Disk management shows different drive capacity from windows explorer

[dclong]

I have a 2TB Seagate hard drive. Disk Management correctly shows a capacity of 1863.01 GB available space.

Windows Explorer, on the other hand hand, shows a total capacity of 181 GB.

Any advice would be tremendously appreciated!

Thanks,

Daniel

easy, fast and worked for me.

Sorry if redundant because I didn't read the whole article.

Had the same problem - used fsextend and it corrected the partitions so they finally showed correctly Just thought I'd update the thread since it came up in my searches for the same problem.

I know how much fun it is to scroll through loads of threads just to find that everyone else had the same problem but no one bothered to post what worked

I'm editing my earlier post, as I now realize my problem is slightly different than the OP's. I've found that some differences in drive size between Disk Manager and Win Explorer is due to inconsistent use of units as described on the "binary prefixes" page in wikipedia. It's about a third of the way down the page, but that explained a lot. As HD's get bigger, this "anomaly" will confuse a lot of people.

see this article:

http://blog.jstudios.us/post/2010/07/02/I-Expanded-the-Disk-in-Disk-Manager-but-It-Doesne28099t-Show-in-Windows-Explorer.aspx

right clicking on the console option to open as administrator, I did these commands as the article says, to resolve the difference in the size shown for my c-disk partition in disk management and windows explorer (Windows 7):

At a command prompt you need to enter the following:

C:\ > DISKPART
DISKPART> List Volume
DISKPART> select volume # (this is the number of the volume listed by the above ‘List Volume’ command)
DISKPART> extend filesystem
DISKPART> exit

Now Windows Explorer shows the new expanded size of the disk.

Really old post but since no real solution is posted so i felt that i needed too .

First, there is no problem at all, disk vendors market their drives as 2TB/3TB etc and their model is based on that one megabyte/gigabyte etc equals 1000 instead of the real technical factor of 1024, u can ask why they do so but there is no real answer other than it is a standard amongst disk vendors.

So in short words, operatingsystem uses the real factor 1TB = 1024GB while diskvendors says 1TB = 1000GB
thats why u see a smaller amount in your OS than printed out on the disk
