Hi - is there any update on this? I have the same enclosure (EC-SNVE) bought from Amazon in Nov last year and have been having random disconnection issues.
I updated the device's firmware from the product page, I also updated the firmware of the NVME drives I've tested with it (Samsung 970 EVO 500GB and WD Blue SN570 2TB). I found afterwards that the disconnections were still taking place. I've not had any issues with the heat pad though.
I did consider that it could be an issue with the connecting cable - I'm not using the supplied one as I only have USB-A ports avialble to test with. I've been using a UGREEN branded one and when it's worked it's been great. USB 3.2 gen1 transfer speeds of 850MBs while working.
I've now invested in a meatier cable (Amazon purchase, SUNGUY branded USB 3.1 gen2 USB-A to USB-C) and also a USB-C to USB-A adaptor to use in conjunction with the cable supplied with the device. I'll feed back on testing but wondered if there were any other suggestions?
