    Hi there

    Trouble is people are afraid to use the command line these days.

    1) Stick your USB into the W10 machine
    2) ensure there's no messages or format requests.

    Now use the CMD PROMPT in administrator mode and type the following.

    DISKPART
    LIST DISK (say the USB stick is drive 5)
    SELECT DISK 5
    CLEAN
    CREATE PARTITION PRIMARY
    FORMAT FS=NTFS QUICK
    ACTIVE
    ASSIGN

    EXIT.

    If you get an error at CLEAN simply ensure you don't have file explorer or control panel open and try again.

    Cheers

    That "should" be automatic, but I have seen that happen every once in a while. One thing is the newer Sandisk thumb drives show up as fixed disks instead of removable media. I don't know why Sandisk did this or what the ramifications are. On the plus side it makes it easy to use those drives for Windows To Go. Assuming you have one large enough.
    It's an 8GB and edited my post to reflect that. One would think it to be automatic, but for the life of me it wouldn't show up. I bought it specifically for my 10 ISO install and wasn't sure to format it or not to prep for ISO install. I haven't for DVDs. Basically right click and direct to burn to optical drive D:. I used the Windows 7 USB/DVD Download Tool for the thumb, but it could not see the drive. I scrapped that and burned to DVD in which I had trouble. It turned out that my PSU was on it's way out, so at that time I accredited it to the bad PSU.

    Anywho, after up and running again, I saw it in 8.1 Disk Management, but with no letter assigned. After assigning a letter it worked fine.

    Just make sure you select the correct drive. The clean command will wipe that drive of all data.

    Thanks everyone for responding.
    I'm in a new ballpark.... Can't find Cmd Mode or Administrator...
    Will keep looking. Maybe I'll get lucky...

    Also my Sandisk drive is a letter and not a number.

    You may be on to something regarding the flash drive in Windows 10.

    I took a 4 GB flash drive and went through the Diskpart commands on Windows 7, 8.1 and 10. The commands on Windows 7 and 8.1 worked fine, but this is what I got on Windows 10.

    After I got the indications below, I removed the drive and reinserted in another USB port. The commands were successful this time as shown below..Edit: It turns out the partition created, even though successful, was not valid on an 8.1 system.

    DISKPART> list disk

    Disk ### Status Size Free Dyn Gpt
    -------- ------------- ------- ------- --- ---
    Disk 0 Online 223 GB 1024 KB *
    Disk 1 Online 238 GB 1024 KB *
    Disk 2 Online 1863 GB 1024 KB *
    Disk 3 Online 3823 MB 0 B

    DISKPART> sel dis 3

    Disk 3 is now the selected disk.

    DISKPART> clean

    DiskPart has encountered an error: Access is denied.
    See the System Event Log for more information.
    The Event Viewer shows this:
    Cannot zero sectors on disk \\?\PhysicalDrive3. Error code: 5@0101000F
    The source is the VDS Basic Provider.

    Since I do not know exactly what this means, I will have to do some checking. As far as I know, nothing was open that was accessing the drive, not even Explorer. I do notice in Explorer the drive shows under "This PC" and as a separate entry on the same level as Network and This PC. Whether the "This PC" listing is expanded to show this drive does seem to make a difference as to whether the drive is accessible.....

    DiskPart succeeded in cleaning the disk.

    DISKPART> create par primary

    DiskPart succeeded in creating the specified partition.

    DISKPART> format quick fs=fat32

    100 percent completed

    DiskPart successfully formatted the volume.

    More info on my previous post. After I tried to use the drive after Diskpart appears to have succeeded, I got a message about inserting a drive, so it was not accessible. When I went into Disk Management, the drive showed as unallocated.

    When I tried to add a partition in Disk Management, I got the options below. I don't think the NTFS option should be missing, or FAT should be the default format type.... Sorry the snipping tool will not allow me to show the options for formatting, but FAT and FAT32 are the only options.

    I'm pretty sure FAT is the default for any blank thumb drive I've used. It should default to FAT32 for larger drives. NTFS should be listed though, it is for me?

    It may depend on the size of the drive what shows as primary, but when I put the drive on the 8.1 system it showed Fat32 and default and NTFS and exFAT along with FAT, after I switched the port it was plugged into.

    I have just done the same procedure with a Patriot 32 GB USB 3.0 drive and that drives seems to behave the way I would expect. So far no problems in Windows 10 or 8.1.

    I probably need to clean several of my USB drives, so I will check each one as I clean it. Maybe the original 4 GB drive (Verbatim) is not compatible although the Microsoft listing shows it is with 8.1.
