One thing to notice is that the laptop has 4 USB ports out of which 3 are 1.1 and only 1 is 2.0. The suspected faulty USB HDD Enclosure has 2 cables that I was connecting to, thus ending up connecting them to a 2.0 and 1.1 USB port. I tried with just 1 port connected to USB 2.0 port and haven't been able to reproduce the issue back again yet. :-( I also wasn't able to reproduce back the old issue with the pattern I mentioned in the previous post (1 cable connected to 1.1 and the other connected to 2.0 port) I'll keep testing and post to this thread if I find something useful.
