What happened?
I prepared a Corsair Voyager GTX SCSI USB drive for Ventoy using the Ventoy2Disk.exe utility with the following options:
- Secure Boot Support: Unchecked
- Partition Style: GPT
- Partition Configuration
- File System For Ventoy Partition: exFAT, NTFS
- Preserve some space at the end of the disk: Unchecked
- Align partitions with 4KB: Checked
I clicked the "Install" button and it created the Ventoy drive successfully. However, after unplugging and re-plugging in the USB drive, the USB drive's Ventoy partition takes forever to show in File Explorer and other programs. Sometimes, the Ventoy partition never shows up in File Explorer and other programs. Sometimes, I receive timeout errors by Windows and the USB LED light continuously flashes trying to mount the Ventoy partition in File Explorer.
Formatting this drive with only one partition allows the USB to mount successfully consistently. Tested unplugging and re-plugging and couldn't get the File Explorer hang delay to occur when the USB has one partition.

I have no idea about this. Let's ignore Ventoy for now, if you just create two partitions manually as Ventoy does, does it show in File Explorer OK?

I created a second partition using diskmgmt.msc on the corsair USB drive and attempted to unplug and re-plug the USB drive at least 10 times to try to reproduce the issue. Each of the 10 times, both USB partitions appear in File Explorer with no delay.
Is there anything else I can try to provide to help find the cause of this problem? Seems to only affect my USBs when they are formatted with the tool. Is there a manual configuration I can try running from the command prompt or powershell?
Try testing drive with fakeflashtest or h2testw or just filling it with video files and then playing first and last one. Sounds like a fake flash drive

Here's the result from h2testw after running the write+verify operation:
Can you try a different USB drive and also a different OS/PC? Many thousands of people use Ventoy without any problem, so this problem only seems to effect you. So it is probably something odd about your USB drive or system or maybe antivirus/antimalware software?
I tried with a different generic USB that is not as large, 2GB in size, and I could not reproduce the stalling/hang problem in File Explorer. I tried another USB flash drive, a Sandisk Extreme Pro USB 3.0 128GB, and the stalling/hang problem in file explorer returned. Tested both USBs on another computer with Windows 10 instead of Windows 11, and they too had the same stalling/hang problem.
So far, I am experiencing this issue with large capacity USB drives on Windows. The small capacity USBs mount instantly in File Explorer after Ventoy has formatted them.
What happens if you just use the default Ventoy options (run Ventoy2Disk.exe but do not change any options)? Are you using standard Windows 10 and 11 - Retail? Pro? any added software? Modified OS in any way? Can you think of how your Windows systems may be different from other peoples Windows systems?

I just got a replacement USB drive from Corsair to finally test this. I left all the default options for Ventoy2Disk.exe using release 1.0.84 and it still hangs on insertion. This is what my Windows 11 File Explorer looks like when Windows is trying to read and mount the drive letter:
It slowly fills up the gray bar with green until the mount operation times out. When it times out, the USB mounts the drive letter, F:, and I can save files to it normally. I can only reproduce this behavior when Ventoy2Disk.exe formats the drive.

I am using Windows 11 Education, retail channel. Yes, there is a lot of added software on this installation. In terms of OS modification, the only thing I can think of is the DisplayFusion Pro 9.9 software that could modify OS files. However, I'm not entirely sure if it does or not.

That's a good question. I have two monitors, wireless keyboard and mouse, 4 PCIe add-in cards, an nvme drive. I don't know, its nothing too crazy. I'm gonna install a clean installation of Windows 11, fully updated, with no third party software to see if I get the same behavior. I still need to try it on a different system other than mine. I won't be able to until we get closer to the end of this year.

Try this CI release to see whether it behave differently: https://github.com/ventoy/Ventoy/actions/runs/3720691355 https://www.ventoy.net/en/doc_github_ci.html

Tried the latest CI release and it still hangs on insertion. log.txt
Also, I got two new error messages when trying to access the drive in File Explorer and Initialize the drive from Diskmgmt after Ventoy formatted the drive:
After install Ventoy, manually reformat the Ventoy partition again with Windows disk manager.

I performed a manually reformat immediately after ventoy install, unplugged and re-plugged the USB. However, the USB still stalls on insertion.
When install Ventoy, try reserve large amount of space, for example, reserve 200GB.

Still, the USB drive has trouble mounting in a timely manner.
Also, here is a video representation of the issue I face (I only ever showed screenshots of the behavior): https://www.youtube.com/watch?v=TtZNdBrVGd0
Can you try a USB 2 port and all ports (front, rear, sides). If you dont have a USB 2 port, connect the USB drive to a USB 3 port using a USB 2 extension cable.

I have the ASUS PRIME Z690-P D4 motherboard in my system. I'm reviewing its manual and it says it has two USB 2 ports in the rear. I plugged in this USB drive into both and they make the USB drive appear immediately! I tried 8 times, 4 times each per USB 2 port, and each time it showed up in File Explorer right away.
Hmm, so if its my USB 3 ports that are causing it to hang, how should I go about fixing that?
Try ALL USB ports - there are also two USB 3 (blue) ports in the rear. Do they work? Try using a USB 2 cable in the USB 3 port - USB 3 PORT - USB 2 CABLE - USB 3 DRIVE You will need a USB 2 male-female cable. Again try ALL USB 2 and 3 ports. If you find rear usb 3 ports work ok but front usb 3 ports don't work then could be:
- You are using wrong mainboard pcb header connection for the front port module
- There is a design flaw in front usb cable or module, perhaps grounding or shielding issue.
- You have another usb device connected to front usb module which is causing electrical interference with usb 3 flash drive. E.g. Bluetooth or WiFi or wireless mouse/kbd dongle. If so, connect the 'bad' device to a rear usb port instead of the front usb module.

