Windows 2000 Drive limitation

Hi all,

I recently tried to install a 320 Gig SATA drive on a machine and install Windows 2000 on it. This drive had been in a machine running Windows XP and I was able to access the full capacity.

During the installation of Windows 2000, all I could access was 128 Gig and the rest of the capacity seemed all screwed up. Putting it back in the Win XP machine was not good. I actually had to start an installation on the drive to get the partitioning right again.

Any ideas? Is there a size limit in Win 2k that is not there in Win XP? This is a worry to me as I intend installing a RAID-5 setup (400 gig drives on a SATA plug in card) on a Windows 2000 Server machine in the future. Can imagine the frustration if I buy all the hardware and it won't work!!!
 
Or Install Service Pack 4 and ask for Microsoft how to enable Big LBA in the registry if it´s not automatically solved with Service Pack 4.
 
Thanks, that really helps explain things. Does not help getting the OS installed on the full capacity drive. Will just have to have a small partition to install and then format the rest once SP4 is installed.

I always seem to be trying to do these wierd things and land up with problems. But then that is the greatest way to learn.

Thanks again for the help.
 
Use a WinXP SP1 or SP2 cd to quick format in NTFS. It should recognize the full 320MB.

When the quick format reaches 100%, quickly turn off the computer. Then boot to the Win2K cd and install on the existing partition.
 
TBH I always have a small partition just for the OS anyway. Then use the rest of the drive for data etc.

Also makes imaging easier. If you need to reinstall the OS, then you can just format/reimage the OS drive rather than wiping out all of your data too.

I'd suggest a 20Gb OS drive, then once Win2K with SP4 is installed you can use the enable big LBA tweak to see the rest of the drive.
 
Sounds like you are installing with a W2K CD that DOES NOT have AT LEAST SP3 slipstreamed into it. Bad idea.

First thing that you need to do, is to create a "slipstreamed" W2K disc with SP4 added into it. Then use that CD to install, and it should (in theory) allow you to recognize greater-than-128GiB HDs.
