    I had a 200 GB HD which became defective. I was able to fully back up all the data on an external USB drive. I bought a Western Digital WDC2500SB EIDE drive which is 250 GB. When I went to restore the data from the Toshiba USB drive I made a wrong selection and although all the data and OS was intact the drive only shows 189 GB total capacity in My Computer. I can back up onto the external USB drive. My question is "How can I format or whatever to utilize the full space on the WDC (250 GB)?"
    I use the EaseUS backup freeware on the Toshiba USB drive.

    It's pretty normal that you wont have access to the full amount of space declared on the box of your hdd. But 189GB / 250GB seems strange.

    I assume you are running a windows machine? Can you open "Disk Management" for me? Clicking start and then typing that into the search bar should bring it up. On the bottom part of the window you should see one or more disks. Take a look at your 250GB disk. Does it actually say 250GB? And if that is the case: Is there any unallocated space on the right side of the disk?

    Edit: I just realized you posted in WindowsXP. I don't have an XP machine but i found these directions to open Diskmanagement on XP:

    Hoping I can help, Micrologist

    I understand what you are saying about not having the full number of bytes available. The problem happened when I apparently chose to allocate the new WDC disk to only the size of the old HD. In Computer Management it shows 189.91 GB NTFS with 42.97 GB unallocated. I would like to use this unallocated space as drive C:
    Thank you for your reply. How do I access the 42.97 GB?

    I'm just trying to reproduce your setup with an old HDD. Im going to edit my post as soon as I figured out the best way to use the unallocated space.

    Edit: Just checked the Disk Manager with a primary partition and some unallocated space. Assuming the XP Disk Manager is similar to the newer ones those are your options:

    You can either create a second partition (D:\) out of this Unallocated Space by right clicking the Unallocated Space and clicking "Create Partition" or
    extend your existing partition (C:\) by right clicking the existing partition and selecting "Extend Volume".

    Needless to say you should have a backup of your data when fiddling around with partitions.

    I would suggest downloading the Minitool Partition Wizard , installing it on your Windows computer, and have it increase the size of the C: partition.
    It is one of the only tools that can change the primary partition in a running OS.
    You highlight the C: partition block, and click Move/Resize in the top menu set of icons.

    After you are done with that, click the Bootable CD button and download the .iso file to burn a bootable CD.
    It may be very handy later.

    I agree that this is probably the best method. But I was just wondering: Doesn't the Windows Diskmanagement Support extending a primary partition? Or is this limited to a partition that doesn't contain Windows System files?

    I'm pretty sure, FWIW, that even the lame Windows Disk Management can extend any partition if there is unallocated space to the right of it.

    You can possibly do this in Win7, if there is unallocated space immediately above C: on the disk.
    Win XP Home will not do it.
    Not sure about WinXP Pro
    But Minitool Partition Wizard is free, and it will do it..

    Thank you for the response and recommending Minitool Partition Wizard. I was able to resize the C:\ partition and now have access to the full size of the drive. The process was painless and quick.
