considering the age of the system, that capacity is likely not supported

XP 32 is limited to 2TB on all drives except network drives.

You are wasting your money on a larger drive than the OS will support.

You might want to consider switching to Windows 7.  I have run Win 7 Pro on a dc7700 and it runs great.

With XP nearing its endlife early next year I think this would be a good move.

As the DC7700 has an Intel SATA controller on your Q965 chipset you should start troubleshooting by updating your RST drivers:

Anything over 2TB will need to be formatted GPT.

http://www.tomshardware.com/forum/268917-32-compatibility-formating-drives

I think you will be limited to 2TB for that system as it is a bit older.

ScottCha: got it right (at least the first part) It must be initialized as to gpt and not mbr.
easiest via the command line tool 'diskpart'  (the instructions below are for windows xp)
diskpart
list disk      ... this will show you a list of disk drives in your system with a number remember the number of the new drive
sel disk x             -- replace x with the number from above
clean                    -- this empties the information on the drive make sure you don't have anything you need on it
new gpt
create name="efi system partition" type=efisys Size=102
create name="microsoft reserved" type=msres Size=31
create name="basic data" type=msdata
 inspect   - this will show you the disk information
exit  == exits the dispart utility
http://support.microsoft.com/kb/297800

you may want to try just using everything before new gpt and try
"convert gpt'  
you can now
create partition primary   ((this will allocate the entire disk))
assign                         ((this will give it a drive letter)
exit

you will be promtped to format the disk (use ntfs)

Even formatted with GPT I'm pretty sure that Windows XP is unable to see anything beyond 2TB.

It can with an overlay utility

This is Seagate's which allows a 3TB drive to be seen by XP

Gary CaseRetiredCommented:
XP can't format a disk in GPT (except the x64 version).

What you're "seeing" is the space after 2TB [technically, you're seeing 3TB modulo 2TB]

There are a variety of things you could do ...

(a)  Return the drive and get a 2TB unit :-)

(b)  Use HDAT2 to set the max size of the drive to 2TB  (Use the Set Max feature)
http://www.hdat2.com/       You could later change this back to full size if you upgrade your OS.

(c)  Upgrade to Windows 7 :-)

I'd be inclined to do (b) until you're ready to do (c) or get a new system.

I thought i would be clever and install ubuntu and when i ran a lshw -class disk it dhowed the 3tb in terminal but when i browsed to the file system is was only showing 800gb?

maybe i need to format it? I will try installing win 7 maybe?
0
Gary CaseRetiredCommented:
As I noted above, one of the options that will let you use the full size of the drive is indeed to install Windows 7.    You will, however, have to install Windows 7 on a different disk, as you can't boot to a GPT disk unless you have a UEFI BIOS.

Then you can format the disk in GPT format from within Windows 7 and use the full capacity.

This tool will let you use the whole 3TB space of the drive without need to switch to Windows 7.

Note, you can use this drive as secondary drive only.

That or use an external enclosure and the USB2SATA will take care of it for you.. NOTE: not all will support 3TB read the box or be ready to return and try another enclosure until you find one that works.

hi guys,

i have installed win 7 but still only seeing 746gb

Windows 7 32 or 64bit?
Right click on My Computer - Manage - Disk Management - there see your drive. Right click on the drive (must be empty with no partitions on it) and select Convert to GPT.
Does it see yet 746GB?

Scott CSenior EngineerCommented:
That's becasue when it was formatted it wasn't GPT.  Once you convert it to GPT you will be good to go.

And Windows Disk Management shows it still as 7xxGB?
Can you take a screen shot of Windows Disk Management and post it here? Remember, it must be empty before conversion and then you should be able to use the whole 3TB space.

jonathanduane2010Author Commented:
ok how can i make sure its empty??

Scott CSenior EngineerCommented:
Go into DISKPART as you did before:

SELECT DISK x where x is your 3TB drive
CLEAN <return> (this will erase all data from the drive)
EXIT <return>

You should then be good to go.

