Windows 7: Cannot merge unallocated hard drive space

Cannot merge unallocated hard drive space

So I got a new unused external hard drive, I was trying to partition it and ended up accidentally making half of it unallocated. I was trying to merge it back together but all the options like extend volume or make new simple volume are all greyed out. Anybody know what might be happening? Maybe you've got a solution? I would greatly appreciate any help.

Have you given the external drive a drive letter?

What tool did you use to partition it?

Might be useful if you posted a screen shot of Windows Disk Management.

Hello teoni!

Do you already put data on the first partition you made? If not, you could simply delete it and then recreate the partition onto the whole drive, if that is what you want. :)

Otherwise, if you are using Disk Management, it could be some limitations that are preventing you from Extending the Partition or anything else. You could try a third party program for that.

Please post a screenshot like ignatzatsonic asked, of Disk Management.

Cheers! :)

unallocated hard drive space
I have a 5610Z Acer Aspire with Windows 7 (32 bit). I pulled a very boneheaded move getting to upgrade from Vista. I deleted my D:drive (50 G). I back up to a 500 G external hard drive. Is there a way to add the 59G to C:drive where I could use the space. Thanks Brightlight864:o
