3TB Hard drive only shows 746Gb (Server 2003)

I was trying to set up the 3TB drive as a mirror for a 2TB drive. It was just fine (showed all 3TB) and when I tried to create a new partition, mirror wasn't an available option.
I didn't understand why, so I tried converting back to basic disk and to MBR (in desperation) and then the drive started only showing as 746.39GB.
Does anyone know how I might get it to show all 3TB again? I tried uninstalling the disk from device manager and reinitializing. I tried "CLEAN" from the diskpart tool, but nothing. It always comes back as 746Gb.
If I can't get it to mirror, I don't guess it matter, so if anyone has any input on that too, it would be appreciated.

Hi,
1. Convert it to GPT instead of MBR and see the result.
2. If issue still exists, it could be a hardware related issue. You could try to contact hard disk manufacturer for a firmware update which should able to resolve the issue.
A similar thread which point to Intel chipset update.

Cannnot use 3TB hard drive to install Windows Server 2008 R2

I am trying to install Windows 2008 R2 on a server with a 3TB HDD, but I can only create a 2TB partition on the hard drive, leaving around 800GB which I cannot even access. I can install Windows on the 2TB partition, but even after installation, I cannot
physically access the remaining 800GB. When I right click on the 800GB unallocated partition in Storage\Disk Manager, I have no options to create a new partition. If I right-click on the existing 2TB partition, I have no option to extend it using the remaining
800GB.
Motherboard details:
Asus Veriton S460
Product Name: EG31M
System BIOS: R01-C2
BIOS Release Date: 11/27/08
Can I do anything to use the remaining 800GB?
Thanks.

Known Issues/Limitations
Because the transition to a single-disk capacity of greater than 2 TB has occurred fairly recently, Microsoft has investigated how
Windows supports these large disks. The results reveal several issues that apply to all versions of Windows earlier than and including Windows 7 with Service Pack 1 and Windows Server 2008 R2 with Service Pack 1.
To this point, the following incorrect behavior is known to occur when Windows handles single-disk storage capacity of greater than 2 TB:
The numeric capacity beyond 2 TB overflows. This results in the system being able to address only the capacity beyond 2 TB. For example, on a 3 TB disk, the available capacity may be only 1 TB.
The numeric capacity beyond 2 TB is truncated. This results in no more than 2 TB of addressable space. For example, on a 3 TB disk, the available capacity may be only 2 TB.
The storage device is not detected correctly. In this case, it is not displayed in either the Device Manager or Disk Management windows.
Many storage controller manufacturers offer updated drivers that provide support for storage capacities of more than 2 TB. Contact your
storage controller manufacturer or OEM to determine what downloadable support is available for single-disk capacities that are greater than 2 TB.

Hard drive only shows 32gb

Hi,
I own a HP Pavilion dv6830us laptop w/ Windows Vista Home Premium purchased a couple years ago. The original WD25--BEVS hard drive failed. I purchased a WD Scorpio Black 500GB WD5000BPKT to replace. Installed both recovery discs purchased from HP. Upon entering Windows after the recovery, a window popped up and said "Unrecoverable Error Has Occured" and prompted me to shut off the laptop. This would happen every time I restarted the computer. Eventually I realized it was the HP File Based Installer program that was causing this, so I managed to get to msconfig before the message popped up, and disable it from the startup. Now I am left with a Windows install with absolutely no additional software on it.
That said, I was frustrated but content with just re-installing everything. Then I discovered that Windows shows the hard drive as 32 gigs, with less than a gig free. I downloaded the BIOS update from HP. Then I downloaded the Western Digital Diagnostics software, and under the Physical Drive box, it recognizes the model and its potential capacity (500gb). Under the Logical Drive box, it shows File System NFTS, total space 34.37gb, and 1.05 gb free space.
I would like to know how to solve this issue, as this whole process has taken over 2 months and honestly it's been a nightmare. If anyone could point me in the right direction I'd be thankful.
This question was solved.

