I've been experiencing problems with Kingston thumbdrives in Linux for over a year now but not Windows. Kingston thumbdrives tend to be slower and clunky in Linux for some reason I even tried entering: sudo tee /sys/module/usbcore/parameters/usbfs_memory_mb >/dev/null <<<0 in the terminal, with little noticeable change. The only thing I can think it could be is when I had the small surge go through my desktop when I was on my Linux HDD, maybe the Linux HDD is starting fail. Because whenever I use one of my Kingston thumbdrives on my Windows HDD I don't experience any issues for example I have this Kingston thumbdrive that has some ISO files on it and when I try putting it into the USB 3.0 port on Linux it doesn't recognize it but if put it into the USB 2.0 port it recognizes it, but in Windows this isn't a problem.
What do you think? Is my Linux HDD starting to fail? Or is there some other issue here?