Type the following command in the command prompt (administrator privileges), it would open the text file after the second command. Post the content of the text file here:

wmic diskdrive list full > %temp%\disk.txt

wmic volume list brief >> %temp%\disk.txt && %temp%\disk.txt

Thanks,

"... At this point I'd just return the drive and get a 2TB one. "  ==>  :-)   NO ... let's not give up yet.

First, the fact that it showed as a 3TB drive in Linux's terminal display indicates there's no issue with the hardware recognition of the drive.

The problem now is (most likely) that you (a) initialized it as an MBR disk ... which set it as a 746GB drive = the remainder after 2TB (i.e. 2TB modulo 3TB);  and then you converted that partition to GPT ... which doesn't change the characteristics of the disk, so it still shows as the wrong size.

There are two relatively simple ways to resolve this ... we'll try the easiest first:

Download Western Digital's Data Lifeguard for Windows [the download here is fine:  http://support.wdc.com/product/download.asp?groupid=608&sid=3&lang=en

Install it; run it; and select the 3TB disk -- be CERTAIN you've selected the correct disk !!
Then choose the Write Zeroes function ... and do it to the entire disk.

When that's done, close Data Lifeguard; then go to Disk Management, which will prompt you to initialize the disk -- do that [do NOT convert it to Dynamic if prompted];  and it will then be a 3TB GPT disk.    You can then simply create a partition and format it.

There's a small chance that may not work if you somehow ended up with a host protected area on the disk.    If that's the case, the above won't work -- if so, just post back and I'll outline how to resolve that.

Gary CaseRetiredCommented:
... Note:  Just in case it's not obvious, when you run Data Lifeguard and highlight the proper disk; you then click where it says "Click to run tests" ... and you can then select the "Write Zeroes" function.    You can try the quick write ... but if that doesn't do the trick, do it again with the full write (which will take several hours).

I have tried the full zeros it sees it as 3tb in the app, but when its finished and i initialise is a s a GPT disk i see 746gb again :(

Gary CaseRetiredCommented:
What does the BIOS show as the size of the disk?

Since Data Lifeguard shows the correct size, I don' think there's an HPA ... but I may be wrong on that, so try this:   Download the ISO for HDAT2 [ http://www.hdat2.com/ ] and burn a CD.

Boot to the CD, and "look" at the disk with HDAT2 -- see what the Device List shows for your drive.    If it shows "!SET MAX: HPA IS ACTIVE"  then the drive has a HPA that you need to remove with the "Set Max" function.

If that's not the case -- AND if the BIOS shows the truncated size -- AND you're using the current BIOS for your system [I assume you are since you said "i have updated the BIOS" in your description of the problem] -- THEN I'd agree that your system controller simply doesn't support 3TB drives.

If that's the case, you have two options:

(1)  Buy a controller card that supports drives larger than 2TB.    This one will work fine (you won't be using the RAID function, but it's an excellent controller):   http://www.newegg.com/Product/Product.aspx?Item=N82E16816115075    Simply plug it into your PCIe x1 slot and connect the drive to it.    Problem solved :-)    [And you can now support 2 drives of any size you choose to install -- 3TB, 4TB, 5TB, etc.]

(2)  Return the drive and buy a 2TB drive.

Scott CSenior EngineerCommented:
Don't be surprised if Ubuntu doesn't use the full disk size either.  You are trying to connect very large disk to an older machine that in all likelyhood will not see all 3tb.

I still stand by my suggestion to return the drive (if possible now) and get a 2tb one.
0
Gary CaseRetiredCommented:
I tend to agree, although an alternative is to use HDAT2 and the SetMax function to effectively turn the 3TB drive into a 2TB drive ... which could later be restored to full size when you eventually get a system that can use the full capacity.     Especially if you're past the "return window" for the drive.