The following Microsoft link should help, please remember when extending a partition make sure you have a backup of all your programs and data first. There is always the chance that something could fail and with it being your primary drive you could lose everything.
This link is for Win7 but it is very similar to what you would do with Vista:
http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/how-do-i-extend-the-volume-of...
The below instructions are in the link provided and is the info from it that you will need.
Extending Windows 7 Partitions or Volumes
This section will show you have to extend a Windows volume. In order to do this we must open the Disk Management tool where we can resize our volumes. The following steps will walk you through this process.
Click on the Start Menu button in the lower left of your desktop and then click on the Control Panel menu option.
When the Control Panel opens, click on the System and Maintenance category.
When the System and Maintenance category opens, scroll down and click on Administrative Tools.
Double-click on the Computer Management icon. The Computer Management console will now be open. Towards the bottom you will see a category called Storage and underneath that category will be the Disk Management icon as shown below.
Click once on the Disk Management icon and you will now be in the Disk Management utility as shown in the figure below. From this utility you can see all the partitions on your computer and format, delete, create, expand, or resize them. For this tutorial, I am going to expand the E: partition so that it uses up the rest of the available space on Disk 1.
To expand the partition, you simply need to right click on the partition you want to work with and select the Extend option. In this example, I right click on the E: partition and in the menu that comes up I select Extend.
A wizard screen will appear as shown below. Press the Next button to continue.
A new screen, shown below, will appear that allows you to select the available free space on your local drives that you can use to extend the space of the selected partition. It is important to note that Windows 7 allows you to extend a volume using free space on the same drive as well as other drives. I strongly suggest that you do not extend a volume on one disk with free space from another. This is because if one of the drives has a hardware failure, then all the data on that volume will be deleted. Instead only use the free space on a drive that contains the volume you are extending
As discussed in step 5, for this tutorial we are going to expand my 8 GB partition (E: drive) to the full size of Disk 1 using all of its available space. As Disk 1 is the only available free space on my computer, windows 7 will automatically select it as shown in the image above and use the maximum amount available to extend the partition. If there were other drives with free space they would be shown under the Available selection. If you want to extend the volume by a lower amount you can change it in the Select the amount of space in MB: field. Otherwise we press the Next button.
You will now be presented with a confirmation screen. If you are sure you want to extend the volume, press the Finish button. Otherwise, press the Back button to make changes or the Cancel button to cancel this operation.
When Windows 7 has completed extending the volume, you will be back at the Disk Management screen where you will see the volume you extended with the new size. An example of this is shown below.
At this point you can close the Computer Management window as your task is complete.
Hope this information is helpful.
Let me know if this worked.

After creating a new login (bought computer used) and deleting the old one the 500gb hard drive only shows up as 320gb.

So I've just purchased a mid 2011 Macbook Pro 13" used via eBay. Was advertised as having 500gb hard drive and 6gb ram. I checked the ram and it was all legit, checked the hd capacity and it was all correct as well. So I made a new login for myself and deleted the previous owner's. Now my hard drive shows up as 320gb. Even in disk utility and terminal.

One more place to look is SYSTEM PROFILER>HARDWARE>SERIAL-ATA. If it says 320, you have a 320GB HDD which I suspect it probably will. They are easy to replace.

My HD-EG5 hard drive only shows me 99 mb of blank space after installing the App lock feature. ??

Upon installing the HD-EG5 500gig Hard Drive & installing the app lock feature, I was prompted to unplug & replug the drive in. When I did all that showed up was a 99 mb section called App unlock. After checking the drive at the most basic level, I can see the other 460+ gig using external software but it cannot be seen when you plug the drive into a USB port.

Travis,
I suggest that you format the hard drive in FAT32 format to resolve the issue.

