?

Could well be that the system has a hidden partition which is being used to store your operating system for recovery purposes. However, I double this would take more than a couple of GB and you seem to be adrift by 30 Gb. But it could be that the balance simply hasn't been formatted as a virtual drive.

Check what you system says when you first boot - should give the HDD model, and see what that indicates. Also, if you have something like Partition Magic, you can see what else is hidden on the drive.

Whatever you do, don't open the box, as this could invalidate any warranty. If software cannot answer, I would challenge the supplier for an explanation.

When I got the machine it wasn't formatted so I just booted up with the xp disk. How will I be able to tell the correct disk size as there is nothing obvious on boot up and computer management is saying 127.99GB. Thanks

You say "but it could be that the balance simply hasn't been formatted as a virtual drive" - how do I check this?? Thanks

Go to control panel then admin tools then disc management and see what it says you might have a non formatted partion.

Hard drive capacities are a pain in the arse. When they're made, all the 0's and 1's (bytes) on the drive that store the data add up to the nearest 1000, and a GB is 1024 MB and a MB is 1024 KB and so on - which means it has less space than what is quoted on on the label, because the label on the drive that tells you it's capacity - for some unknown reason - measures it to the nearest 1024 to try and give a round number in gigabytes. So a cheap 80 GB drive will contain 80,000,000,000 bytes, and this is just labelled as 80 GB, when it's true value is around 74.4 GB when you do the maths. And the larger your drive the more you lose and if the computer was fitted with a cheaper drive you lose even more because cheap drives don't try to compensate for the capacity lost. Anyway labelling drives as 160 GB when they're clearly not is wrong and I'm sure one day they will be labelled with their true values. Also the NTFS file system that Windows uses does take up a bit extra space but not a great deal.

FDISK from the C:\ prompt or using any Partition Manager

Yeah, I thought of this myself and came up with what I thought myself was rather confusing, here goes:
Current fixed disk drive:1
Partition 1, Status A, Type NTFS, Mbytes 65526, Usage 100%, Total disk space is 21553 Mbytes

How do you get 160GB from that then??

I know my pc needs a bios update before it will show the full 160 but you should not need to do this with a new pc.
