hard drive problem

Hi all, i recently built my first ever system and amazingly i got everything working 1st try (yay me!) but i have one slight problem, my second hard disk is 160gb and is working fine apart from windows claims it is only 115gb? On start up it says 160gb and bios says the same. I have an 80gb one installed and its working fine, both drives are Seagate Barracuda 7200.7 SATA 8MB and my motherboard is an Asus A8N-SLI deluxe (i'm assuming i have them connected right into sata1 & 2?).

Any help appreciated

 

What OS are you using?

Also when you installed the 160g did you set up any partitions?

Is this drive brand new, or used?

If its used, it may have a previous partition set up that wasn't removed.

 

running XP home, fully updated. i didnt create any partition and the drive is brand new. Could i have installed it incorrectly? I'm new at this remember so feel free to give me a step by step guide of what i should have done

 

You say that your running XP but does it have any of the service packs installed.

There are two inter-related areas with regard to drives that exceed 137Gb capacity. One is the need for 48bit LBA within windows to have partitions greater than this size and the other is to have a BIOS that is itself able to address a drive of that size.

If your bios is correctly detecting the size at boot then the next issue to address is XP. In it's basic form xp cannot recognise HDD >137Gb it does not have 48bit LBA. This is only present in SP1. In addition there could well be a further requirement to update the Atapi.sys file version by applying the hotfix below.

Apparently none of this is needed if you have SP2 installed. Do you feel brave enough to do this.......

 

thnx risk, this sounds like the problem. The drive was hooked up before i updated to SP2 so i assume it wont automatically display the correct capacity?
