WinXP hard drive limit of 137GB

  rithym 08:14 31 Oct 2003

Hi to all
I have just done a clean install of winxp home on a brand new maxtor 250GB hd (master, no slave). My pc is a p4 and has the latest bios and does report the hd as 250GB in cmos setup but after partition/ format & installing winxp home the drive is reported in xp as being only 137GB. I understand this has something to do with xp limitation of hd size.
I have connected to windows update and installed SP1 which i read overcomes this problem but after a restart xp still reports hd as 137GB.
Any advice to get the full drive capacity much appreciated. Thanks in advance

This is taken from this article, rithym. Hope it helps a little. click here

"XP Service Pack 1 (SP1) adds support for 48-bit Logical Block Addressing (LBA) for ATAPI drives, which lets the OS access hard disks larger than 137GB (the current limit). For this change to work, you must have

- a 48-bit LBA-compatible BIOS
- a hard disk with a capacity greater than 137GB
- XP SP1

To enable 48-bit support, perform the following steps:

1. Start a registry editor (e.g., regedit.exe).
2. Navigate to the

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters registry subkey.

3. From the Edit menu, select New, DWORD Value.
4. Enter the name EnableBigLba, then press Enter.
5. Double-click the new value, set it to 1, then click OK.
6. Reboot the machine for the changes to take effect."
