I have a similar issue and would like to know how to handle it. I appreciate any help.
I have a Rosewill External Data Storage drive. I have used the device on a Dell Laptop and was seeing the icon in My Computer. I was frequently using the drive to run a large file. I can't find the icon in the past few days on the Laptop or on my PC.
I do get an error message that says the device is not working or that I need to change the pathway to find the file.
On the Laptop, I thought the USB port was the problem, so I used every port when a error window would show. This idea worked for the last two months. Now nothing is bringing up the icon in My Computer.
