I formatted a usb external hard drive in linux with ext4 format.
In windows 7, I deleted all these partitions using disk management. Windows doesn't display the drive when I connect it.
How do I fix this?
Go to Control Panel. Choose Administrative Tools.
Choose Computer Management.
Navigate to Storage->Disk Management inside current window.
Now we have few possibilities:
Other options would depend on how the Storage tab looks like for you. It would help if you provide us some more information from this tab when external HDD is connected.
AFAIK in windows there's ( actually ) no way to use "native" ext4. You'll need external software ( like http://www.ext2fsd.com/ ) or whichever software you'll be able to find.
right click on my computer and open manage. now look for 'Storage'. I'm sure your hard disk will be visible there.
I'm taking a shot in the dark here, cause i don't really know how a format in linux is relevant vs a format in windows. But i'm going to just address how to install a hard disk after it is installed into a windows environment.
First make sure the drive is actually connected.
Right click on my computer > Properties > Device Manager
If the drive is found move on to the next step.
Control Panel > Administrative Tools > Computer Management > (Left Side) Storage > Disk Management.
At the bottom you will see all your physical drives. Go to the one that looks like:
Right click on that unallocated drive and Go to New simple volume:
goto Format this volume with the following settings: NTFS, Default, Name the volume, Make sure quick format is checked > Next.
Done. After this is complete, your drive should show up.
