How to get XP Pro to recognize a WD 200GB HDD??

[Guest]

Hello,

I am trying to figure out how to get XP Pro to see my WD 200GB hard drive as
a 200 and not a 137GB. Any clues? I know this story well but have never had
to deal with it until now. Will the SP2 update rectify this by any chance?
Thus far I have only partitioned it to C: at 12GB. The rest is untouched. I
will wait to see what is up from some responses here first before proceeding
any further. Cheers to all the for the help and Happy Holidaze!

Does your hardware (BIOS) recognize the full size of the hard drive?
What does Disk Manager see?
Do you not have at least SP1?

If you have at least SP1 installed and your hardware recognizes the hard
drive, then Windows XP will recognize the hard drive. You *will not* get
200GB out of it... But that has more to do with marketing than what OS you
use.

Why is the full capacity of EIDE drives larger than 137GB (128GB binary) not
recognized in Windows 2000/XP?

Chout:
As Shenan Stanley implies, the first requirement is that your motherboard's
BIOS supports large-disk capability, i.e., hard disks larger than 137 GB. So
everything that follows assumes that you have this BIOS support.

The second requirement is that SP1 or SP2 has been installed to your OS.
I take it that when you installed your 200 GB HD you did not have SP1 or SP2
installed. Under that scenario only 137 GB of your HD would be recognized by
the OS. When you subsequently install SP2 the full capacity of the drive
will be recognized, i.e., about 186 GB (this is what Shenan is alluding to
when he says you will not see the entire 200 GB -- it's the difference
between the manufacturer's advertised disk capacity and the different
capacity computation employed by the OS).

Now you say you've created a 12 GB partition. I'm assuming then that you did
not format the remaining "unallocated space". When you subsequently install
SP2, the remaining capacity of the disk will be recognized and you will be
able to create one or more partitions and format those partition(s).

Re HillBillyBuddhist's referral to the WD site that purports to explain the
reason(s) why the original release of XP did not support large-capacity
disks - I've never come across any reasonable explanation from Microsoft or
anyone else as to why this limitation was imposed. Certainly the technology
was present at the time the original XP OS was released in mid-2002 to
easily incorporate a provision within the OS allowing the full recognition
of disks having a capacity > 137 GB. I can only assume Microsoft had good
and sufficient reasons for doing so but it's a puzzle to me.

not* get 200GB out of it... But that has more to do with marketing
than what OS you use.

actually it's 186.31 GB. comes from the different ways to count KB, MB,
GB etc. While Harddisk manufacturers count 1.000 Byte as one KB, 1000KB
as one MB, etc. Everything else counts 1.024 Bytes. And that adds up
when it comes to Gigabytes.....

Which is what I said - marketing..
(Marketing - real numbers vs technical real numbers.. heh)

Thus far I have only partitioned it to C: at 12GB.

To use a disk bigger than 137 GB (decimal billion) you need to have '48
bit LBA' to be able to hold the sector numbers of sectors beyond that
point. That needs a BIOS that recognises 48 bit LBA and reports the
full size, and then XP with SP1 at least. And I don't think the
partitioning/formatting in the initial setup handles it; but that
initial partition would need to be nothing like that big. Once the
system is installed in a modest size partition you can go in XP to
Control Panel - Admin Tools - Computer Management, select Disk
Management and look lower right for the graphic of the drive. R-click
in Unallocated space and Create Partition. BTW a 200 GB decimal
becomes about 185 of the 'binary' GB used in measuring partitions

(I'd go a bit bigger than 12GB for C:, but that's not too bad if you
make sure things like My Documents are elsewhere)