160GB Native Hard Drive Only Showing 78GB

Hey all I hope someone can help because this is driving me nuts
I had a Macbook I got in 2008 and at some point (( while the computer was still in warrenty )) the hard drive dropped to 80GB's so I decided to upgrade it thinking I origionally only had 80GB
So I have had this hard drive ever since that is meant to be 160GB but is currently only 80GB ish
I have tried loading it through a PC, formatting it through the PC
Tried multiple times to run error checker through Disk Utility on the Mac
It is really bugging me because this is a really handy little hard drive to have around, what am I to do? please help
Thank you

When I received a second-hand MacBook a few years ago, the hard drive appeared to be an 80GB but really was twice that size. I sought to repair the situation as I've done on dozens of other older Macs over the past decade or so, but found it rather odd when I found out indirectly it was also a much larger size drive.
Turns out I had to reformat the disk using the booted version of Disk Utility in order to get the full capacity restored for the OS X to use. And in this instance, the issue was determined by me to have been due to a previous owner having incorrectly deleted the partition they'd created in OS X to boot into Windows. The BootCamp software had been used, and that would've been required to be used again to correctly remove the partition, in this instance. I didn't have it.
And if you do replace the hard drive to get a better larger faster one, also acquire an external enclosure for the one in the Mac now. It may be repaired through software, or it may have sector damage that is beyond help through use of Disk Utility; but there are third-party utilities, at retail, for technical repairs.
The error checking and repairs in Disk Utility won't do much unless the system is not running on the drive; so by booting from the install DVD (or a external clone, or backup, or recovery partition, etc) and unmounting the computer's drive, it could be repaired by that utility. If you make a bootable system clone, be sure to test the viability of a clone (should start the computer easily) before an attempt to secure erase + reformat a HDD.
{edited to move words around}
Good luck & happy computing!

300GB hard drive only shows... 120GBs?!?

I tried installing a 300GB seagate into my snow iMac, but realized only after installing OS 10.4 that the snow iMacs can only recognize 120GBs.
So I pulled the drive out and stuck it into an external firewire case. The thought was to try a 3 part partition of 100GBs each.
But after erasing the drive connected through an external firewire connected to my G5, I noticed the drive was still reading 120GBs. Even though I had just erased it.
I tried zeroing out the drive, the 7 pass erase, even the 35 pass, but they all fail within seconds of starting.
I even pulled out the master jumper, but still no change in the drive's size. It appears to be stuck at 120GBs.
Anyone know how I can get this thing back to 300?

Yes, any Mac that followed the new standard mentioned by this article should recognize more than 120 GB:

In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.

Windows Server 2012r2 Essentials - Dashboard - Server Folder and Hard Drives Not Showing..

Hi,
Following the last series of Windows updates, I'm experiencing problems with our WS2012R2 Essentials server. When opening the Dashboard, the 'home:getting started' tab shows all correct except 'server folders n/a'. On checking the Storage tab, the normal
display for 'server folders' and 'hard drives' just shows 'refreshing list of items'.
Despite symptoms above, Storage Space and Server Folders show correctly in server Windows Explorer and are available to client computers across the LAN. It just appears that for some reason the Dashboard cannot see them.
One other related symptom I've noted is that for some reason the 'wsestoragesvc' Windows Server Essentials Storage Service no longer starts automatically. Even when started manually Dashboard symptoms remain - server folders and hard drives aren't visible
on dashboard.
I've run sfc /scannow to check for problems - all clear and run chkdsk on the system volume.
Would welcome ideas on what steps to be taken to fix problem. Many thanks..

Hi,
The issue could be due to a custom service knocks on effect on the Windows Server Essentials Storage Service and causes the service no longer starts automatically.
You could refer to the thread below to troubleshoot the issue:

3TB hard drive

I have an interesting problem that I have searched a very long time for and have not yet found an answer..
I have a 3TB WD Elements drive, it works fine, loaded it with about 2.5tb worth of data. Plugged it into my linksys E4200 router as a storage device, found out the router doesn't support 3TB (it only displayed as 746gb on the router). So I safely
removed it from the router, then plugged it into back into my computer. Now it says in windows that it is a 746gb drive. In Disk management it says it is a 3tb hard drive, but windows explorer says it is 746gb. So, I know the router didn't
reformat the drive to 746gb, so what is up with windows only showing it as a 746gb drive?
Ive reinstalled drivers for the drive, updated intel rapid storage, and messed with other random things but have not come up with a solution yet. Any help would be greatly appreciated. I don't want to reformat it because I have so much data on
there it that reformating would be last resort.