I was able to find a USB 2.0 male-female extension cable and plugged in my USB to it. I plugged the extended USB cable to every single USB port on my system (two Case USB 3.0 ports and two USB 2.0 ports, two USB 3.0 ports and the teal USB port all on the back of my motherboard.) For each insertion, I visually inspected the File Explorer GUI and watched for the Ventoy USB drive to appear. For all ports connected to using the USB 2.0 extension, the USB appeared in File Explorer GUI near instantly each time.
Sure, but what about two rear usb 3 ports without a cable?
Without the extension cable, my USB still hangs for minutes when I plug it into either USB 3.0 port at the rear of my motherboard.
That is surprising. can you disconnect ALL other USB devices and try it again. Even disconnect mouse and kbd if USB - you can still see how Explorer reacts.

I disconnected all other USB devices from my system and tried my USB into both rear USB 3.0 ports again:
I still encounter the same insertion hang in File Explorer GUI.
That's very strange! Maybe it is a driver problem? Or possibly some strange software you have installed? Usb 3 works at rates approx 2.4megahz and other devices can interfere with it but the rear usb 3 ports should be electronically well designed. Maybe some other device is causing a problem like PCI cards? Is your pc home built? Anything special about it? Cards, PSU, peripherals, ?

Yes, this PC is home built. It has standard hardware installed into the slots and USB ports. Peripherals include:
- Logitech - ERGO M575 mouse
- Logitech K350 keyboard
- Logitech unifying receiver (for mouse and keyboard)
- AudioEngine A2+ USB speakers
- TP-Link UH720 USB hub
- Xbox Wireless Adapter USB dongle
- Rodecaster Pro 2 USB connection
The power supply is a Seasonic PRIME TX-1000 PSU.
These are the cards in my system as it relates to PCI cards/NVMe drives
- Seagate FireCuda 530 NVMe
- EVGA GeForce RTX 3090 FTW3 ULTRA GAMING add-in card
- Intel Optane P5800X add-in card
- ASUS PCE-AX58BT wireless add-in card
- Corsair Force MP600 NVMe
- Elgato 4k60 PRO MK.2 capture add-in card
- Crucial SSD in SATA port
In addition, here's a diagram of what slots they are installed into:
Well the USB peripherals are irrelevant since you disconnected ALL of them and still got the problem.
Do you have a USB 3 male to female USB extension cable - you could try that too because sometimes the braid/screening in a good quality USB 3 cable can absorb the high frequency interference on the ground and data lines on a USB 3 device and can fix a conducted rf noise issue.
It could be a driver issue - maybe Optane driver? or ASUS PCE-AX58BT wireless add-in card may be causing a problem by generating electrical noise which is interfering with the USB 3 data I/O signals or ground..
Easiest thing to do is maybe just pull out the wireless card from the PCI slot - just as a test. If that doesn't fix then maybe uninstall the Optane driver?
After that, you will have to remove all of the other peripherals.
I think this has to do with I/O data corruption at fast USB 3 speeds but I am not sure what it is caused by.

I will give this a try and report my findings. In addition, I have another PC coming to me that is AMD-based to compare the behavior of what happens when I insert a Ventoy-formatted USB drive. I am going to have Windows 10 installed on the AMD PC, too, so I can compare if the OS version introduced a bug with my USB device.

While I wait for the PC to arrive, I went ahead and installed a new copy of Windows 10 64-bit Version 22H2 on the Corsair NVMe. I fully updated the Windows OS to the latest build version (Windows 10 22H2, OS Build 19045.2364) and tried my ventoy formatted USB again. Each time I inserted the Ventoy USB in this copy of Windows 10, it came up immediately in File Explorer, no delay or error.
Perhaps my issue is software related? I tried the USB in Safe Mode on my Windows 11 installation and it still exhibited the same behavior. I am not sure if perhaps my Windows 11 installation has some corruption somewhere for it to persist within Safe Mode. I will continue to try different combinations of configuration.
Windows 11 22H2 has a bug where file transfer speeds are slower than they should be. Maybe that's causing the drive to take so long to show up? Either that, or you have some sort of driver issues.
I tried with a different generic USB that is not as large, 2GB in size, and I could not reproduce the stalling/hang problem in File Explorer. I tried another USB flash drive, a Sandisk Extreme Pro USB 3.0 128GB, and the stalling/hang problem in file explorer returned. Tested both USBs on another computer with Windows 10 instead of Windows 11, and they too had the same stalling/hang problem.
So far, I am experiencing this issue with large capacity USB drives on Windows. The small capacity USBs mount instantly in File Explorer after Ventoy has formatted them.
Interesting, so it persists even on 2 completely different PCs running different Windows versions. Maybe indexing is slowing Explorer down? Well, since the drive is empty after being formatted, then there's nothing there to index, so it can't be indexing. Have you tried accessing the drive through CMD/Powershell to see if it hangs there?
