As long as your BIOS and Chipset supports 48Bit LBA.

Most computers made after 2004 should be OK.
2003 to 2004 was a transition period so a PC made in this
time frame may or may not support 48Bit LBA or
will at least need a BIOS update if available from the
PC manufacturer.

Please, I posted a reply already. In case you wanna have a look
at it.

You need SP1 or SP2 for Windows XP to support drives larger than 137GB.

48Bit LBA Info:
http://www.48bitlba.com/winxp.htm

Also see MS article:
How to enable 48-bit Logical Block Addressing support for ATAPI disk drives in Windows XP
http://support.microsoft.com/default.aspx?scid=kb;en-us;303013&Product=winxp

You can verify if your PC does or does not support large drives (48Bit LBA)
by using a utility named HD Tune: http://www.hdtune.com/
Download, install and then run HD Tune, then click on the 'Info' tab.
Is there a check mark in the 48Bit-address box? If it is not checked then
your PC most likely does not support 48Bit LBA.

Also there is Belarc Advisor: http://www.belarc.com/free_download.html
Note: Belarc identifies the IDE/ATA controller (part number) on your
motherboard, you then need to Google this part number to find if the
controller/chipset identified by Belarc supports 48Bit LBA.

Hello ng,

I read about the Windows larger hard drive barrier effecting drives larger than 137 GB
and would like to know what limited support for such large drive does mean and how
to, in some way, enable full support for such large drives.

Sincerely,
Steve




Thanks for your replies.

I found the Atapi.sys file on my computer. It's on several locations and in
system32/drivers.

The version Nr. was 5.1.2600.5512. This was a later version than the noted
one, wasn't it. This should be ok as it was. Right?

Steve
