My computer setup before reinstalling a fresh copy of WIndows XP is
P4 2.8 Ghz on a Intel PERL Motherboard, 1GB RAM, 128MB Video,
Partitioned PATA 80GB Seagate (C: 40GB, D: 40GB) hard disk, SATA
250GB hard disk (E:), SATA 320GB hard disk (F:). Installed is
Windows XP SP2 with the latest updates by Microsoft. This setup is
already a year old so I've decided to reinstall a fresh copy of
Windows XP. After successfully installing a new Windows XP SP2, I
couldn't access my 320GB hard disk and everytime I boot up my
WIndows XP scandisk always run. I always cancel the scandisk
because I'm afraid that I might loose my valuable data if scandisk
corrects the problems found by scandisk.
Windows XP tells me that my 320GB hard disk is not formatted. I
opened Computer Management to see the list of drives and found out
that my 320GB hard disk is only detected as 130GB hard disk but in
the BIOS it says 320GB hard disk. After doing some research on the
net, I found out that Windows XP doesn't automatically support
large hard drives greater than 130GB (I think). I edited the
registry and added DWORD EnableLargeLba = 1 then rebooted my PC.
After the reboot, Windows XP still reports that my 250GB hard disk
has problems. Opened Computer Management again and checked my hard
drives. Computer Management now reports that my 320GB hard disk has
130GB (healthy) and 170GB (unallocated).
I also lost some data and corrupted files on my 250GB hard disk.
I think the cause of this was Windows XP automatically reconfigured
the partitions on my hard drive since it doesn't support large hard
disks greater than 130GB.
Is it still possible to recover all my data on my 320gb hard disk
and 250gb hard disk drives? What should I do? I am sure that my
hard drives are working in good condition because I just bought
them a few months ago.

Your results from your research was incorrect or at least incomplete.
As long as you installed Windows XP SP1 or SP2 initially (not updated it
to
SP2) - the support was there from the beginning.
You may be having trouble with the drivers for the controller?
Update those from the controller card or motherboard manufacturer?
(If built into the motherboard - the chipset drivers should cover that.)
No one should have suspected a hard disk issue from the information you
gave...
When you installed Windows XP - was it from a CD integrated with SP1 or
SP2?

Thanks for correcting me, I reviewed the article again. But why is it that
my hard disks is not recognized correctly by Windows XP? What I did was, I
installed a Windows XP (not SP1 and SP2) and reinstalled Windows XP SP2.
IJVelas:
It would appear that when you originally installed XP (sans SP1 and/or SP2)
the 137 GB disk capacity limitation was invoked, i.e., both your 250 & 320
GB HDDs would have been affected. So the system would not recognize disk
space > 137 GB (approx.) under those circumstances. Presumably while you
were using those two HDDs during the time SP1 and/or SP2 was *not* installed
you could not have utilized any disk space > 137 GB (approx) so I don't
understand how you could create any data on that space - data that you infer
has been lost. Are you certain about this? Are you perhaps referring to data
on the 137 GB partition? And (in this connection) you mention only the 320
GB HDD as being affected by lost data. Not the 250 GB one although you do
indicate there is a problem with lost files & corrupted data re that HDD but
it's not clear whether you're referring to the problem involving disk
capacity recognition here.
Now when you fresh installed XP w/SP2 to your 80 GB HDD (it *was* to that
HDD, right?), the system would now recognize the full capacity of your 250
GB & 320 GB HDDs, however the additional disk space > 137 GB (approx) would
have been designated as "unallocated" - disk space that you could
partition/format on both the 250 GB & 320 GB HDDs. Again, I'm assuming the
250 GB HDD was similarly affected as the 320 GB, presuming that the 250 GB
HDD had been installed when you originally installed the XP OS without SP1
or SP2.
The problems you mention re scannow and that "Windows XP tells me that my
320GB hard disk is not formatted" indicate that something is amiss with your
system - probably having something to do with your fresh install of XP or
something else. Assuming this is practical I wonder if at this point it
would be advisable to undertake a new fresh install of XP - making sure that
*all* other HDDs and storage devices are disconnected from the system during
this fresh install (presumably to your 80 GB HDD - I take it for one reason
or another you prefer the OS to reside on that HDD rather than on one of
your large-capacity HDDs. I don't know why - it wouldn't ordinarily be my
choice but I take it you have your reasons). I'm assuming you would have no
difficulty re:installing your programs & applications following the fresh
install.
Or in lieu of a new fresh install of the OS you could perform a Repair
install on that boot drive. Again, ensure that all HDDs & storage devices
are disconnected from the system during that operation.
I'm not sure whether you'll be able to restore any lost data from your two
SATA HDDs after this. There may be other problems affecting this situation.
