I am trying to set up an external drive for backup purposes.

I select the partition that I want to modify but all the options are greyed out and I cannot therefore assign a drive letter. I am using an administrator account. How do I proceed?

Are you using the built-in Disk Management tool or a 3rd party program?

You can if you want to use third-party partition manager.

The problem is that "Initialize Disk" and all other options are greyed out and cannot be accessed

1) have you tried to Intialize the disk as @FreeBooter mentioned?

2) if you have and it is still greyed out, can you open Command Prompt as Admin, run

Code:
diskpart
{Enter}
Code:
list disk
{Enter}

and post a screenshot of the output here please?

just to verify before providing anymore instructions... is there any data on that drive that you need/want to keep? in your initial post, you had stated "partition", but am wondering if you meant "disk" that you want to use for backups. if you don't have data that you want to keep, i can proceed to provide more instructions.

ok. open command prompt as admin and run the follow commands:

Code:
list disk
select disk #
format fs=ntfs label=Backup
assign letter=D

replace # with number of disk you want here (would be 1 based on your other screenshot)

yes, those all appear to be on Disk 0. the disk you attempting to use may be going bad. but lets try this to see if it will recognize the ability to initialize / format it. download and extract Minitool Portable Partition Magic and run the 'partitionwizard.exe' file in the extracted folder.

download links to 32 & 64bit are under step #2

OK - did that and the create command finished successfully. But No change - partition options still grayed out

parition magic created a partition on the disk and you clicked "apply" and it said successful, but the disk is still not showing properly? did you "rescan disks" in disk management after running partition magic?

Hi,

It is a GPT Protective Partition.
Search what it is and how to get rid off it.
The explanation is on the EaseUS web site.

Ciao, Han