@Vegan
Fanatic
You've
listed your rig- v. impressive but I understand nothing - presumably it's UEFI with GPT drives - making them bootable from said drive/s
The discussion in play is MBR - Its limitations and how to deploy excess from 2TB net (2.2TB gross)
If you require one Partition of 3 or 4 TB, then GPT on a MBR BIOS PC will do it, but you cannot Boot from it However, 746GB or 1617GB
excess can be allocated with Seagate DiscWizard/Acronis True Image WD EXTENDED CAPACITY MANAGER, freely available for Seagate, Maxtor, WD Drives -WARNING - Do Not Attempt without FULL BACKUP (On another Physical Drive)
TIP - Your Restored O/S or the one's in situ will only see Extended Partition if DiscWizard/Acronis T.I. WD is installed - installs driver that makes this possible
Useful Tools - WD Mybook USB3 2TB/3TB
Seagate DiscWizard/Acronis True Image WD
BOOT CD (Created from within DiscWizard/ATI) Parttition Mini Tool/Easus Partition manager (Have both, sometimes one will do what the other won't allow)
EasyBCD - essential for MultiBooting inc, Linux
'"that
talks about a freeware, but then you are way off and in bad territory" thus speaks an officianado with many points to his name. The only risk you're taking is by not Backing Up - or Backing up on the Drive you're working on - Software supplied by Seagate
and WD, although free cannot be regarded as 'third party', Storage is their business and is very flexible - clear what you've backed up and where backups are stored
'Today's Third Party Software is tomorrow's Ist Party feature in an O/S'
The
storage released in this way can only used as storage - create partition/s in normal way - NO Booting from this 'Drive' within a physical drive
Let me know, if there's anybody out there that needs an O/S Partition greater than > 2TB
Second point:
'I
have used old machines for NAS use fine. Linux and Windows can both be used.'
My question is were any of the NAS drive/s over 2TB net and did you plug them into a Router, which was
the scenario in play ? And what was the interface between NAS and PC, how fast did Linux and Windows boot from NAS compared to O/S on native SATA drive ?

Is a WD My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive bootable with my Powerbook G4 12" PPC 10.5.8?

Sirs or madams,
Is my Powerbook G4 12” PPC 10.5.8 'bootable' with a Western Digital My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive? Western Digital says officially no, but that it MIGHT be. I primarily live in China and bought a datastorage.com.cn Clearlight s400+ external hard drive enclosure with a 320GB disk drive a few years ago in China. My computer 'boots' fine from it, but since I got it in China all the paperwork, etc. is in Chinese; my Chinese isn't quite sufficient enough yet to read it. But there are references to something called "SATA", whatever that is.
My level of computer 'under the hood' knowledge is extremely low. I've been told that SATA has some relationship as to whether or not an external hard drive will boot a computer via the Firewire connection, something relating to 'interface', which I assume is how separate electronic gadgets work, or don't work, with each other.
I frankly don't care much for computers, the internet, or their related gadgets such as all these fancy phones. I longingly reminisce about the days when there were no such things. I use a computer & the internet because I have to, and unfortunately unlike a car where one doesn't have to have 'under the hood' knowledge to operate it, just knowledge of the steering wheel, brake, gas, etc., one seemingly must know a ridiculously great amount of 'under the hood' knowledge, including jargon, to operate computers.
So, please try to respond accordingly; thank you.
If this particular external hard drive won't, for certain, be bootable with my computer, can you advise as to what readily available brand/model would be in the 3TB range for a similar price, roughly $150ish??
Thank you very much.

