Probably need a BIOS update to detect larger drives. Check with your mainboard's manufacturer. Flashing the BIOS is not something to be done lightly however, read up a bit first maybe.

2 options,

If you have windows xp on service pack one, upgrade to service pack two

If you have service pack two, enable 48bit lba in the bios, This is done by pressing delete ( usually ) when you turn on the pc.

Its something to do with the 48bit LBA thing. Look here for info: http://www.48bitlba.com

this could also be to do with your file system. What are you using? FAT32 can mess up the true storage space of large disks. NTFS wouldn't so if you're running XP and your disk is FAT32, go to cmd and run:

"CONVERT C: /FS:NTFS"
This will also work for external drives, and won't erase the data on your disk

EDIT: to remove typos :P

Its definitely the 48bit LBA problem and pay no attention to that last post if you want to keep your data .

You need to either upgrade your service pack or switch on large drive support in your bios.

Actually, convert does keep your data, it doesn't format your drive, just converts it. And yes, FAT32 is not designed for drives greater than 40gb so my post was a perfectly valid one.

Prolly Bios.

Was for me anyway.

Could also be a jumper setting on the HDD; a long shot I know, but had the same problem with a 200GB Samsung EIDE HD which was only registering 32GB.

Also please dont expect to get the full 180GB out of a HDD, thats the size of it unpartitioned and without a file system.

My NTFS file system took about 20GB on my 200GB HDD,

But other reasons are perfectly valid, upgrade BIOS, get SP2 if you can, and check out the LBA 48-bit problem too (wouldn't have thought of that one)

look just turn on 48bit lba in the bios, like i said originally

I had exactly the same problem with a new hard disk in an older pc, it too would only see 127gb. I used partitioning software on Hirens Boot CD to partition the disc making two partitions each below 127gb in size and hey presto it saw both. Google Hirens Boot Cd, download it and you'll never look back....

FOR THE LAST ****ING TIME, ENABLE 48BIT LBA IN YOUR BIOS, YES YOU CNA PARTITION, BUT WHY BOTHER?

What is 48-bit LBA?
48-bit Logical Block Addressing (LBA) is a technology which extends the capacity of IDE ATA/ATAPI devices beyond a previous limit of 137.4 GB. This limit applies to IDE ATA/ATAPI devices only and not to SCSI interface devices. The original design specification for the ATA interface only provided 28-bits with which to address the devices. This meant that a hard disk could only have a maximum of 268,435,456 sectors of 512 bytes of data thus limiting the ATA interface to a maximum of 137.4 gigabytes. With 48-bit addressing the limit is 144 petabytes (144,000,000 gigabytes).

Anyone who puts larger HD's into Xbox's should be very familiar with this issue
As Anti said upgrade to SP2 or enable 48 Bit LBA in the BIOS.

Post of the year imo.
