Hello,

I have a WD My Passport Ultra External Hard Drive 3TB. I formatted it to work with my PS4 and now I want to use it on my HP2000 laptop again. The only problem is, it now has a partition in it and I only have 1.8 TB available of a 3 TB Hard Drive. How do I totally reformat all 3TB and put back to factory defaults?



Thank You

You can either format it through Disk manager by deleting all partitions or using the following commands from a command prompt and pressing enter key after each one.

Type diskpart
list disk
select disk 0 (or the correct disk you want to format) Be very careful you select the correct disk)
clean
convert gpt
create partition
format quick fs=ntfs
assign
exit

When I type Disk 0 and hit enter, a lot of script comes up. When I type Clean, it tells me no disk selected.

I'm also not sure how to use Disk Manager. I see it has 1,800 MB of unallocated space

After you type list disk this will show you list of drives that you have connected with numbers. Then you use select disk with the correct # of the drive you want to format. It is very important that you select the correct drive and do not format your main drive or other drive. If you have any questions about which to choose please provide a screenshot and ask before proc

To use the whole disk as one partition you will have to convert it to GPT if it isn't already.

The link in post #3 by SpywareDr shows how to do it.

I have a WD My Passport Ultra 3TB External that I formatted to use with my PS4. I now want to use it on my HP2ooo again. It has a partition in it now and I can't seem to delete it. I went to MS DOS and entered DISKPART, select disk #, clean. It says "Virtual Disk Service error:
Clean is not allowed on the disk containing the current boot, system, pagefile, crashdump or hibernation volume."

I am not sure why you started a new reply. We need to make sure you are selecting the correct disk with diskpart. Please provide a screenshot or picture after running the following commands so we can verify

diskpart
list disk

I've selected zero. It is almost a TB. MY External HDD is 3 TB. The other 1800 shown is the rest of it.

Are you absolutely sure that is the correct drive. Usually zero is the boot drive and not an external drive. Please provide a screenshot as I asked or you can severely mess up your computer by choosing the wrong drive.

Ok you definitely do not want to select disk 0. You want to Select disk 1. follow the commands

Type diskpart
list disk
select disk 1
clean
convert gpt
create partition primary
format quick fs=ntfs
assign
exit
