Undoing mem test usb

danlightbulb · 4 May 2017 at 14:50

Hi

I have a USB stick with mem test on it. The installation of mem test did something to the USB stick and reduced its available capacity. I want to restore the USB to original size. Any ideas?

Thanks.

try the following

load command prompt and try the following

1. type diskpart
2. list disk
3. select disk # (make sure you select the USB drive)
4. clean
5. create partition primary
6. select partition 1
7. active
8. format FS=NTFS label=USB Stick
9. exit

Try reformatting the usb through windows and that should clear it back to full size.

There's also a nice GUI for this kind of thing, type diskmgmt.msc (or navigate to it many other ways, e.g. start, right click on computer, manage, Storage, or something like that).

Need to use diskpart and the clean command as already stated, windows disk management wont delete the memtest partition.
