Windows 10: Can't format external USB drive.

I am trying to format 2 partitions on an external 1TB USB3 drive. I had 2 ExFat partitions (partitions 6 and 7) which I have deleted and created 2 new ones using diskpart which I want to format NTFS.

When I try to format them using disk management it hangs, explorer crashes and I have to hard power off.

When I try diskpart I get the error "The parameter is incorrect. See the System Event Log for more information.". There is nothing to be seen at all in the system log.

Have I created the partition table incorrectly in some way? It was originally created manually using this utility GPT fdisk | SourceForge.net

The other partitions are working fine.

Hope this isn't true but Windows 10 File History Backup Support is not available to users?

This can't be true. File History Backup to External USB Drive was working fine but now needs help. I am now doing a full format on the External drive (takes a very long time) in hopes that this will fix problems. The quick format was quick but didn't
solve the problems. It seems when trying to do the backup it returns an error saying that the format of the drive is not NTSF, on a Network Drive, and etc. Please give some advice.

Windows 10 - formatting external drives to FAT16/32

Hello Brian, try this:

Format USB flash drive or external hard drive into FAT32 using CMD command line

A simple and free way to format your flash drive or external hard drive to FAT32 in brand new Windows 10 is using CMD command line, a built-in FAT32 format tool which enables you to format/create/delete/extend/shrink partition without rebooting the system.
If you want to use this tool to format the flash drive or external hard drive to FAT32, please try the following steps:

1. Open a command window by directly typing CDM in Windows 10 "Search the web and Windows" box. Windows 10 will show you the best match Command Prompt.

2. Type the command "format /FS:FAT32 H:" at the prompt. H is the drive letter of your USB or external hard drive in Windows 10. If it's not for your case, replace the drive letter H with your own letter.

3. Hit Enter. Windows 10 will go ahead and begin formatting the USB flash drive or external hard drive into FAT32.

Hello Adam,

Test with the command below instead to see if it may work. *Smile

FORMAT FS=NTFS /V=eGo /Q

 

Invalid syntax unfortunately.

PHP Code: DISKPART> FORMAT FS=NTFS /V=eGo /Q
The arguments specified for this command are not valid.
For more information on the command type: HELP FORMAT
I've confirmed it isn't the drive as I can format on another 8.1 computer. It isn't the USB hardware as when I boot this PC into OSX it works fine. In windows 10 the newly formatted NTFS partitions I can write to but not delete or copy big files so it isn't just formatting.

It is connecting through UAS which is new for me. I'll have to check the drivers, disabling the controller and so on I guess.

 

That looks like a W10 bug to me. I would report it.

 

I think so - I just need to work out what to say. It is connecting through here:

Things that connect through USB mass storage device work. Things that connect through USB attached SCSI don't. Every driver says "Driver version 10.0.9926.0"

It would be interesting to know if anyone else can connect to external drive using UAS and if it works if the drivers look like this (Right click on drive, Properties, Hardware tab, Properties, Driver tab, Driver Details)

Attachment 12930

Edit I've marked this thread solved and asked the same (hopefully more clearly) here Can anyone use USB attached SCSI in 10? *Smile
