What happened?

When trying to format my 128GB USB drive that had a seemingly broken installation of Ventoy (which I've now deemed as a broken USB drive), the entire installer froze around 18%. After a couple of minutes of waiting, I gave up and unplugged the USB drive. After this, the installation quickly moved up to 100% and said it was completed, which I assumed was it just writing to the Windows USB cache or maybe just the installer had frozen during the install but wrote everything, as it obviously couldn't have written to the unplugged USB drive at that time.

Out of curiosity I clicked the drive list to see what it thought it was writing to, then my computer bluescreened. My computer has had some issues with random bluescreens recently (specifically the MEMORY_MANAGEMENT error code), so I didn't think to write down the error code or anything, but I now realize that it wasn't just a normal random bluescreen. Oddly, there's also no log in the C:\Windows\Minidump folder, which I have no idea the cause of.

I'm dual booting Linux so I went to my boot devices to boot into Windows because I don't like waiting for grub to open, when I saw a new entry for a "UEFI OS", I booted into it out of curiosity and realized almost after that in parenthesis it said (SATA:) and then saw an empty Ventoy UI show up and my heart dropped. I reset my computer and booted into Windows:

The fact that it only made a 128GB partition and not the full 2TB definitely points to this being a bug from some kind of drive failover or something. I had enabled "Show all drives" before imaging just messing around in options, but I disabled it after.

Not too sure what else to say. Gonna go install systemrescuecd on another USB drive and hope for the best...

tldr: 2tb go byebye (sorry about all the yap, just wanted to give a story with the information)

i've read at least two horror stories just like this.

because of that, I make sure to install Ventoy in VirtualBox (using Ventoy Live ISO) from now on. it can set what USB devices are opened inside the virtual space, so I only add my disposable USB flash disk.
