180GB HDD! Registry?

[Christopher Weber]

Hello,
I Installed a new 180GB (USB 2.0) on my WinXP machine. All seemed to be
normal; was recognized, partitioned it, formated, assigned drive letter, set
to active. Disk z:\ is Healthy, but doesn't show up! "z:\ Refers to a
location that is unavailable". I believe I read somewhere that a registry
key has to be set for disks >120GB. True? What is it?

Thank you, Chris.

Hi, Chris.

You set a USB drive to Active?

Are you trying to boot from this drive? Do you have any IDE or SCSI drives
in this computer?

This one?

To enable 48-bit LBA large-disk support in the registry:

1.. Start Registry Editor (Regedt32.exe).

2.. Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Atapi\Parameters\


3.. On the Edit menu, click Add Value, and then add the following registry
value:
Value name: EnableBigLba
Data type: REG_DWORD
Value data: 0x1


4.. Quit Registry Editor.
WARNING: By default 48-bit LBA ATAPI support on Windows XP Home Edition and
Professional is unavailable. Users must add the registry key mentioned
earlier to make this addressing available to access disk space beyond the
first 137GB. Data corruption can occur if previous versions of Windows that
do not support 48-bit LBA out of the box (for example, Windows 2000 or
earlier) are installed on a disk partition that was previously created by a
48-bit aware operating system such as Windows XP that is greater in size or
spans the current addressable limit of 137GB.