Mr. BGreg,
Thank you very much. "...under the covers...". I think you meant "under the hood", as in a car. I suppose "under the covers" would be man/woman interfacing, which I am familiar with!
Actually, I'm back in the US now for a few months. I looked at the OWC web site, but only cusorily so far. I'll contact them; they appear knowledgeable about Apple computers.
As to what you wrote about Western Digital's cases, I certainly wouldn't want a poor case. In China I had over time gotten 3 different external drive cases, 3 different Chinese brands, and separately bought Hitachi brand disk drives that 'simply' plugged into the cases. The drives are roughly 80GB 120GB and 320GB. The two larger ones are in cases that have Firewire plugs/jacks, which are bootable with my computer.
So my understanding, as you wrote, has been that my Powerbook will boot from an external hard drive, provided it connects via Firewire, and the disk drive itself is 'normally' formatted with however my computer's own disk drive is formatted, (HFS OS extended (journaled) or some such??). So I was left wondering why Western Digital would indicate that even though their such-and-so external hard drive case/drive was Firewire capable, that they would then say it would not be bootable with my Apple PPC computer......
Well, anyway, since you indicated Western Digital's case quality is suspect, then I'll try OWC and disregard Western Digital.
Naturally, OWC should be able to address this, but your thoughts are also welcome. You mentioned the OWC cases are good with Apples. Would the disk drives OWC supplied with the cases also be of relatively dependable quality?? From my so far only cursory look at their web site they appear to have various options, including case only options where I could insert my own or their own drives. These sorts of options seem preferable, also along with quality components.
My Powerbook has been in use since 2004. In China I put in a 1.25 memory 'chip' in the bottom and installed the 10.5.8 operating system, which I understand are the maximum workable with my Powerbook. When I inquired with Chinese friends if my 1.33 GHz processor could be taken out and a more powerful one put in, they said it wasn't feasible because in my particular computer my processor was, as I recall them saying, soldered/'permanently' connected with the 'motherboard', that it would just be easier to get a new computer.
I would be with them and they would nonchalantly open it completely up showing me all its tightly arranged 'innards' while at least giving it a good internal dust/dirt clean job for cheap lunch and a beer (& so much dirt/dust/lint there was!)...these are the same folks who build the things of course...fast moving hands with tiny screws flying everywhere, but everything 100% all back in place when finished.
My Chinese friends also said that nowadays Apples are not as well built as when my Powerbook was built, that nowadays an Apple's life expectancy was considerably lower, so I fear that when I get a new computer that, though it will be more up-to-date and powerful, etc., it most probably won't last near as long as my Powerbook has. They also said that in an older computer the fan was often the first component to go bad, and if a new one couldn't be easily found, as they said was my case, then you're just left with having to get an entirely new computer. Part of why I dislike electronic computer gadgets generally is that they are obsolete so quickly.
So, anyway, thanks very much for your information.

I just installed a 3TB hard drive on an early 2008 mac pro and it is not recognized/not visible. What now?

If the drive is correctly installed on to the sled, and the mounting screws are snug, not tight, and the sled is inserted properly so that all the roof-tangs catch as the sled is inserted, failure to show up in Disk Utility means the drive is not useable.
A Bug in 10.8.4 and later precludes Disk Utility ERASE-ing large drives in Internal bays. Use PARTITION only, and create one new partition, GUID partition Map, Mac OS Extended (journaled) Volume.

Will k8n sli platinum support 3TB hard drives

Folks,
will the k8n sli platinum motherboard support 3TB hard drives? I have a 3TB hard drive that displays as 746GB. Latest bios is on board and running win7 64bit.
Many thanks
Dave

in the BIOS it states 3TB under the hard drive section, however that might just mean it's reading the drives properties and not it's capabilities if you know what I mean.
In the motherboards raid setup only 746GB on each drive is available and within Windows only 746GB is available.
I've read somewhere that's it's got something to do with 32bit "storage" hardware systems only being able to address 2.2GB or close to that. I think I'm gonna have to upgrade.
cheers
Dave
