WinUSB Maker Didn't Finish, Now USB is unrecognizable

Miniia,
Welcome to SevenForums.

Help us to help you by filling out your System Specs and here is how:
Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

And here is how to prepare a UFD (a usb stick):


PREPARE A UFD/SSD/HDD FOR USE


UFD = USB Flash Device, such as, pen drive, thumb drive, usb stick.

Run CMD.EXE as administrator
Ctrl + Esc | type Cmd in the “Search Box’ | do not hit Enter |
right-click on CMD.EXE in the list of Programs | YES button (if asked)

Use DiskPart ----{type commands, follow each by hitting ENTER}
Type DISKPART ------{starts DiskPart; command prompt changes to DISKPART> }
Enter following DISKPART commands:
List disk ----------{list number assigned by DiskPart to the drives;
-------------------- note the numeral assigned to your UFD/SSD/HDD}
select disk 1 ------{the numeral 1 will be used in this example}
detail disk --------{info will help verify that you’ve selected the desired disk}
clean all ----------{write zeroes to all bytes of selected disk; depending upon
-------------------- capacity and device speed, this can take awhile.
-------------------- Any bad sectors will be so marked and avoided.
-------------------- Wait for the DiskPart prompt to appear again.
-------------------- The DiskPart> prompt will eventually appear.
OR--OR--OR--OR
clean --------------{zeroes only first and last sectors to zero out boot info;
-------------------- This is much quicker and suffices for most cases. }
If installing Win 7 to a SSD/HDD,
AND you want to let the Win 7 installer create partitions, then
go directly to the EXIT statements.
create partition primary -{create a primary partition in the selected disk}
select partition 1 -------{select the partition you just created}
active -------------------{mark the partition as Active, ie, a system bootable partition}
format fs=ntfs quick -----{format the partition as ntfs}
assign -------------------{assign next available drive letter to the volume}
exit ---------------------{exit DISKPART and return to the command-shell prompt}
exit ---------------------{exit the command shell }

Try using another usb port on your computer.
Try the stick on another computer.

The USB should show up.

In any case, if the usb stick is not recognized in any usb port on your computer and also on another computer, diskpart does not see the usb stick, you can throw the usb stick in the trash.

One last ditch attempt.
