I need to format my USB stick to NTFS, because tommorow new components should arrive and I need to reinstall Windows 7.

However it fails to format to NTFS, so I googled how to fix it, found some solutions with diskpart and EaseUS Partition Master, I tried the diskpart first but I stumbled when it showed that theres a 1 disc 1024GB which is the USB disc.
I'm for 100% sure that thing doesn't have 1TB storage, it has 8GB, it's even written on the cover. In compmgmt.msc and in EaseUS Partition Master it shows ~7.9GB allocated space and 1000GB+ unallocated space. Hows that possible?
I can't even delete that unallocated space.

How do I fix it and format it to NTFS correctly?

Windows 7 64 bit ultimate
USB some 8GB Kingstone that I found in a drawer.

I would open an elevated command prompt (right click run as admin) and then use the following diskpart commands with the USB stick attached:

diskpart
list disk
select disk n (be certain that you select the USB stick from the list disk command)
clean
exit

You can then use disk management to initialize/format to MBR,NTFS.

Tried that, still it didn't let me. But I finaly managed it to format it to NTFS through theEaseUS Partition Master, however once it was finished, windows explorer prompted me to format it again to read it. It got stuck and now it can't read the storage.
Now I can't fix it, because the Diskpart, Disk Managment and EaseUS Partition Master won't load up when the flash disk is connected...

I smashed that piece of crap to billion pieces and tommorow in the morning will have to get a new USB stick and hope it wont play any shenanigans on me again like this one...

It might have been a fake capacity drive, where the reprogrammed chip that gives the fake capacity went wrong.

Always check all new Flash based memory with h2testw.exe, even branded stuff, because fakes can get into the supply chain; I got 2 fake Samsung cards a couple of year ago via Amazon.

h2trestW is so good, various fake memory merchants try to claim it wont work on their "special" brand of memory card/usb drive, and that their fake capacities are really real.
