Having the same issue with a Hitachi 2TB desktop external USB3.0 HDD on a brand new Lenovo Ideapad Gaming 3 with Windows 11.
Factory specs: Lenovo IdeaPad Gaming 3 15IHU6 82K100LVUS 15.6" 120 Hz IPS Intel Core i5 11th Gen 11300H (3.10 GHz) NVIDIA GeForce RTX 3050 Laptop GPU 8GB Memory 256 GB PCIe SSD Windows 11 Home 64-bit Gaming Laptop. 2xUSB 3.2 Gen 1 (3.1 Gen 1) Type-A ports 1xUSB 3.2 Gen 1 (3.1 Gen 1) Type-C port.
When on my new windows 11 laptop it registers fine when the USB3.0 cable is plugged in then mid way through use it disconnects and reconnects. Alternatively It works fine on my older laptop with window 10 via it's usb 3.0 port.
looking for a fix for this problem.
